The 1941 Buick 90 Series sat at the top of Buick’s prewar passenger-car range, known for its long-wheelbase presence, formal styling, and smooth straight-eight character. For collectors restoring one today, tires play a major role in preserving that big Buick look and the way the car presents on the road. The primary fitment is a 750-16 bias-ply tire on a 16-inch rim. Within that size, there is room to choose between traditional blackwall and wide whitewall presentations, along with several period-style bias-ply series. The right choice depends on whether the goal is formal restoration appearance, touring use, or simply staying true to the car’s original-era tire character.
Which Tire Size Is Right for The 1941 Buick 90 Series
The 1941 Buick 90 Series uses one primary tire size: 750-16. It is a bias-ply fitment for a 16-inch rim, and the same size applies to the covered Limited 8 Cyl. sub-model. That means the main decision is less about finding the right size and more about choosing the right bias-ply tire style, sidewall treatment, and product series for your restoration goals and intended road use.
The 750-16 designation is a vintage numeric bias-ply size, with the 7.50 referring to nominal section width in inches and the 16 identifying the wheel diameter. On a 1941 Buick 90 Series, this size preserves the proper prewar tire format and the visual proportion expected on a large formal Buick. Available choices include blackwall and wide whitewall versions from Firestone, Lester, and BFGoodrich, along with several heavier-duty series from STA. It is the right starting point for owners who want the correct size first, then need to sort out appearance, load-oriented construction, and intended use.
Fitment is straightforward for the covered 1941 Buick 90 Series sub-models. Tire selection still matters at the sub-model level because confirming the exact vehicle helps keep the focus on the proper 750-16 bias-ply fitment and the right style of replacement.

1941 Buick 90 Series Limited 8 Cyl.
The 1941 Buick 90 Series Limited 8 Cyl. uses the same 750-16 bias-ply fitment as the core model.

Tire Size & Fitment
What tire size fits a 1941 Buick 90 Series?
The 1941 Buick 90 Series uses a 750-16 tire size. This is a numeric bias-ply fitment used on a 16-inch rim, and it is the primary size associated with the model covered here.
That makes size selection fairly simple, but the next step is still important. A buyer should confirm the wheel diameter on the car, especially if the vehicle has been altered over the years, then choose among the available 750-16 bias-ply options based on appearance, rim-width compatibility, and how the Buick will actually be driven.
What size rim does a 1941 Buick 90 Series use?
The 1941 Buick 90 Series uses a 16-inch rim with its 750-16 tire fitment. Available 750-16 products commonly pair that size with a rim-width range of 5.00 to 6.00 inches.
Rim diameter should be confirmed before any tire purchase, since a 16-inch tire must be mounted on a 16-inch wheel. Width matters as well, particularly on an older collector car that may have replacement wheels, because the right rim dimensions help preserve proper tire shape, clearance, and overall fitment behavior.
Does the 1941 Buick 90 Series Limited 8 Cyl. use the same tire size?
Yes. The 1941 Buick 90 Series Limited 8 Cyl. uses the same 750-16 bias-ply tire size as the core 1941 Buick 90 Series fitment covered here.
Shared fitment makes the search easier because there is no need to sort between multiple primary sizes for this sub-model. The real decision becomes choosing the right type of 750-16 tire, such as blackwall or wide whitewall, and confirming that the wheels on the car still match the expected 16-inch setup.
Choosing the Right Tire
What should I consider when choosing a 750-16 tire for a 1941 Buick 90 Series?
Start with the correct 750-16 size and bias-ply construction, then look at how the Buick will be used and presented. Some 750-16 options are traditional passenger-car tires, while others are heavier-duty products with military or transport-oriented character.
Appearance is a major part of the decision on a prewar Buick, especially when comparing blackwall and wide whitewall choices. It also helps to compare rim-width compatibility, load figures where given, and overall product type so the tire matches the car’s restoration goals rather than simply matching the size.
What sidewall styles are available for 1941 Buick 90 Series tires?
The available 750-16 tires for a 1941 Buick 90 Series include both blackwall and wide whitewall sidewall styles. That gives owners two very different visual directions within the same correct vintage size.
A wide whitewall usually suits a formal prewar luxury-car presentation, while a blackwall creates a more restrained or utility-oriented look. The best choice depends on how the Buick is being restored and which overall appearance the owner wants, since sidewall style can change the character of the car even when the size remains the same.
What brands offer tires for the 1941 Buick 90 Series?
Tires in 750-16 for the 1941 Buick 90 Series are available from Firestone, Lester, BFGoodrich, and STA. Those brands cover both traditional classic-car bias-ply lines and heavier-duty specialty options within the same size.
Brand is only one part of the choice. It still makes sense to compare sidewall style, tire series, rim-width compatibility, and whether the tire is a passenger-car design or a military and truck oriented product, because those differences can matter more than the brand name alone on a large prewar Buick.
Restoration & Appearance
Which tire should I choose for a period-style 1941 Buick 90 Series?
A period-style 1941 Buick 90 Series should begin with the correct 750-16 bias-ply size. From there, traditional passenger-car bias-ply offerings are the most natural path for maintaining the prewar look and stance associated with a large Buick of this era.
The visual finish matters almost as much as the size. Many restorers will focus on whether a blackwall or wide whitewall better suits the car’s intended presentation, while owners pursuing exact historical authenticity should compare their tire choice with marque references, surviving photos, and vehicle-specific documentation before settling on a final appearance.
How does tire construction affect the appearance of a restored 1941 Buick 90 Series?
Tire construction has a visible effect on a restored 1941 Buick 90 Series because a 750-16 bias-ply carries the shape and period presentation expected on a prewar luxury car. The construction is part of the overall visual language, not just a mechanical detail.
That is why many restoration-oriented owners stay with the original-style bias-ply format even before considering brand or sidewall treatment. Once the construction is correct, the remaining appearance choices become more refined, especially when selecting between blackwall and wide whitewall versions to match the car’s desired era-specific personality.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1941 Buick 90 Series?
Yes. A 1941 Buick 90 Series may still call for a 750-16 tire, but aftermarket wheels, different rim widths, suspension work, brake changes, or body alterations can all affect how that size sits and clears on the car.
That is why the actual wheel diameter and width should be checked before choosing among available 750-16 products. Steering clearance, fender space, and overall tire profile should also be reviewed on any modified Buick, since correct size alone does not guarantee the same result once the original wheel or suspension setup has changed.
What should I inspect before driving a 1941 Buick 90 Series on new tires?
Before road use, inspect wheel condition, lug hardware, valve stems, and the general state of the suspension and steering components. The new 750-16 tires should also be checked for proper inflation, even tread seating, and adequate clearance through the full steering range.
A prewar collector car deserves a closer look than a modern daily driver, especially after long storage. Sidewall condition on any older spare, brake operation, wheel bearing health, and signs of rubbing under load are all worth checking so the Buick is ready for actual road miles rather than just garage presentation.
How should 750-16 tires on a collector 1941 Buick 90 Series be maintained?
Maintain 750-16 tires on a collector 1941 Buick 90 Series with regular pressure checks, visual inspections, and careful storage habits. Collector cars often sit for long periods, so tire age, sidewall cracking, flat spotting, and slow air loss deserve more attention than mileage alone would suggest.
Good maintenance also includes keeping the car away from prolonged sunlight, excess heat, moisture, and ozone sources when stored. Before each driving season, inspect tread and sidewalls closely and confirm that the tires still suit the Buick’s current wheel setup, especially if the car has had any wheel, brake, or suspension changes over time.
