1968 Vehicle Tire Fitment Guide

Rim Diameter: 14 in  ·  Sidewalls: Dual-White-Stripe, Wide Whitewall, Narrow Whitewall

G78-14 is a bias-ply letter-series size used on larger 1968 domestic cars, including the 1968 American Motors Ambassador, 1968 Oldsmobile Vista Cruiser, and 1968 Pontiac Catalina and Tempest. Compared with smaller F-series or numeric 14-inch sizes, G78-14 generally points toward a fuller sidewall and a more substantial fitment for heavier vehicles. Product options span BFGoodrich and Coker Classic tires with narrow whitewall, dual-white-stripe, and wide whitewall treatments. Listed rim widths run from 5.00 to 7.00 inches, and the available load capacity reaches 1620 pounds at 32 psi, making this an important size for appearance and carrying requirements alike.

Rim Diameter: 14 in  ·  Sidewalls: Narrow Whitewall, Blackwall, Dual-Redline, RWL, Raised-White-Letter-Blue-Streak

695-14 is a compact-to-intermediate bias-ply size that appears on a broad mix of 1968 vehicles, from the 1968 American Motors Javelin and 1968 Ford Falcon to the 1968 Mercedes-Benz 220 and 1968 Plymouth Barracuda. Its cross-brand usage makes it one of the more versatile 14-inch domestic-era sizes on this page. Available BFGoodrich and US Royal products include blackwall, narrow whitewall, and dual-redline styles, with listed rim widths from 5.00 to 6.00 inches and a maximum load capacity of 1230 pounds at 32 psi. Buyers can use sidewall choice here to fine-tune either a restrained or sportier period presentation.

Rim Diameter: 14 in  ·  Sidewalls: Pin-White-Stripe, Redline, RWL

E70-14 is a performance-oriented 1968 bias-ply letter size used on sporty compact and pony-car applications such as the 1968 Ford Mustang, 1968 Mercury Cougar, 1968 Chevrolet Chevy II, and 1968 Pontiac Firebird. This is the kind of size often associated with late-1960s muscle-era styling, where sidewall branding and stripe treatment were part of the look. Available products include Firestone Wide Oval and Goodyear Custom Wide Tread tires in redline, pin-white-stripe, and RWL configurations. Product specs call for 14-inch wheels in the 6.00 to 7.00 inch range, so wheel width confirmation matters before ordering.

6.45-14 is a single-application 1968 bias-ply size listed for the 1968 American Motors Rambler. It reflects the older numeric domestic sizing convention still found on some compact and economy-oriented cars of the period. No current product details are attached to this size here, so it should be treated as a fitment reference point rather than a product-led category. For a 1968 Rambler, this size is a reminder that even within one make, smaller models could use a noticeably different tire format than larger or sportier stablemates. Wheel diameter, present wheel type, and overall restoration direction should be verified carefully.

Rim Diameter: 13 in  ·  Sidewalls: Wide Whitewall

640-13 is a bias-ply 13-inch size used on the 1968 Amphicar Amphicar and on the 1968 Ford-Taunus 17M and 20M. The numeric format is typical of period bias-ply sizing and points to a relatively small-diameter application compared with many American midsize fitments of the same year. The available BFGoodrich Silvertown Classic Bias Ply product is offered as a 2.25-inch wide whitewall for 13-inch rims with a listed 4.00 to 4.50 inch width range and a 1045-pound maximum load capacity at 32 psi. This size is especially relevant for owners aiming to preserve a distinctly period-correct visual profile.

Rim Diameter: 13 in  ·  Sidewalls: Wide Whitewall, Narrow Whitewall

650-13 is a bias-ply size used on several compact 1968 vehicles, including the 1968 Amphicar Amphicar, 1968 Dodge Dart, 1968 Plymouth Valiant, 1968 Triumph 2000, and 1968 Austin 1800. Even within a diverse year like 1968, this size reflects a smaller, lighter-duty 13-inch fitment than those found on domestic intermediates and full-size cars. Available choices from Coker Classic and US Royal include wide whitewall and narrow whitewall styles, all specified for 13-inch wheels with 4.50 to 5.00 inch rim widths. With a listed maximum load capacity of 1150 pounds at 32 psi, this size balances compact proportions with practical road use.

Rim Diameter: 15 in  ·  Sidewalls: Redline, Narrow Whitewall, Blackwall

185R15 is a radial size used on a strong group of 1968 European touring and sports cars, including the 1968 Aston Martin DB, 1968 Citroen DS, 1968 Jaguar XKE, and 1968 Peugeot 404. This metric radial format suits owners looking for an established European-style fitment, and it appears across several marques that value road feel and high-speed stability. Product options include Coker Classic and Michelin XVS tires in blackwall, narrow whitewall, and redline styles. Certain listings specify 15-inch wheel fitment from 4.5 to 6.50 inches wide, with available load capacity up to 1355 pounds at 35 psi on one product.

Rim Diameter: 15 in  ·  Sidewalls: Redline, Narrow Whitewall, Goldline, Blackwall, Raised-White-Letter-Blue-Streak, Blue-Dot

775-15 is a bias-ply size used on the 1968 Aston Martin DB and certain full-size 1968 Ford applications. That pairing alone shows how 1968 tire fitment can cross very different vehicle classes while still demanding close attention to the exact car and wheel. Product selection is broad, with BFGoodrich and Firestone offerings that include redline, narrow whitewall, and goldline sidewall styles. Listed wheel fitments include 15-inch rims, with some products showing 4.50 to 5.00 inch widths and others calling out a 6-inch wheel. Buyers should match the sidewall treatment and wheel dimensions to the specific vehicle configuration rather than the year alone.

Rim Diameter: 15 in  ·  Sidewalls: Wide Whitewall, Blackwall

205R15 is a radial size associated with upper-end 1968 European grand touring, luxury, and specialty vehicles, including the 1968 Aston Martin DBS, 1968 Ferrari 330, several 1968 Maserati models, the 1968 Rolls Royce Silver Shadow, and the 1968 Rover 88. This metric radial fitment points to larger, more substantial cars than the smaller 155R15 or 165R15 group. Current products include a Phoenix European Passenger tire with a 2.50-inch whitewall and an Avon Turbosteel blackwall radial. One listing specifies a 15-inch rim width range of 5.50 to 6.00 inches and a maximum load capacity of 1609 pounds at 34 psi.

Rim Diameter: 12 in  ·  Sidewalls: Blackwall

145R12 is a compact radial size used on smaller 1968 British cars such as the 1968 Austin 1100, 1968 Austin America, 1968 MG 1100, and 1968 Singer Chamois. This metric radial fitment is closely tied to lightweight, small-wheel applications where overall tire diameter and section width are modest compared with larger 13-, 14-, and 15-inch fitments from the same year. The available product is a Michelin MX blackwall radial with a listed 12-inch rim diameter and 4.5-inch rim width. For these compact cars, maintaining the intended proportions can be especially important for steering feel, gearing character, and fender clearance.

5.50-12 is a bias-ply size used on a mix of compact 1968 cars including the 1968 Austin 1100, 1968 Fiat 850, 1968 MG 1100, 1968 Sunbeam Imp, and 1968 Vauxhall Viva. As a small-diameter numeric bias-ply size, it offers a more period-oriented construction choice for vehicles that may also appear with radial alternatives in nearby categories. No product detail is attached for this exact size here, but its appearance across several small imports underscores how common 12-inch fitment remained in certain segments. Buyers should pay particular attention to present wheel condition and body clearance on these tighter, compact applications.

175R13 is a radial fitment used on the 1968 Austin 1800, 1968 Ford-Taunus 17M, 1968 Ford-Taunus 20M, and 1968 Triumph 2000. This size sits above the smallest import radial sizes and suits larger compact or mid-sized European cars that need a little more footprint than 145- or 155-section tires. No product details are attached here, so it works mainly as a vehicle-size guidepost within the 1968 fitment landscape. For anyone researching a 1968 European sedan in this group, the key takeaway is that tire choice should follow the exact model and wheel setup, not just the make or general vehicle class.

Rim Diameter: 10 in  ·  Sidewalls: Blackwall

145R10 is a very compact radial size tied to 1968 small-car icons such as the 1968 Austin Mini Cooper and 1968 Morris Mini Minor. With a 10-inch rim diameter, this fitment is distinct from nearly everything else on the page and highlights just how specialized some 1968 applications can be. Product choices include blackwall radials from Firestone, Kings, Camac, and Dunlop, with listed maximum load capacity up to 694 pounds at 30 psi on one option. These tires are especially relevant for owners trying to preserve the quick, nimble character associated with tiny-wheel British compacts.

5.20-10 is the bias-ply companion to the small 145R10 radial fitment used on the 1968 Austin 850, 1968 Austin Mini Cooper, 1968 Morris Mini Cooper, and 1968 Morris Mini Minor. The size reflects the compact, narrow proportions typical of small British cars using 10-inch wheels in the late 1960s. No product details are listed here, but the fitment itself is important because construction choice can significantly affect ride character and period appearance on short-wheelbase cars. Owners comparing options should keep wheel diameter, body clearance, and the intended balance between vintage feel and radial behavior in mind.

Rim Diameter: 13 in  ·  Sidewalls: Blackwall

145R13 is a radial fitment used across smaller 1968 imports and sports cars, including the 1968 Austin A 40, 1968 Austin-Healey Sprite, 1968 Lotus Europa, 1968 MG Midget, and 1968 Simca 1000. This metric radial size supports lightweight applications where preserving compact dimensions is central to the car’s handling balance and stance. Available products are blackwall radials from Michelin and Firestone, with one Firestone listing specifying 13-inch rims from 4.00 to 5.00 inches wide and a maximum load capacity of 825 pounds at 44 psi. It is a focused size for small-displacement, low-mass 1968 cars rather than general passenger use.

Rim Diameter: 13 in  ·  Sidewalls: Blackwall, Narrow Whitewall, Wide Whitewall

520-13 is a small bias-ply size found on 1968 compact European and British vehicles such as the 1968 Austin-Healey Sprite, 1968 DAF Daffodil, 1968 Lotus Elan, and 1968 Lotus Europa. This size is useful for owners who want a period-style bias-ply format on light cars that may also be researched through radial metric sizing. Product offerings include Firestone blackwall and several Premium Sport narrow whitewall tires, with certain listings specifying 13-inch rims around 3.5 to 4.00 inches wide. Because these vehicles are light and often compact around the wheel openings, proper wheel width and overall tire profile deserve careful attention.

5.95-12 is a single-application bias-ply size listed for the 1968 Austin America. It represents one of the more specialized small-wheel fitments in the 1968 range, and it should not be assumed interchangeable with other 12-inch Austin applications without confirming the exact model. No product details appear here for this size, so its main value on the page is as a precise fitment reference. For an Austin America, the difference between nearby 12-inch sizes can matter in both stance and clearance, making it especially important to verify the existing wheel setup and the tire size already associated with the car.

Rim Diameter: 14 in  ·  Sidewalls: Blackwall

165R14 is a radial size used across a mix of 1968 European sedans, roadsters, and imports, including the 1968 BMW 1500, 1968 BMW 1800, 1968 MG MGB, 1968 Rover 2000, and 1968 Vauxhall Cresta. This is a versatile 14-inch metric radial category that bridges modest sports cars and practical sedans. Product choices include blackwall radials from Pirelli, Michelin, and Vredestein, with listed rim width guidance ranging from 4.0 to 6.00 inches depending on the product. When shopping this size, buyers often focus on brand character and sidewall appearance less than on maintaining the proper European touring-car proportions.

6.00-14 is a bias-ply size used on the 1968 BMW 1500, 1968 BMW 1600, 1968 BMW 1800, and the 1968 Nissan L320 and L520. This pairing shows how one older numeric size could serve both passenger-car and light-duty utility applications during the period. No current product details are attached for this size here, so it mainly functions as an important fitment marker for vehicles that may be researched alongside metric radial alternatives. For 1968 BMW and Nissan owners, the distinction between 6.00-14 and nearby radial sizes can shape both appearance and driving feel, especially on stock-diameter wheels.

Rim Diameter: 13 in  ·  Sidewalls: Blackwall

165R13 is a radial fitment used on a wide selection of 1968 smaller cars, including the 1968 BMW 2002, 1968 Fiat 124, 1968 Lotus Elan, 1968 Nissan PL510, 1968 Sunbeam Alpine, and 1968 Toyota Corona. The size is especially relevant for compact sedans and nimble sports cars that benefited from the then-modern metric radial format. Product options include blackwall radials from Michelin and Dunlop, with certain listings calling for 13-inch rims from 4.50 to 6.00 inches wide and up to 1,047 pounds of load capacity. This is a strong category for buyers seeking a classic European-style radial presentation.

Rim Diameter: 13 in  ·  Sidewalls: Wide Whitewall, Narrow Whitewall

600-13 is a bias-ply size shared by several 1968 compact imports and sports cars, including the 1968 BMW 2002, 1968 Ford Cortina, 1968 Lotus Elan, 1968 Sunbeam Arrow, and 1968 Toyota Corona. As a period numeric bias-ply fitment, it provides an alternative path for owners who want a more traditional sidewall shape and vintage appearance. Available BFGoodrich Silvertown Classic Bias Ply products come in wide whitewall and narrow whitewall styles, both for 13-inch rims with a 4.00 to 4.50 inch width range and a stated 1010-pound maximum load at 32 psi. It is a compact size, but one with broad 1968 application coverage.

Rim Diameter: 14 in  ·  Sidewalls: Blackwall

175R14 is a radial size used on larger compact and midsize 1968 imports such as the 1968 BMW 2000, 1968 Fiat 1800, 1968 Mercedes-Benz 220, 1968 Mercedes-Benz 230, 1968 Mercedes-Benz 250, and 1968 Toyota Crown. This metric radial format offers a useful middle ground between narrower European sedan sizes and the larger luxury or GT fitments found elsewhere on the page. Product choices from Michelin and Vredestein are offered in blackwall form, with some listings specifying 14-inch wheel widths from 4.5 to 6.0 inches and a maximum load capacity up to 1,235 pounds at 51 psi.

Rim Diameter: 15 in  ·  Sidewalls: Narrow Whitewall, Whitewall-Redline

815-15 is a bias-ply size used on larger 1968 luxury and full-size cars including the 1968 Bentley T, selected 1968 Ford models, 1968 Ford Thunderbird, 1968 Plymouth Fury, and 1968 Rolls Royce Silver Shadow. This is a substantial 15-inch fitment associated with heavier vehicles and longer-wheelbase applications. Available BFGoodrich Silvertown Classic Bias Ply products include a narrow whitewall and a whitewall-redline combination, both listed for 15-inch rims with widths from 5.00 to 6.50 inches and a maximum load capacity of 1610 pounds at 32 psi. For these cars, sidewall style can have a major effect on the finished period look.

195R15 is a radial size listed specifically for the 1968 Bristol 410. As a single-model fitment, it occupies a specialty position in the 1968 landscape and should be matched carefully to the exact vehicle and wheel setup. The available product is a blackwall radial from Bristol’s listed product group, with a 15-inch rim diameter noted, but without a stated rim width in this category. Because 195R15 sits between smaller European sedan sizes and larger grand-touring fitments, it is especially important not to substitute based on appearance alone. Exact size identification remains the best starting point for a Bristol 410.

Rim Diameter: 15 in  ·  Sidewalls: Blackwall, Wide Whitewall, Narrow Whitewall

670-15 is a bias-ply size listed for the 1968 Bristol 410 and supported by a wide range of product styles. This makes it an interesting option for buyers researching a specialty British application while still wanting multiple period-looking tire choices. Available products include Firestone, US Royal, Coker Classic, and Universal Vintage Tire offerings in blackwall and wide whitewall styles. Several products specify 15-inch rims with width ranges from 4.50 to 6.00 inches, and stated load capacities reach 1550 pounds at 32 psi on one listing. It is a useful category where sidewall appearance can materially shape a restoration’s final presentation.

8.85-15 is a large bias-ply size used on heavy 1968 American luxury and premium models such as the 1968 Buick Electra 225, 1968 Buick Wildcat, 1968 Chrysler disc brake equipped models, 1968 Oldsmobile 98 Series, and 1968 Oldsmobile Toronado. It represents a traditional full-size American 15-inch fitment rather than a sport-oriented letter-series size. No product details are attached here, so this size serves mainly as an application guide within the year. When evaluating a car in this group, overall vehicle weight, brake package, and wheel condition matter just as much as the size marking itself because these are substantial, load-sensitive applications.

8.45-15 is a bias-ply full-size 15-inch size shared by several 1968 American cars, including the 1968 Buick LeSabre, 1968 Buick Riviera, 1968 Ford Thunderbird, 1968 Lincoln Continental, and 1968 Plymouth Fury. The fitment points toward larger domestic sedans and personal luxury cars rather than compact or intermediate platforms. No product specifics are listed here, but its placement alongside other large 15-inch sizes shows how closely 1968 full-size tire selection depends on exact model and trim grouping. For a car in this category, checking wheel diameter and body clearance is especially helpful, since similar-looking cars from the same year may still use different 15-inch sizes.

Rim Diameter: 14 in  ·  Sidewalls: Pin-White-Stripe, Redline, RWL

F70-14 is one of the key 1968 muscle-era bias-ply performance sizes, appearing on vehicles such as the 1968 Buick Skylark, 1968 Chevrolet Camaro, 1968 Dodge Charger, 1968 Ford Mustang, 1968 Mercury Cougar, and 1968 Pontiac Firebird. This letter-series size is closely associated with sporty domestic applications where stance and sidewall treatment are part of the car’s visual identity. Product choices include Firestone Wide Oval and Goodyear Custom Wide Tread lines in redline, pin-white-stripe, and RWL styles. Listed wheel fitment generally falls in the 6.00 to 7.00 inch rim-width range, making wheel selection a meaningful part of proper fitment.

Rim Diameter: 14 in  ·  Sidewalls: Narrow Whitewall

855-14 is a larger bias-ply 14-inch size used on many 1968 full-size domestic cars, including the 1968 Chrysler New Yorker, 1968 Chrysler Newport & 300 Series, 1968 Oldsmobile 88 Series, 1968 Plymouth Fury, and 1968 Pontiac Catalina. It is typical of heavier American sedans and wagons that remained on 14-inch wheels while still requiring meaningful load capacity. Available BFGoodrich Silvertown Classic Bias Ply tires are offered in two narrow whitewall widths, both listed for 14-inch rims with widths from 5.50 to 6.00 inches and a maximum load capacity of 1740 pounds at 32 psi. This size emphasizes load support and authentic domestic proportions.

Rim Diameter: 15 in  ·  Sidewalls: Narrow Whitewall, Blackwall, Wide Whitewall

820-15 is a heavy-duty bias-ply 15-inch size listed for the 1968 Cadillac 75 Series. This application sits firmly in the large luxury and formal-car category, where tire load capacity, overall diameter, and sidewall appearance all play an outsized role. Product selection is extensive, with BFGoodrich, Firestone, and US Royal choices in blackwall, narrow whitewall, and wide whitewall styles. Listed rim widths run from 6.00 to 6.50 inches, and several products carry a 1920-pound maximum load rating at 32 psi. For long-wheelbase Cadillac use, this is not a casual substitution size and should be matched with careful attention to wheel specification.

Rim Diameter: 15 in  ·  Sidewalls: Wide Whitewall, Blackwall

890-15 is a very large bias-ply 15-inch size used on the 1968 Cadillac Commercial Series, a vehicle class with different tire demands than ordinary passenger sedans. Available products include Firestone wide whitewall choices and an Avon Turbospeed blackwall, all centered on a 15-inch rim diameter with a listed width range of 6.50 to 7.00 inches on some products. Firestone listings show a maximum load capacity of 2500 pounds at 40 psi, underscoring the heavier-duty nature of this size. For specialized 1968 commercial or coachbuilt applications, load rating is every bit as important as maintaining the proper visual profile.

Rim Diameter: 15 in  ·  Sidewalls: Triple-White-Stripe, Narrow Whitewall, Dual-White-Stripe, Blackwall

900-15 is a large bias-ply 15-inch fitment used on the 1968 Cadillac Eldorado, 1968 Cadillac Standard Models, and 1968 Mercedes-Benz 600. This is one of the clearest examples of a substantial luxury-class size that crosses American and European prestige cars from the same year. Product options include BFGoodrich Silvertown Classic Bias Ply tires in triple-white-stripe, narrow whitewall, and dual-white-stripe styles, plus an M&H Vintage Drag Slick blackwall product with a drag-race attribute. Most listed passenger-style products fit 15-inch rims 6.50 to 7.00 inches wide and carry a 1920-pound maximum load rating at 32 psi.

Rim Diameter: 14 in  ·  Sidewalls: Redline, RWL, Pin-White-Stripe, Blackwall

G70-14 is a bias-ply performance size listed for the 1968 Chevrolet Chevelle, representing a wider late-1960s domestic performance format than smaller E70-14 and F70-14 fitments. Product selection includes Firestone Wide Oval and Goodyear Custom Wide Tread tires in redline, RWL, and pin-white-stripe styles. Listed wheel fitment generally falls around 14-inch rims with widths from 6.0 to 8.0 inches depending on the product, and available load capacity reaches 1620 pounds at 32 psi. This size is especially relevant when the goal is a broad-shouldered muscle-car stance combined with a sidewall treatment that matches the vehicle’s overall era presentation.

8.25-15 is a bias-ply 15-inch size shared by several 1968 full-size American cars, including the 1968 Chevrolet Impala, selected 1968 Ford models, 1968 Ford Thunderbird, 1968 Mercury All Models, and 1968 Plymouth Fury. It represents a mainstream large-car fitment rather than a compact, imported, or letter-series performance size. No current product details are attached here, so the size primarily serves as a fitment identifier for large domestic applications. Because several big Ford, Chevrolet, Mercury, and Plymouth models use similar but not identical 15-inch sizes in 1968, buyers should confirm the exact model grouping before moving to product selection.

Rim Diameter: 13 in  ·  Sidewalls: Wide Whitewall

700-13 is a bias-ply size used on the 1968 Chevrolet Corvair, 1968 Dodge Dart, 1968 Mercedes-Benz 190, 1968 Mercedes-Benz 200, 1968 Mercedes-Benz 230, and 1968 Plymouth Valiant. Its application range is unusually broad, covering both American compact cars and selected European sedans. The available product is a Firestone wide whitewall bias-ply tire for 13-inch rims with a listed width range of 4.00 to 5.00 inches and a maximum load capacity of 1270 pounds at 32 psi. For 1968 cars in this group, the exact size matters because neighboring 13-inch fitments can differ noticeably in overall section and intended vehicle role.

Rim Diameter: 15 in  ·  Sidewalls: Pin-White-Stripe, Redline, RWL

F70-15 is a bias-ply performance size used on the 1968 Chevrolet Corvette and the 1968 Plymouth Belvedere & Satellite. That combination highlights how one letter-series size could serve both dedicated sports-car and high-performance domestic applications in 1968. Product offerings from Firestone and Goodyear include redline, RWL, and pin-white-stripe sidewall treatments, with listed 15-inch rim width ranges stretching from 5.50 to 8.00 inches depending on the tire. Because this size is so style-sensitive, buyers often choose based not only on dimensions but also on whether the vehicle’s visual goal leans toward factory-era muscle, road-sport, or custom period presentation.

Rim Diameter: 15 in  ·  Sidewalls: Redline, RWL, Pin-White-Stripe

G70-15 is a bias-ply performance size used on the 1968 Chevrolet Impala and 1968 Ford GT. This is a wider, more assertive 15-inch letter-series fitment than many standard domestic passenger sizes and is strongly connected with performance-oriented late-1960s American styling. Available products from Firestone and Goodyear include redline, RWL, and pin-white-stripe variations, with wheel fitment typically listed from 5.50 to 8.00 inches wide depending on the product. The combination of generous wheel-width range and multiple sidewall styles makes G70-15 a highly visual choice where both fitment and finished appearance deserve equal attention.

Rim Diameter: 14 in  ·  Sidewalls: Narrow Whitewall

885-14 is a large bias-ply 14-inch size listed for the 1968 Chrysler Newport & 300 Series, 1968 Chrysler Town & Country, 1968 Oldsmobile 98 Series, and 1968 Pontiac Pontiac. This is a full-size domestic fitment associated with heavier, more substantial cars rather than intermediate or sporty 14-inch applications. The available product is a BFGoodrich Silvertown Classic Bias Ply narrow whitewall with a 15-inch-class visual presence on a 14-inch rim, specified for a 6-inch wheel and a maximum load capacity of 1860 pounds at 32 psi. It is a size where proper load support and overall vehicle stance go hand in hand.

180-380 is a radial size used on the 1968 Citroen DS, 1968 Citroen ID, and 1968 Citroen SW. Unlike the more familiar inch-based domestic sizes or common metric radial entries such as 165R15, this fitment follows a distinct European convention and should be handled as a specialized application. No product details are attached here, so the size functions mainly as an important Citroen-specific fitment reference. For owners of these 1968 Citroen models, exact size identification is critical because wheel and tire systems on European cars of this era can differ significantly from mainstream American sizing assumptions.

Rim Diameter: 14 in  ·  Sidewalls: RWL, Redline, Pin-White-Stripe

D70-14 is a bias-ply performance size used on the 1968 Dodge Dart and 1968 Plymouth Barracuda. It sits on the smaller side of late-1960s domestic letter-series performance sizing and is associated with compact sporty applications rather than big-body muscle cars. Available Firestone Wide Oval products come in RWL, redline, and pin-white-stripe styles, all listed for 14-inch rims with a 6-inch wheel width and a maximum load capacity of 1320 pounds at 32 psi. This size is a good example of how sidewall treatment was part of the package on performance-oriented 1968 compacts.

Rim Diameter: 14 in  ·  Sidewalls: Blackwall

205R14 is a radial size used on the 1968 Ferrari 275, 1968 Ferrari 320, and 1968 Jaguar 420. This is a specialty European performance and grand-touring fitment rather than a broad-market 14-inch size. The available product is the Michelin XWX blackwall radial, specified for 14-inch rims from 5.50 to 7.50 inches wide. That generous width range and the model applications involved make this a serious fitment category where exact wheel specification matters. For owners of these 1968 cars, maintaining the correct tire size is especially important because both handling balance and visual proportion can be affected by seemingly small changes.

Rim Diameter: 13 in  ·  Sidewalls: Blackwall

155R13 is a radial fitment used on a large and varied set of 1968 European and compact cars, including the 1968 Fiat 124, 1968 Ford Cortina, 1968 Opel Kadett, and 1968 Triumph Spitfire. It is one of the stronger examples of a broadly shared metric radial size for smaller-displacement vehicles from the period. Product choices are blackwall radials from Michelin and Dunlop, with one Michelin listing specifying a 13-inch wheel and rim widths from 4.00 to 5.50 inches. For buyers comparing compact 1968 imports, 155R13 often sits at the center of the radial conversation.

560-13 is the bias-ply counterpart used across many of the same compact 1968 European and British applications found with 155R13, including the 1968 Fiat 124, 1968 Ford Cortina, 1968 Nissan PL510, and 1968 Triumph GT6. This size suits owners prioritizing an earlier-style sidewall shape and period-correct bias-ply presentation. Available products from BFGoodrich and Firestone include narrow whitewall and wide whitewall styles, with listed 13-inch rim widths from 3.50 to 4.50 inches and a maximum load capacity of 850 pounds at 30 psi. It is a compact size where appearance and authenticity goals often guide the final choice.

6.15-13 is a single-application bias-ply size listed for the 1968 Fiat 124. That makes it a specialized fitment reference within a model line that also appears with other sizes, including metric radial and smaller numeric alternatives. No product details are attached here, so this entry primarily helps identify the exact tire-size path associated with a particular 1968 Fiat 124 configuration. Because the Fiat 124 appears with more than one size family, it is important to confirm the wheel diameter and the tire size already associated with the vehicle rather than assuming every 124 uses the same tire.

Rim Diameter: 14 in  ·  Sidewalls: Blackwall

145R14 is a radial size used on the 1968 Fiat 1500 and 1968 Lancia Fulvia. This narrow metric radial fitment is tied to compact European passenger-car applications where preserving light steering and proper overall proportions is often a priority. Product choices include blackwall radials from Firestone and Camac, with one Firestone listing specifying 14-inch rims from 4.00 to 5.00 inches wide and a maximum load capacity of 880 pounds at 44 psi. Since this size serves only a small group of 1968 models here, it should be matched carefully to the exact car rather than generalized across other Lancia or Fiat applications.

Rim Diameter: 14 in  ·  Sidewalls: Narrow Whitewall

520-14 is a bias-ply size used on the 1968 Fiat 1500, 1968 Lancia Fulvia, 1968 MG MGB, and 1968 Morris Minor. As a smaller 14-inch numeric size, it reflects the continued overlap between older bias-ply sizing and newer radial conventions during the late 1960s. Available products come from Premium Sport and are offered in narrow whitewall form, with some listings specifying 14-inch rim widths from 3.50 to 4.00 inches and a maximum load capacity of 1230 pounds at 60 psi. This is a narrow fitment category where the intended visual character of the car often plays a major role in selection.

5.90-14 is a bias-ply size listed for the 1968 Fiat 1500, 1968 MG MG, and 1968 Vauxhall Cresta. It occupies a useful middle ground among 14-inch period sizes, serving a handful of import applications without the broad domestic overlap seen in 735-14 or 775-14. No current product details are shown here, so the size functions mainly as a fitment reference. When dealing with 1968 imported cars in this category, it helps to verify whether the vehicle is being kept in a traditional bias-ply format or researched alongside a metric radial alternative, since some models from this era appear in both styles.

Rim Diameter: 15 in  ·  Sidewalls: Wide Whitewall, Narrow Whitewall, Blackwall

165R15 is one of the strongest shared radial fitments in the 1968 range, appearing on the 1968 Porsche 911, 1968 Porsche 912, 1968 Triumph TR3, TR4 & TR4A, 1968 Volkswagen Fastback, several Volvo models, and others. It serves a broad group of European cars, from sports cars to practical sedans and wagons. Product selection is extensive, with Coker Classic, American Classic, Firestone, and BFGoodrich offerings in blackwall, narrow whitewall, and wide whitewall styles. Several products specify 15-inch rims from 4.50 to 6.00 inches wide and load capacities around 1168 to 1170 pounds, making this a versatile yet still size-sensitive category.

Rim Diameter: 15 in  ·  Sidewalls: Blackwall, Wide Whitewall

590-15 is a bias-ply size used on the 1968 Fiat 1800, 1968 Morgan Plus 4, 1968 Peugeot 404, and 1968 Triumph TR3, TR4 & TR4A. This older numeric 15-inch format gives owners of several British and European classics a distinctly period-style bias-ply option alongside certain radial listings elsewhere in the year. Product choices include BFGoodrich and Avon blackwall options, plus a BFGoodrich wide whitewall. Listed rim widths run from 4.00 to 4.50 inches, with maximum load capacities around 1018 to 1050 pounds where stated. It is a specialized size that favors careful wheel matching over broad interchange assumptions.

6.40-14 is a single-application bias-ply size listed for the 1968 Fiat 1800. It reflects the variety found even within one model line during 1968, where some vehicles appear with more than one tire-size convention. No product details are attached here, so this entry serves primarily as an exact fitment identifier. For a 1968 Fiat 1800, that matters because neighboring sizes such as 175R14 are not simply cosmetic alternatives; they represent different sizing systems and potentially different wheel considerations. Exact size, wheel diameter, and the vehicle’s present configuration should be confirmed before narrowing product options.

155R12 is a radial size used on the 1968 Fiat 850, 1968 Simca 1000, and 1968 Sunbeam Imp. Compared with the smaller 145R12 group, this size provides a slightly larger metric radial fitment for compact 12-inch applications. No product details are attached here, so the size functions mainly as a guide for matching the proper 1968 vehicle and wheel setup. Because these small cars often have tight wheel openings and light curb weights, even modest differences in tire section and overall profile can be noticeable. Exact model identification is the best way to separate this size from other nearby 12-inch options.

Rim Diameter: 14 in  ·  Sidewalls: Blackwall, Narrow Whitewall

185R14 is a radial size used on a varied set of 1968 vehicles that includes the 1968 Fiat Dino, 1968 Mercedes-Benz 250, 1968 Mercedes-Benz 280, 1968 Mercedes-Benz 300, 1968 Vauxhall Viscount, and 1968 Volkswagen Station Wagon. That broad mix makes it an important category for larger European sedans, specialty coupes, and wagons. Product options include Michelin, Phoenix, and Vredestein tires in blackwall and narrow whitewall styles. Listed rim fitments run from 4.00 to 6.50 inches or 4.5 to 6.0 inches depending on the product, with stated load capacity up to 1323 pounds at 35 psi on one listing.

Rim Diameter: 14 in  ·  Sidewalls: RWL

FR70-14 is a radial-style fitment used on the 1968 Ford Fairlane/Torino, 1968 Ford Mustang, 1968 Mercedes-Benz 300, and 1968 Mercury Cougar. The available product is a Goodyear Polyglas Radial with a bias-look radial construction and RWL sidewall, which makes this size especially relevant for owners who want a late-1960s performance appearance while moving into radial construction. The tire is specified for a 14-inch rim with a 6-inch width and a maximum load capacity of 1500 pounds at 32 psi. This is a particularly style-conscious category, where appearance and construction type intersect more directly than usual.

Rim Diameter: 15 in  ·  Sidewalls: Narrow Whitewall

855-15 is a bias-ply 15-inch size used on large 1968 domestic cars and wagons including the 1968 Ford Thunderbird, 1968 Mercury All Models, 1968 Mercury Wagons, 1968 Oldsmobile 88 Series, and 1968 Plymouth Fury. It sits in the full-size American category where load capacity and sidewall style both matter. Available BFGoodrich Silvertown Classic Bias Ply products are narrow whitewall tires in two stripe widths, both listed for 15-inch rims measuring 6.00 to 6.50 inches wide and carrying a maximum load capacity of 1710 pounds at 32 psi. This size is especially relevant to owners restoring bigger cars with an authentic late-1960s stance.

Rim Diameter: 15 in  ·  Sidewalls: RWL, Blackwall

E70-15 is a bias-ply performance size listed for the 1968 Ford Shelby Mustang. As a single-model application on this page, it stands out as a focused muscle-era fitment rather than a shared domestic size. Product options from Firestone and Goodyear include RWL and blackwall styles, with several listings specifying 15-inch wheels in the 6.50 to 8.00 inch range and a maximum load capacity of 1400 pounds at 32 psi. The size is strongly tied to late-1960s performance aesthetics, so wheel width, sidewall lettering, and the car’s intended visual goal should all be considered together.

Rim Diameter: 13 in  ·  Sidewalls: Wide Whitewall

590-13 is a single-application bias-ply size listed for the 1968 Ford-Taunus 12M. It is a compact numeric 13-inch fitment and should be treated as distinct from other 560-13, 600-13, or metric 13-inch sizes found elsewhere in the 1968 range. The available product is a BFGoodrich Silvertown Classic Bias Ply wide whitewall specified for a 13-inch rim with a 3.50 to 4.00 inch width range and a maximum load capacity of 970 pounds at 32 psi. For an imported compact like the 12M, maintaining the proper narrow-wheel relationship is a key part of correct fitment.

215R15 is a radial size used on the 1968 ISO Grifo and 1968 Lincoln Continental, an unusual pairing that spans both exotic European performance and large American luxury. That alone makes this one of the more specialized 1968 radial categories. No product details are attached here, so it functions mainly as a fitment reference rather than a product-rich size page. Because these are very different vehicles despite sharing the same size, buyers should never assume interchangeable wheel widths, body clearances, or intended driving character. Exact model confirmation remains essential before narrowing any product or construction choice.

9.15-15 is a large bias-ply size used on the 1968 Imperial All Models and 1968 Lincoln Continental. This is a substantial 15-inch full-size luxury fitment tied to some of the biggest passenger cars represented for 1968. No product details are attached here, so the size primarily serves as a precise application marker. Its presence alongside somewhat smaller 8.45-15 and 8.85-15 entries is a reminder that even similar large American luxury cars could require different tire sizes. For these heavy applications, exact sizing, wheel condition, and present vehicle configuration are especially important when planning a replacement set.

Rim Diameter: 15 in  ·  Sidewalls: Wide Whitewall, Narrow Whitewall, Blackwall

640-15 is a bias-ply size used on the 1968 Jaguar 340, 1968 Jaguar 420, 1968 Jaguar XKE, and 1968 Volvo 122. This shared fitment links British sporting and sedan applications with a classic Volvo passenger car, illustrating the overlap of certain 15-inch sizes across European brands in 1968. Available products from BFGoodrich and Firestone include wide whitewall and narrow whitewall styles, with listed rim widths generally from 4.00 to 5.00 inches and maximum load capacity around 1190 pounds at 32 psi on several offerings. It is a useful size for buyers seeking a traditional bias-ply look on mid-century European classics.

Rim Diameter: 14 in  ·  Sidewalls: Blackwall

155R14 is a radial size used on the 1968 Lancia Fulvia, 1968 MG MGB, and 1968 Morris Minor. This metric radial fitment suits relatively light 14-inch applications and can be especially appealing when owners want a classic road-car look with radial construction. Available products are blackwall radials from Michelin and Firestone, with the Firestone listing showing a 14-inch rim width range of 4.00 to 5.50 inches and a maximum load capacity of 990 pounds at 44 psi. Because it appears on a limited group of vehicles here, 155R14 should be confirmed carefully rather than assumed from make or model family alone.

Rim Diameter: 15 in  ·  Sidewalls: Pin-White-Stripe, RWL

GR70-15 is a radial-style fitment listed for the 1968 Maserati Ghibli. Available products come from Goodyear and use bias-look radial construction, with sidewall styles that include pin-white-stripe and RWL. This makes GR70-15 especially relevant for shoppers seeking a period performance appearance without moving to a plain modern radial look. Product specifications show 15-inch wheel fitment, with several options calling for rim widths from 7.0 to 8.0 inches or 7.50 to 8.0 inches depending on the tire. On an application as specialized as a 1968 Maserati Ghibli, wheel width and stance are central to proper selection.

Rim Diameter: 13 in  ·  Sidewalls: Blackwall

185R13 is a radial size listed for the 1968 Mercedes-Benz 190 and 1968 Mercedes-Benz 230. Compared with narrower 165R13 fitments, this size points to a larger section width within the same general wheel-diameter class. The available product is a Michelin XAS-FF blackwall radial, specified for a 13-inch rim and carrying a listed weight, but without a stated rim-width range in this category. Since this size appears only within a limited Mercedes-Benz group for 1968, it should be matched carefully to the exact model configuration. Even within one marque, not every sedan of the same year shares the same tire dimensions.

Rim Diameter: 13 in  ·  Sidewalls: Blackwall, Wide Whitewall

725-13 is a bias-ply size listed for the 1968 Mercedes-Benz 200. As a single-application 13-inch fitment on this page, it stands apart from broader shared sizes and should be treated as model-specific. Available BFGoodrich Silvertown Classic Bias Ply products include a blackwall and a 2.25-inch wide whitewall, with the whitewall listing specifying a 13-inch rim width range of 4.50 to 5.50 inches and a maximum load capacity of 1360 pounds at 32 psi. This is a good example of how 1968 tire fitment within one European make can still vary noticeably from one model to another.

195R14 is a radial size listed specifically for the 1968 Mercedes-Benz 280. It occupies a relatively uncommon place in the 1968 fitment spectrum, larger than many compact European 14-inch sizes and more specialized than broad-market domestic 14-inch entries. No product details are attached here, so the size is best understood as a precise fitment reference for this Mercedes-Benz application. For a 1968 Mercedes-Benz 280, identifying whether the car is associated with 185R14 or 195R14 is particularly important, since close-looking metric sizes can carry different proportions and may suit different wheel widths or configurations.

Rim Diameter: 14 in  ·  Sidewalls: Wide Whitewall, Blackwall, Narrow Whitewall

560-14 is a bias-ply size used on the 1968 Nissan 2000, 1968 Nissan L320, 1968 Nissan L520, and 1968 Rover 2000. This compact numeric 14-inch fitment covers both passenger and utility applications, making it one of the more flexible small-to-medium bias-ply sizes in the 1968 range. Available BFGoodrich Silvertown Classic Bias Ply products include blackwall, narrow whitewall, and wide whitewall choices, all specified for 14-inch rims with widths from 3.50 to 4.00 inches and a maximum load capacity of 906 pounds at 30 psi. The narrow wheel-width requirement is especially worth noting when dealing with replacement wheels.

6.50-15 is a bias-ply size used on the 1968 Nissan Patrol and 1968 Peugeot 404. Those are very different vehicles, which makes careful model-based fitment confirmation especially important in this category. No product details are attached here, but the size itself suggests a more utility-oriented 15-inch numeric format than the smaller European passenger-car sizes surrounding it. On a 1968 Nissan Patrol, the use case may lean more toward rugged service than on a 1968 Peugeot 404, so wheel type, tread intent, and overall vehicle setup should be reviewed closely before selecting a product from any neighboring size family.

Rim Diameter: 15 in  ·  Sidewalls: Wide Whitewall, Blackwall

700-15 is a bias-ply size listed for the 1968 Nissan Patrol and supported by a notably broad product mix. Available options include Firestone and BFGoodrich passenger-style tires in blackwall and wide whitewall forms, as well as an STA Traxion blackwall tire with a military and truck attribute. Several listings specify 15-inch rims from 5.00 to 5.50 inches wide and a maximum load capacity of 1700 pounds at 32 psi on certain products. This combination makes 700-15 especially useful for buyers balancing appearance and use case, since the same size can point toward either a classic passenger look or a more utility-focused presentation.

Rim Diameter: 14 in  ·  Sidewalls: Wide Whitewall

H78-14 is a large bias-ply letter-series size used on the 1968 Oldsmobile 88 Series, 1968 Pontiac Catalina, and 1968 Pontiac Pontiac. It belongs to the full-size domestic category and is larger than many common intermediate 14-inch sizes used elsewhere in 1968. The available product is a Coker Classic Bias Ply tire with a 2.50-inch wide whitewall, listed for 14-inch rims from 5.50 to 8.00 inches wide and a maximum load capacity of 1770 pounds at 32 psi. For big GM cars, this size provides a useful combination of substantial load support and a distinctly period full-size sidewall profile.

Rim Diameter: 15 in  ·  Sidewalls: Wide Whitewall, Blackwall

H78-15 is a bias-ply size used on the 1968 Oldsmobile 88 Series and 1968 Toyota Land Cruiser. That unusual overlap means shoppers must be especially careful not to assume identical vehicle needs simply from the size alone. Available products include Coker Classic wide whitewall tires and an STA Traxion blackwall tire with a military and truck attribute. Listed wheel fitments range from 5.50 to 7.00 inches wide, and stated load capacities reach 1830 pounds at 45 psi on the STA product. This is a size where intended use matters, because a full-size passenger car and a utility vehicle may want very different sidewall styles.

J78-14 is a large bias-ply letter-series fitment used on the 1968 Oldsmobile 98 Series and 1968 Pontiac Pontiac. This size sits in the upper end of 14-inch domestic full-size applications and reflects the dimensions needed by heavier late-1960s cars. No product details are attached here, so it serves primarily as a fitment reference. That still matters because it is easy to confuse neighboring H78, J78, and numeric 14-inch sizes when looking at big domestic cars from 1968. Exact model confirmation is the best way to avoid selecting a tire that looks similar but does not match the intended proportions or load range.

Rim Diameter: 15 in  ·  Sidewalls: Dual-White-Stripe, Narrow Whitewall

J78-15 is a large bias-ply 15-inch size used on the 1968 Oldsmobile 98 Series and 1968 Oldsmobile Toronado. This is a substantial domestic fitment for premium and front-drive luxury applications where both load capacity and visual scale matter. Available BFGoodrich Silvertown Classic Bias Ply products include a dual white stripe version and a narrow whitewall version, both specified for 15-inch rims from 5.50 to 7.00 inches wide and carrying a maximum load capacity of 1860 pounds at 32 psi. For a 1968 Oldsmobile in this group, the difference between stripe style and whitewall width can materially affect the finished appearance.

135R14 is a radial size listed specifically for the 1968 Peugeot 204. It is one of the narrowest metric radial sizes represented in the 1968 range and is clearly tied to a light, compact European application. No product details are attached here, so it should be treated as a specialized fitment reference. Because this size is so narrow compared with more common 145R14, 155R13, or 165R14 categories, it is important not to substitute casually. On compact cars like the Peugeot 204, the correct section width can influence both visual balance and the way the car responds on its original wheel size.

G77-14 is a single-application bias-ply size listed for the 1968 Pontiac Tempest. It is a specialized domestic 14-inch fitment and should not be assumed interchangeable with the more commonly seen G78-14 without verifying the exact vehicle setup. No current product details are attached here, so the size primarily acts as an important reference point for Tempest-specific research. For shoppers working through 1968 Pontiac tire fitment, this entry is a good reminder that close-looking letter-series sizes can still be distinct applications. Confirming the exact size associated with the car remains the safest path before evaluating sidewall or brand preferences.

Rim Diameter: 15 in  ·  Sidewalls: Blackwall, Wide Whitewall

145R15 is a radial size listed for the 1968 Renault Renault and supported by a focused group of classic radial products. Available choices include blackwall radials from Firestone and Michelin, along with a BFGoodrich Silvertown Radial wide whitewall option. Product details show 15-inch rim fitment, with stated width ranges from 3.50 to 5.00 inches on some listings and a maximum load capacity of 935 pounds at 44 psi on the Firestone tire. This size is particularly useful for owners who want to preserve the narrow, upright proportions typical of small European 1968 cars while still choosing among different sidewall presentations.

7.10-15/6 is a bias-ply size listed specifically for the 1968 Rover 88. The slash format marks it as a specialized application and separates it from more common passenger-car numeric sizes elsewhere in the 1968 range. No product details are attached here, so its main role is as a precise fitment reference. For a 1968 Rover 88, exact size identification is especially important because nearby Rover listings also include 205R15 on the same model family, showing that even closely related vehicles may be represented through different tire conventions. Wheel type and intended use should both be considered before moving beyond size identification.

5.50-13 is a single-application bias-ply size listed for the 1968 Simca 1000. It represents a compact 13-inch numeric fitment and should be matched carefully rather than generalized to other small European cars from the same year. No product details are attached here, so the entry functions mainly as an exact fitment marker. For owners of a 1968 Simca 1000, this category shows how one model line can sit close to other 13-inch compact sizes while still retaining its own specified dimensions. Verifying the tire size already associated with the vehicle is the most practical first step before comparing any alternate construction format.

5.60-12 is a bias-ply size used on the 1968 Simca 1000 and 1968 Vauxhall Viva. It sits within the small-wheel compact segment of 1968 fitment and reflects the continued use of numeric bias-ply sizing on lightweight economy cars. No product details are attached here, so the size serves mainly as a guide for identifying the correct compact application. On small 12-inch-wheel cars, even slight differences in size can be noticeable in wheelwell clearance and stance. That makes it worth checking the exact model and existing wheel setup rather than assuming any 12-inch bias-ply tire will provide the same fit or appearance.

Rim Diameter: 15 in  ·  Sidewalls: Wide Whitewall, Narrow Whitewall

760-15 is a bias-ply size listed for the 1968 Toyota Land Cruiser and backed by multiple classic-style products. Available choices from BFGoodrich, Coker Classic, and Universal Vintage Tire include wide whitewall and narrow whitewall options, all built around a 15-inch rim diameter. Certain products specify 5.50 to 6.00 inch rim widths and a maximum load capacity of 1710 pounds at 32 psi. Although the Land Cruiser is a utility vehicle, the available sidewall styles show that buyers may be balancing appearance goals with functional needs. Exact wheel setup and intended road use should guide the final decision more than size alone.

Rim Diameter: 14 in  ·  Sidewalls: Narrow Whitewall, Blackwall

700-14 is a bias-ply size used on the 1968 Vauxhall Viscount and 1968 Volkswagen Station Wagon. This shared 14-inch fitment spans two quite different imported vehicle types, making exact model confirmation important before product selection. Available BFGoodrich Silvertown Classic Bias Ply products come in blackwall and narrow whitewall styles, with 14-inch rim fitment specified at 5.00 to 5.50 inches wide and a maximum load capacity of 1360 pounds at 32 psi. For a station wagon or larger European sedan, this size sits in a practical middle zone where both carrying ability and proper vintage proportions deserve attention.

6.15-12 is a single-application bias-ply size listed for the 1968 Vauxhall Viva. It is one of the more specialized small-wheel fitments in the 1968 range and should not be treated as interchangeable with nearby 5.50-12 or 5.60-12 entries without further confirmation. No product details are attached here, so this size serves primarily as a model-specific fitment reference. On compact cars with 12-inch wheels, the exact tire dimensions can influence both appearance and clearance more dramatically than on larger vehicles. That makes it worthwhile to verify the wheel diameter and current tire markings before narrowing any replacement path.

Rim Diameter: 15 in  ·  Sidewalls: Wide Whitewall, Blackwall

600-15 is a bias-ply size used on the 1968 Volkswagen Fastback and 1968 Volkswagen Squareback. It is a classic numeric 15-inch fitment for compact rear-engined applications and offers a distinctly period bias-ply path alongside radial alternatives used elsewhere in the Volkswagen range. Available BFGoodrich Silvertown Classic Bias Ply products include blackwall and wide whitewall versions, with listed 15-inch rim widths from 4.00 to 5.00 inches and a maximum load capacity of 1150 pounds at 32 psi. Because Volkswagen used more than one 15-inch size family in 1968, confirming the exact model is an important first filter.

6.85-15 is a bias-ply size used on the 1968 Volvo 122, 1968 Volvo 142, 1968 Volvo 144, and 1968 Volvo 145. It is a useful example of a size shared across a family of related cars, suggesting a common 15-inch fitment approach within much of the Volvo lineup. No product details are attached here, so the size acts mainly as an application reference. For Volvo owners comparing 6.85-15 with the radial 165R15 also used across several 1968 Volvo models, the key distinction is not just dimensions but also construction character and the type of period look they want the car to present.

7.35-15 is a single-application bias-ply size listed for the 1968 Volvo 122. Within the Volvo range, that makes it a more specialized fitment than the broader 6.85-15 or 165R15 categories. No product details are attached here, so its value lies in identifying the exact tire-size path associated with a particular 1968 Volvo 122 setup. This is an important distinction because owners of similar-looking Volvo cars from the same year may still encounter more than one 15-inch size convention. Before selecting a replacement tire, confirming the current wheel and the exact size associated with the car can help avoid an unnecessary mismatch.
