The 1941 Oldsmobile 98 Series represented Oldsmobile’s full-size pre-war luxury offering, with substantial styling and road manners that suit a traditional tire presentation. For many owners, the appeal lies in preserving that long, formal look while keeping the car ready for careful road use. This Oldsmobile uses a 700-15 bias-ply tire on a 15-inch rim, so the main fitment decision is less about size and more about selecting the right type of bias-ply tire within that format. Available choices include blackwall and wide whitewall styles, along with passenger-oriented and more utility-focused series. That makes wheel verification, intended use, and restoration priorities especially important before choosing a set.
Which Tire Size Is Right for The 1941 Oldsmobile 98 Series
The 1941 Oldsmobile 98 Series uses one primary tire size: 700-15, a bias-ply fitment for a 15-inch rim. The 8 Cyl. sub-model uses that same size, so the key choice is not between multiple fitments but between sidewall style, tire series, and how closely the tire’s appearance and character suit a restoration-minded car or a more general road-use setup.
A 700-15 tire uses the vintage numeric bias-ply sizing system, where the 700 indicates an approximate 7.00-inch nominal section width and the 15 identifies the rim diameter in inches. On the 1941 Oldsmobile 98 Series, that format matches the car’s original-era bias-ply character and visual proportions. Within this size, choices include Firestone, BFGoodrich, and STA products, with blackwall and wide whitewall options as well as several different tire series. The right selection depends on whether the priority is a more traditional passenger-car appearance or a more utility-oriented bias-ply tire in the same basic size.
Tire fitment is straightforward for the covered 1941 Oldsmobile 98 Series sub-models. The main value in checking the sub-model is simply confirming that the car remains on the expected 15-inch wheel and 700-15 bias-ply fitment before comparing sidewall and series options.

Tire Size & Fitment
What tire size fits a 1941 Oldsmobile 98 Series?
The 1941 Oldsmobile 98 Series uses a 700-15 tire size. This is a bias-ply fitment built for a 15-inch rim, and it is the primary size associated with the model covered here, including the 8 Cyl. sub-model.
That means the main buying decision is not sorting through multiple primary sizes, but choosing the right 700-15 tire for the car’s appearance and use. Before replacing tires, confirm that the wheels on the car are still the correct diameter and have not been changed over the years through aftermarket or later-service substitutions.
What size rim does a 1941 Oldsmobile 98 Series use?
The 1941 Oldsmobile 98 Series uses a 15-inch rim with its 700-15 tire fitment. Available 700-15 products commonly pair that size with a 5.00- to 5.50-inch rim width range where that specification is stated.
Rim diameter should always be verified directly on the car before mounting new tires, especially on a vehicle that may have seen decades of service work. A matching 15-inch diameter is essential, and wheel width should also be checked if the car no longer has its original-style wheels or has been fitted with replacements from another application.
Does the 1941 Oldsmobile 98 Series 8 Cyl. use the same tire size?
Yes. The 1941 Oldsmobile 98 Series 8 Cyl. uses the same 700-15 bias-ply tire size as the model fitment covered here. That keeps the size question simple and leaves appearance and tire type as the next decisions.
Even when the size stays consistent across the sub-model, it still helps to inspect the actual wheel and tire setup on the car. Collector vehicles are often changed during restoration or long-term ownership, so confirming the wheel diameter, wheel width, and overall clearance remains worthwhile before settling on a specific 700-15 product.
Choosing the Right Tire
What should I consider when choosing a 700-15 tire for a 1941 Oldsmobile 98 Series?
Start with the correct primary size, which is 700-15, and stay mindful that this Oldsmobile uses a bias-ply tire format. From there, compare whether the tire’s style and series better suit a restoration-oriented passenger-car appearance or a more utility-focused application in the same size.
Sidewall treatment is a major part of the decision because wide whitewall and blackwall versions create very different visual results on a pre-war full-size Oldsmobile. It also helps to review rim-width compatibility where stated, along with any load figures attached to a given tire, so the final choice suits both the wheel and the car’s intended use.
What sidewall styles are available for 1941 Oldsmobile 98 Series tires?
The available 700-15 tires for the 1941 Oldsmobile 98 Series include blackwall and wide whitewall sidewall styles. Those choices give the car either a more restrained service look or a more formal, restoration-oriented presentation that better matches many full-size pre-war cars.
The sidewall decision matters because it changes the car’s visual balance almost as much as the wheel itself. A wide whitewall can emphasize the period character of the Oldsmobile, while a blackwall can suit a plainer or more utility-minded look. Either way, the tire still needs to remain the proper 700-15 bias-ply fitment for the vehicle.
What brands offer tires for the 1941 Oldsmobile 98 Series?
700-15 tires for the 1941 Oldsmobile 98 Series are available from Firestone, BFGoodrich, and STA. Those options include traditional passenger-style bias-ply tires as well as several utility-oriented series in the same basic size and construction family.
Choosing among brands should come down to the tire’s specific style, series, and intended use rather than the name alone. A Firestone or BFGoodrich wide whitewall may appeal to a restoration-focused owner, while certain STA products lean toward military, truck, or transport-style character. Matching the tire to the car’s presentation is usually the most useful approach.
Restoration & Appearance
Which tire should I choose for a period-style 1941 Oldsmobile 98 Series?
A period-style starting point for the 1941 Oldsmobile 98 Series is a 700-15 bias-ply tire, since that size and construction match the car’s established fitment. Within that size, a traditional passenger-car bias-ply with an appearance that suits a large pre-war Oldsmobile is usually the most natural direction.
The exact sidewall look matters just as much as the size because it shapes the car’s overall stance and visual authenticity. Wide whitewall and blackwall options create different restoration results, so owners pursuing strict originality should compare the car against period photos, marque-club guidance, or other vehicle-specific historical references before making a final appearance choice.
Does correct tire fitment matter for a 1941 Oldsmobile 98 Series restoration?
Yes. Correct tire fitment matters on a 1941 Oldsmobile 98 Series because tire size and construction strongly influence the car’s stance, proportions, and period character. A 700-15 bias-ply setup preserves the visual relationship between the wheel opening, sidewall profile, and overall pre-war presentation.
Restoration quality is not only about appearance, though. The wheel diameter and width still need to match the tire, and the condition of the rims should be checked before mounting new rubber. Even a visually appropriate tire can be the wrong choice if the car has altered wheels, changed suspension height, or unresolved clearance issues from earlier work.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1941 Oldsmobile 98 Series?
Yes. Modifications can affect tire fitment on a 1941 Oldsmobile 98 Series even when the intended tire size remains 700-15. Wheel changes, altered ride height, brake conversions, or body and suspension work can all change the space available around the tire.
A car from this era may also have replacement wheels installed at some point in its life, so it is wise to confirm actual rim diameter and wheel width before mounting new tires. Steering clearance and fender clearance should be checked as well, particularly if the car no longer sits at its original height or uses non-original wheel hardware.
What should I inspect before driving a 1941 Oldsmobile 98 Series on new tires?
Before road use, inspect the wheels, valve stems, and overall tire mounting, and make sure the 700-15 tires are seated properly on the 15-inch rims. It also helps to verify inflation, lug tightness, and general clearance at the front and rear before the car is driven any distance.
A pre-war car deserves a broader once-over beyond the tires alone. Check for rubbing during slow steering movement, look over suspension and steering condition, and inspect for any signs that the car sits unevenly. A short initial test drive followed by another visual inspection can reveal clearance or settling issues before a longer outing.
How should 700-15 tires on a collector 1941 Oldsmobile 98 Series be maintained?
700-15 tires on a collector 1941 Oldsmobile 98 Series should be inspected regularly for pressure loss, tread wear, sidewall cracking, cuts, bulges, and signs of long-term aging. Because collector cars are often driven less, condition over time matters just as much as mileage.
Storage habits also affect tire life on a large pre-war car. Keeping the Oldsmobile away from prolonged sunlight, excess heat, moisture, and ozone sources can help preserve the tires between drives. Periodic checks remain important even when the car is seldom used, since age-related deterioration can develop long before the tread appears worn.
