The 1968 Volvo 145 brought Volvo’s practical wagon formula into the long-roof 140-series era, pairing crisp Scandinavian design with the durability and everyday usefulness that still make these cars appealing to enthusiasts. Because the car sits at the crossroads between period bias-ply fitment and later radial thinking, tire choice matters as much for character as for road manners. This Volvo 145 uses either a 165R15 radial or a 6.85-15 bias-ply on a 15-inch rim. Available choices include blackwall, narrow whitewall, and wide whitewall styles across several vintage and classic radial lines. The right pick depends on whether the goal is preservation-minded appearance, more modern road use, or a careful balance of both.
Which Tire Size Is Right for The 1968 Volvo 145
The 1968 Volvo 145 uses two primary tire sizes, and the difference is construction rather than wheel diameter, since both fit a 15-inch rim. The first step is deciding whether the car is being kept with its period-style 6.85-15 bias-ply fitment or fitted with the 165R15 radial alternative used on the same model. Once that is settled, the decision shifts to sidewall style, tire series, and wheel-width compatibility.
165R15 is a Euro-metric radial size in which 165 refers to the nominal section width in millimeters, R identifies radial construction, and 15 is the rim diameter in inches. On a 1968 Volvo 145, this size gives the buyer a true radial-format option while keeping the correct 15-inch wheel diameter. It is available in several classic radial lines from brands such as Coker Classic, American Classic, Firestone, BFGoodrich, Michelin, and Vredestein, with blackwall, narrow whitewall, and wide whitewall presentations. This size makes sense for owners focused on a traditional radial fitment with a choice of appearance and driving-purpose emphasis.
6.85-15 is a numeric bias-ply size in which 6.85 refers to the nominal section width in inches and 15 identifies the rim diameter. That sizing language is typical of period bias-ply fitments and suits a 1968 Volvo 145 owner who wants to stay closer to an earlier tire construction style. Its significance is less about modern metric sizing and more about preserving the vintage look and feel associated with bias-ply tires on a 15-inch wheel. This size is the one to evaluate when restoration character and traditional presentation matter more than moving to a radial-format tire.
Sub-model fitment is straightforward here because the covered Volvo 145 wagon configuration uses the same two 15-inch tire-size paths. Checking the exact sub-model still matters so the tire choice stays aligned with the car’s construction preference, wheel setup, and restoration direction.

Tire Size & Fitment
What tire size fits a 1968 Volvo 145?
A 1968 Volvo 145 uses two primary tire sizes: 165R15 in radial construction and 6.85-15 in bias-ply construction. Both sizes are tied to the same 15-inch wheel diameter, so the fitment decision is centered on construction type and the kind of driving or presentation the car is meant to have.
That means the real choice is not simply width or rim size. A buyer should first confirm whether the Volvo is being kept in a restoration-oriented, bias-ply direction or moved to a radial setup, then verify the actual wheel width on the car before selecting among available blackwall, narrow whitewall, or wide whitewall options.
What size rim does a 1968 Volvo 145 use?
The 1968 Volvo 145 uses a 15-inch rim with either of its primary tire sizes. Both the 165R15 radial and the 6.85-15 bias-ply share that rim diameter, which simplifies the basic wheel-diameter question even though the tire constructions differ.
Rim diameter is only part of the check, especially on an older wagon that may have had wheel changes over time. Measuring the wheel’s actual width is important before choosing among the available 165R15 radials, because approved rim-width ranges vary by product and can influence which tire is the better match for the car’s current setup.
What does 6.85-15 mean on a 1968 Volvo 145?
On a 1968 Volvo 145, 6.85-15 is a vintage numeric bias-ply size. The 6.85 refers to the tire’s nominal section width in inches, while the 15 refers to the rim diameter in inches. It is an older sizing format that predates modern metric radial conventions and is closely associated with period bias-ply fitment.
For the owner, that matters because 6.85-15 is not just another way of writing a radial size. It signals a different construction style, different visual character, and a different buying decision than a 165R15 radial. Before choosing it, confirm that the car’s wheels and restoration goals still point toward a bias-ply tire rather than a radial-format alternative.
Choosing the Right Tire
What should I consider when choosing a 165R15 tire for a 1968 Volvo 145?
Choosing a 165R15 for a 1968 Volvo 145 starts with confirming that the car is being set up for a radial tire rather than the alternate 6.85-15 bias-ply fitment. From there, compare the tire’s approved rim-width range, sidewall style, load figure where stated, and the overall character of the radial series being considered.
The available 165R15 range is broad enough that appearance and intended use become important. A blackwall radial may suit a more understated driver, while narrow or wide whitewalls can shift the car toward a more stylized vintage presentation. Wheel width, ride-height changes, and the kind of road use the wagon sees should all be checked before making a final selection.
What sidewall styles are available for 1968 Volvo 145 tires?
For the 1968 Volvo 145, the available 165R15 radial products include blackwall, narrow whitewall, and wide whitewall sidewall styles. That gives the car a meaningful appearance choice without changing the basic 15-inch radial size, and it lets the owner tailor the tire’s visual presence to the wagon’s restoration or driving style.
Sidewall style can noticeably change how a vintage Volvo presents, especially on a wagon with a clean, upright body shape. The choice should still stay secondary to correct size, construction, and wheel compatibility. Once those basics are confirmed, the sidewall becomes a useful way to lean the car toward a restrained European look or a more traditional restoration-oriented presentation.
What brands offer tires for the 1968 Volvo 145?
In 165R15 radial fitment, the 1968 Volvo 145 has options from Coker Classic, American Classic, Firestone, BFGoodrich, Michelin, and Vredestein. Those choices appear across several tire series, including Coker Classic Radial, Star Series, F560 Radial, Silvertown Radial, Michelin XZX, Michelin XAS, Snow Classic, and Sprint Classic.
Brand alone should not be the only deciding factor. It is smarter to compare each tire’s sidewall treatment, approved rim-width range, and overall intended character, then match those details to how the Volvo is actually used. A buyer restoring the car’s visual period feel may choose differently than an owner who wants a blackwall radial for regular fair-weather driving.
Restoration & Appearance
Which tire should I choose for a period-style 1968 Volvo 145?
A period-style 1968 Volvo 145 usually starts with deciding whether the car should retain the 6.85-15 bias-ply look and feel or use the 165R15 radial size while staying within a vintage-appropriate overall presentation. Both paths can support an older Volvo’s character, but they create different visual and driving impressions.
For a restoration-minded choice, construction matters as much as sidewall style. Bias-ply generally preserves a more traditional presentation, while a 165R15 radial can keep the car visually restrained with blackwall or add whitewall treatment for a more styled look. When exact originality matters, compare the tire choice against marque references and the car’s own historical details.
How does tire construction affect the appearance of a restored 1968 Volvo 145?
On a restored 1968 Volvo 145, tire construction affects both stance and visual character. A 6.85-15 bias-ply tends to support a more traditional vintage presentation because the size format itself belongs to the period, while a 165R15 radial gives the car a later, more modernized tire language even when the wheel diameter stays the same.
That difference is especially noticeable once sidewall treatment is added. Blackwalls keep the look simple and understated, while narrow or wide whitewalls shift the car toward a stronger classic-car impression. Buyers trying to balance authenticity, appearance, and road use should settle the construction question first, then use sidewall style and tire series to fine-tune the finished look.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1968 Volvo 145?
Modifications can absolutely affect tire fitment on a 1968 Volvo 145, even when the car is using the correct nominal size. Aftermarket wheels, changes in wheel width, suspension alterations, lowering, or body and fender work can all change how much clearance the tire has during steering and suspension movement.
That is especially important when choosing among 165R15 radial products, because approved rim-width ranges are not identical across every option. A wagon that still has stock-style wheels may accept a wider range of choices than one that has been altered over the years. Checking wheel dimensions and clearance at full steering lock is a smart step before final tire selection.
What should I inspect before driving a 1968 Volvo 145 on new tires?
Before driving a 1968 Volvo 145 on new tires, inspect the wheels for correct diameter and width, confirm that the tire is seated properly, and set inflation pressure to the tire and vehicle requirements being used. It also helps to check for brake drag, loose wheel hardware, and any obvious steering or suspension wear.
Older cars often reveal other issues once fresh tires are installed. Side-to-side clearance, front-end alignment condition, and the car’s response over bumps should all be watched on the first drives. A quick recheck after a short shakedown run can catch rubbing, unusual wear patterns, or air loss early before the Volvo is taken on a longer outing.
How should 165R15 tires on a collector 1968 Volvo 145 be maintained?
165R15 tires on a collector 1968 Volvo 145 should be maintained with regular pressure checks, visual inspections for cracking or bulges, and periodic examination of tread wear and air retention. Because collector cars often sit for long periods, condition matters just as much as mileage, and stored tires deserve routine attention even when the wagon is not driven often.
Storage habits make a real difference on a vintage Volvo. Keeping the car away from prolonged sunlight, excess heat, moisture, and ozone-producing equipment helps preserve the rubber, and moving the vehicle occasionally can reduce long stationary loading. Before each driving season, inspect valve stems, confirm wheel condition, and look closely for any age-related changes in the sidewalls.
