1968 Chevrolet Tire Fitment Guide

1968 Chevrolet vehicles use 11 different bias-ply sizes across seven model lines: 735-14, 775-14, F70-14, 825-14, G70-14, 855-14, 8.25-15, E70-14, 700-13, F70-15, and G70-15. Camaro uses 735-14, 775-14, and F70-14; Chevelle uses 735-14, 775-14, 825-14, and G70-14; full-size Chevrolet uses 825-14, 855-14, and 8.25-15; Chevy II uses 735-14 and E70-14; Corvair uses 700-13; Corvette uses F70-15; and Impala uses 8.25-15 and G70-15.

The practical takeaway is that 1968 Chevrolet fitment starts with model identification, then wheel diameter. Corvair is on 13-inch tires, most Camaro, Chevelle, Chevy II, and some full-size applications are on 14-inch tires, while Corvette and some big-car applications move to 15-inch sizes. Rim width guidance also changes by size, from 4.00 to 5.00 inches for 700-13 up to 5.50 to 8.00 inches on several 15-inch performance sizes, so the actual wheel should be checked before choosing a tire.

On a 1968 Chevrolet tire, 735-14 is a numeric bias-ply size. The first number represents the nominal section width, read as 7.35 inches, and the second number is the wheel diameter in inches, which is 14. That size appears on certain Camaro, Chevelle, and Chevy II applications and is offered with 14-inch fitment and rim width guidance of 5.00 to 5.50 inches.

Numeric sizing is common on 1960s American cars and usually signals a more traditional stock-style fitment rather than a later muscle-car letter-series look. For a 1968 Chevrolet owner, seeing 735-14 on the car or in factory literature points you toward a period bias-ply replacement with relatively straightforward sidewall choices such as blackwall or narrow whitewall, rather than redline or raised white letter performance styling.

On a 1968 Chevrolet tire, F70-14 is an alphanumeric bias-ply size. The letter-and-number combination identifies the tire's relative profile family within the older U.S. sizing system, while the 14 confirms a 14-inch wheel diameter. In 1968 Chevrolet applications, F70-14 belongs to Camaro and uses a wider performance-oriented presentation than the smaller numeric sizes.

That older alphanumeric format matters because it usually corresponds with the late-1960s muscle era, when redlines, pin white stripes, and raised white letters became part of the car's personality as much as the wheel itself. If your 1968 Chevrolet Camaro calls for F70-14, you are generally choosing a tire for visual character and period performance appearance, not simply translating it into a smaller stock-style whitewall replacement.

No, 1968 Chevrolet models do not use the same tire size. The range spans compact 700-13 Corvair fitment, multiple 14-inch numeric and alphanumeric sizes for Camaro, Chevelle, Chevy II, and some full-size cars, and 15-inch sizes for Corvette, Impala, and selected full-size Chevrolet applications. Even within the same wheel diameter, the size can change significantly from one model to another.

That means a buyer should not rely on year and make alone when replacing tires on a 1968 Chevrolet. A Chevelle and a Camaro may both use 14-inch wheels, yet they can still call for different section widths and different sidewall treatments depending on the car's role and visual intent. Confirming the exact model before moving to brand or sidewall preference prevents an otherwise correct-looking tire from being the wrong fitment.

1968 Chevrolet tires are available in several period-correct sidewall styles, and the exact choice depends on size. Across the range, available styles include blackwall, narrow whitewall, wide whitewall, redline, pin white stripe, and raised white letter. Smaller stock-style numeric sizes such as 735-14, 775-14, 825-14, and 855-14 lean toward blackwall or whitewall treatments, while many F70-, G70-, and E70-series sizes carry the sportier redline, stripe, or raised white letter look associated with late-1960s performance Chevrolets.

For a restoration-minded owner, sidewall style is often as important visually as the size itself. Full-size Chevrolet and many mainstream passenger-car applications generally look most natural with blackwall or whitewall tires, while Camaro, Chevelle SS-era, Chevy II performance, Corvette, and some Impala combinations often suit redlines, pin stripes, or raised white letters. The best approach is to match the sidewall to the character of your specific 1968 Chevrolet rather than treating every size as visually interchangeable.

BFGoodrich, Firestone, Goodyear, and US Royal all have coverage within the 1968 Chevrolet tire range. BFGoodrich appears strongly in the numeric 14-inch sizes such as 735-14, 775-14, 825-14, and 855-14. Firestone and Goodyear dominate many of the alphanumeric muscle-era sizes including E70-14, F70-14, F70-15, G70-14, and G70-15, while US Royal appears in 775-14 narrow whitewall form.

Brand choice on a 1968 Chevrolet often comes down to the look you want as much as the size you need. Owners restoring a more conservative family Chevrolet may focus on whitewall or blackwall offerings, while those working with Camaro, Chevelle, Corvette, or sportier Impala applications may gravitate toward Wide Oval or Custom Wide Tread style offerings that better match the visual language of the era. Start with correct size, then narrow by sidewall and brand character.

On several 1968 Chevrolet alphanumeric sizes, Firestone and Goodyear overlap but do not mirror each other exactly. Firestone offers F70-14, E70-14, G70-14, F70-15, and G70-15 in multiple sidewall styles, while Goodyear appears in those same families with narrower product selections depending on the size. Rim width ranges are also not always identical: for example, Firestone F70-14 uses 6.00 to 7.00-inch rims, while the Goodyear F70-14 uses 6.0 to 7.0 inches; Firestone G70-14 uses 6.50 to 7.00 inches, while the Goodyear G70-14 stretches from 6.0 to 8.0 inches.

Those differences matter most when your 1968 Chevrolet already has a specific wheel width and you want the tire to sit correctly on it. A buyer choosing between brands in the same nominal size should compare rim-width compatibility first, then decide whether the available sidewall style matches the car's intended appearance. It is less about one brand being universally preferable and more about finding the version that best suits your exact wheel and the visual finish you want on the car.

Rim width requirements for 1968 Chevrolet tires vary by size. 700-13 uses 4.00 to 5.00 inches, 735-14 uses 5.00 to 5.50, 775-14 runs from 5.00 to 6.00 depending on the tire, 825-14 uses 5.00 to 6.00, 855-14 uses 5.50 to 6.00, E70-14 and F70-14 typically use 6.00 to 7.00, G70-14 ranges from 6.0 to 8.0 depending on brand, and F70-15 and G70-15 span 5.50 to 8.00 inches depending on the product.

That spread shows why matching tire size to the actual wheel matters on a 1968 Chevrolet, especially when a car has been restored with aftermarket wheels or mixed parts from another model. A Camaro or Chevelle wearing a wider performance wheel may be better suited to an alphanumeric size than a narrow stock numeric fitment, while a full-size Chevrolet with stock steel wheels may call for a more traditional width. Always compare the wheel you have to the rim-width range for the exact tire size you want.

The 1968 Chevrolet products here do not show tube-type or tubeless markings in the size descriptions, so tube choice should be treated as dependent on the specific tire and, just as importantly, the wheel itself. Bias-ply collector tires can be used in tube-type or tubeless contexts depending on casing design and the construction of the wheel they are mounted on. That matters most on older wheels that may not have the same bead-seat condition or sealing characteristics as a modern rim.

For a 1968 Chevrolet owner, the practical move is to confirm tube use before mounting rather than assuming every bias-ply tire follows the same rule. A restored steel wheel, a wheel with pitting, or a wheel intended for tube service may call for a different setup than a fresh, airtight rim. If originality matters, verify what is appropriate for your specific wheel style and tire choice before final installation, especially on cars that sit for long periods between drives.

No single original wheel works across all 1968 Chevrolet tire sizes because the range spans 13-inch, 14-inch, and 15-inch applications. A Corvair wheel for 700-13 is not interchangeable with a Camaro F70-14 setup, and a Corvette or Impala 15-inch application requires a different diameter wheel than most 14-inch passenger-car sizes. Even among same-diameter tires, rim width requirements can differ enough to matter.

Within a given model, some size changes may still remain compatible if the wheel diameter matches and the rim width falls inside the approved range for the tire. That is most relevant on performance-oriented 14-inch and 15-inch Chevrolet applications, where sidewall style and section width vary more than wheel diameter. Before reusing original 1968 Chevrolet wheels with a different size, confirm both the wheel diameter and its actual width rather than assuming all factory wheels of the same era are equivalent.

A 1968 Chevrolet should be stored in a cool, dry space away from direct sunlight, electric motors, welders, battery chargers, and other ozone sources that accelerate sidewall aging. Bias-ply tires are particularly sensitive to long static periods, and they can develop temporary flat-spotting more readily than modern radials after the car sits. Keeping the car on clean, dry flooring and maintaining proper inflation helps reduce casing stress during storage.

For seasonal or long-term storage, roll the 1968 Chevrolet periodically or place it on stands if the car will remain parked for an extended period and the suspension setup allows it. Tire covers can help block light, and a quick pressure check before and after storage is worthwhile. Collector cars often age out their tires before they wear them out, so storage habits play a major role in how well a set remains usable and presentable.

Tires on a 1968 Chevrolet are usually judged more by age than by mileage, especially on collector vehicles that may only see occasional weekend use. A good rule is to inspect them closely once they are five to seven years old and to give serious replacement consideration as they approach ten years, even if tread depth still looks strong. The DOT date code on the tire sidewall remains the best age reference when you are evaluating an existing set.

That timeline matters because a 1968 Chevrolet may spend much of its life parked, transported to shows, or driven only in fair weather, which can hide aging until cracks, hardening, or loss of flexibility become obvious. A tire that still looks attractive on a show field may no longer be the right choice for regular road use. When in doubt, age should outweigh appearance alone, particularly before higher-speed or longer-distance driving.

Tires on a 1968 Chevrolet should be inspected before every drive and again before any longer outing. Look for sidewall cracking, tread separation, punctures, bulges, uneven wear, and pressure loss. Because these are bias-ply applications and some cars may use older wheels or tube-based setups, it is also wise to pay attention to valve-stem condition and how consistently each tire holds air between drives.

Frequent inspection is especially important on collector Chevrolets because many spend weeks or months parked between short trips. A problem that develops quietly in storage can show up the moment the car returns to road speed. Make tire inspection part of a larger pre-drive habit that includes checking wheel hardware, brakes, steering response, and the spare, particularly before a tour, interstate trip, or club event that puts more sustained load on the car than a local cruise.

A 1968 Chevrolet Camaro would originally have been equipped with bias-ply tires, which is consistent with the sizes used across the Camaro range here: 735-14, 775-14, and F70-14. The exact size depended on the specific configuration and how the car was positioned, from standard passenger use to more performance-oriented applications. Sidewall appearance could also vary, with plain blackwall or whitewall treatments on some combinations and more aggressive muscle-era styling on others.

For a restoration, the safest path is to match the car's actual wheel diameter first and then narrow the choice by the way the car was originally equipped or the way you intend to present it. Because 1968 Chevrolet could vary by market, equipment level, and appearance package, marque clubs, factory literature, and survivor-car research remain the best tie-breakers when two period-correct bias-ply options both seem plausible for your Camaro.

Correct tire fitment absolutely matters when a 1968 Chevrolet is judged for authenticity. Size, construction type, wheel diameter, and sidewall style all affect whether the car looks period-correct, and judges or knowledgeable enthusiasts will often notice if a Corvair wears the wrong diameter, a full-size Chevrolet carries an overly sporty sidewall, or a muscle-era model uses a style that does not match its presentation. Bias-ply construction is especially important for an originality-focused car from 1968.

The practical question is not only whether the tire fits, but whether it fits the story your 1968 Chevrolet is meant to tell. A stock family sedan and a big-block-style performance build can both be correct in very different ways. If your car is headed for marque judging, review event rules and compare your intended tire size and sidewall treatment against known period examples so the final choice supports, rather than undermines, the restoration.

On a 1968 Chevrolet, stock-style whitewall tires generally appear in the numeric sizes such as 735-14, 775-14, 825-14, 855-14, and 700-13, while redline, pin white stripe, and raised white letter treatments appear mainly on E70-, F70-, and G70-series performance-oriented sizes. Both are bias-ply, but they convey very different period identities. Whitewalls suit mainstream passenger-car presentation, while redlines and raised white letters align more closely with late-1960s performance imagery.

That distinction matters in restoration because a technically correct wheel diameter alone does not guarantee an authentic result. A wide whitewall on a Corvair can look exactly right, while the same visual treatment might look out of place on a 1968 Chevrolet muscle application that is better served by an alphanumeric tire with redline or RWL styling. Choosing between them is often as much about historical appearance as it is about fitment.

1968 Chevrolet tires can be suitable for highway driving when they are the correct size, properly mounted, correctly inflated, and in sound condition. Every size here is bias-ply, so road feel, tracking, and breakaway characteristics will differ from modern radial behavior. No speed rating markings appear in these size descriptions, which means the owner's judgment and the overall condition of the tire, wheel, suspension, and alignment matter more than relying on a modern speed-letter shorthand.

For most normal highway use, the broader mechanical condition of a 1968 Chevrolet is often just as important as the tire itself. Brake performance, steering play, suspension wear, and the car's age should all shape how fast and how far you drive. A freshly restored Corvette, Camaro, or Impala on correct bias-ply tires may be very enjoyable on the road, but it should still be driven with the manners and limits appropriate to a 1968 vehicle.

Several 1968 Chevrolet sizes carry load figures tied to 32 psi. Examples include 735-14 at 1,360 pounds at 32 psi, 775-14 at 1,580 pounds at 32 psi, 825-14 and G70-14 at 1,620 pounds at 32 psi, 855-14 at 1,740 pounds at 32 psi, E70-14 at 1,400 pounds at 32 psi, 700-13 at 1,270 pounds at 32 psi, F70-14 and F70-15 at 1,500 pounds at 32 psi, and G70-15 at 1,620 pounds at 32 psi. Those figures are tire ratings, not universal vehicle inflation recommendations.

For an actual 1968 Chevrolet, start with the factory recommendation in the owner's manual or on the vehicle information sources appropriate to the car, then make sure your chosen tire's pressure and load capability align with that use. Do not transfer a pressure from one size to another simply because both fit Chevrolets from the same year. Full-size cars, compact cars, and performance models can place very different demands on what appears to be a similar-looking bias-ply tire.

Before taking a 1968 Chevrolet on a longer drive, inspect each tire for cracks, cuts, bulges, punctures, irregular wear, and correct cold inflation pressure. Check that the valve stems are sound, the wheels are secure, and the spare is usable and inflated. On a collector car running older-style bias-ply tires, it is also smart to note whether the car has developed any vibration, pull, or flat-spot sensation since its last outing.

Tires are only one part of the preparation, but they are one of the most visible and load-sensitive parts of the car. A longer trip in a 1968 Chevrolet should also include a quick review of brakes, steering, fluid levels, belts, hoses, and lighting so the car is ready for sustained use rather than a short local cruise. That extra check is especially valuable if the car has spent extended time parked or has recently returned from restoration work.
