The 1932 Buick 90 Series belongs to Buick’s early Depression-era luxury class, when large straight-eight automobiles still carried substantial weight, presence, and road-car dignity. Buyers restoring or maintaining one today usually care as much about stance and visual authenticity as they do about safe road use. This Buick uses a 700-18 bias-ply tire on an 18-inch rim, which makes construction and presentation central to the selection process. Available choices include traditional blackwall styles along with whitewall and double-whitewall offerings in period-style series. For a careful restoration or a drivable collector car, the goal is matching the Buick’s size, wheel setup, and intended appearance before putting it back on the road.
Which Tire Size Is Right for The 1932 Buick 90 Series
The 1932 Buick 90 Series uses one primary tire size: 700-18, a bias-ply tire designed for an 18-inch rim. The same size is used on the covered 8 Cyl. sub-model, so the main decision is not which primary size fits, but which period-style tire, sidewall treatment, and series best suits the Buick’s restoration goals and road-use plans.
A 700-18 size uses the vintage numeric bias-ply system, where the 700 indicates an approximate 7.00-inch nominal section width and the 18 identifies the rim diameter in inches. On the 1932 Buick 90 Series, this is a traditional bias-ply fitment that matches the vehicle’s era and preserves the tall, upright tire look associated with full-size early-1930s automobiles. Within this size, choices include Firestone, Lester, Excelsior, and STA offerings, with blackwall, wide whitewall, and double-whitewall presentations across several tire series. That makes 700-18 the key starting point whether the priority is a restoration-oriented appearance, a more utilitarian look, or confirming wheel compatibility on an older collector car.
Tire fitment is straightforward for the covered 1932 Buick 90 Series sub-models because the same primary size is used throughout. Checking the exact sub-model still matters, but the selection focus remains on the correct 700-18 bias-ply size and the tire style that suits the car’s intended presentation.

1932 Buick 90 Series 8 Cyl.
The 1932 Buick 90 Series 8 Cyl. uses the same 700-18 bias-ply fitment as the model core, so the main concern is choosing the right tire within that size rather than sorting through multiple primary fitments. That keeps the decision centered on period-style appearance, wheel compatibility, and whether blackwall, whitewall, or double-whitewall best matches the vehicle.
The tire sizes listed on this page assume factory-standard vehicle configuration. The following modifications may affect tire fitment and are not reflected in this guide:
Suspension changes (lowering, lift kits, spring replacements)
Body alterations (fender modifications, custom bodywork)
If your vehicle has been modified from factory specifications, verify tire clearance before purchase.

Tire Size & Fitment
What tire size fits a 1932 Buick 90 Series?
The 1932 Buick 90 Series uses a 700-18 tire. This is a vintage numeric bias-ply size designed for an 18-inch rim, and it is the primary fitment for the covered vehicle configuration, including the 8 Cyl. sub-model.
The practical decision is choosing the right 700-18 tire within that fitment rather than searching for multiple primary sizes. Sidewall style, tire series, and wheel compatibility all matter, especially on an older collector car where original-style wheels, replacement rims, or long-ago modifications may affect what should go back on the vehicle.
What size rim does a 1932 Buick 90 Series use?
The 1932 Buick 90 Series uses an 18-inch rim with its 700-18 tire size. Product offerings in this fitment also show that rim-width compatibility can vary by tire design, even though the basic rim diameter remains the same.
Confirming diameter is only the first step on a car of this age. The actual wheel on the Buick should also be checked for width and condition before mounting tires, because some 700-18 products are built around narrower vintage passenger-car rims while others are intended for different wheel-width ranges and visual purposes.
Does the 1932 Buick 90 Series 8 Cyl. use the same tire size?
Yes. The covered 1932 Buick 90 Series 8 Cyl. uses the same 700-18 bias-ply tire size as the model core. That keeps fitment simple at the size level and avoids the need to sort between multiple primary diameter groups.
Even with shared size fitment, tire choice still affects how the car looks and how closely it matches a restoration goal. A blackwall, wide whitewall, or double-whitewall 700-18 can change the Buick’s presentation noticeably, so the better question becomes which version of the correct size belongs on the particular car you are building or maintaining.
Choosing the Right Tire
What should I consider when choosing a 700-18 tire for a 1932 Buick 90 Series?
Start with the correct 700-18 size and its bias-ply construction, since that is the primary fitment for the 1932 Buick 90 Series. From there, compare the tire’s intended character, sidewall treatment, rim-width compatibility, and whether the design suits a restoration-oriented luxury car or a more utility-focused presentation.
Brand and tire series also help narrow the choice. Some 700-18 options emphasize traditional blackwall styling, while others offer wide whitewall or double-whitewall looks that can better suit an upscale early-1930s Buick. The right selection depends on wheel setup, appearance goals, and how the vehicle will actually be driven once completed.
What sidewall styles are available for 1932 Buick 90 Series tires?
The 1932 Buick 90 Series has 700-18 tire options in blackwall, wide whitewall, and double-whitewall styles. Those choices let the owner keep a restrained service look or move toward a more formal period-style appearance that better complements a large Buick from the early 1930s.
Sidewall style changes appearance much more than fitment, but it should still be chosen carefully. A whitewall treatment can be appropriate for a restoration-oriented presentation, while a blackwall may suit a driver or a less ornate look. If authenticity is important, compare the tire choice with period photos or Buick-specific restoration references before deciding.
What brands offer tires for the 1932 Buick 90 Series?
The 700-18 fitment for the 1932 Buick 90 Series is available from Firestone, Lester, Excelsior, and STA. These offerings also span several tire series, including Firestone Balloon, Firestone Classic Bias Ply, Lester Classic Bias Ply, Comp H, and Transport Highway.
Those brand and series differences are most useful as a way to compare appearance, stated rim-width range, weight, and general tire character rather than to chase a simple brand hierarchy. Once the correct 700-18 size is established, the better approach is to match the tire’s style and specification to the Buick’s wheels and the kind of finished look you want.
Restoration & Appearance
Which tire should I choose for a period-style 1932 Buick 90 Series?
A period-style starting point for a 1932 Buick 90 Series is a 700-18 bias-ply tire, because that preserves the vintage construction type and overall visual character associated with the car’s era. Within that size, the choice becomes whether a blackwall, wide whitewall, or double-whitewall presentation best suits the particular restoration.
That decision depends on how the Buick is being finished rather than on size alone. A more formal, luxury-oriented build may call for a whitewall treatment, while another car may look more appropriate on blackwalls. When exact originality matters, compare the tire style against period Buick literature, marque-club guidance, or surviving reference cars.
Does correct tire fitment matter for a 1932 Buick 90 Series restoration?
Yes, correct tire fitment matters a great deal on a 1932 Buick 90 Series restoration. The proper 700-18 size affects stance, wheel proportion, and the visual balance of a large early-1930s automobile, while the bias-ply construction helps maintain the traditional profile expected on a car of this age.
Fitment also matters mechanically, because older wheels and tires should work together as a system. A tire that is correct in size but mismatched to the wheel width or intended appearance can undermine the finished result. Restorers usually get better outcomes by confirming wheel dimensions early and selecting a sidewall style that supports the overall presentation.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1932 Buick 90 Series?
Yes. A 1932 Buick 90 Series may still call for a 700-18 tire, but wheel replacements, brake conversions, suspension work, or body changes can alter what fits safely and cleanly on the car. Even when the tire size stays the same, the actual wheel dimensions may no longer match an original-style setup.
That is why the current wheel diameter and width should be checked before mounting new tires. Steering clearance, fender clearance, and the condition of springs and suspension components also deserve attention on an older collector vehicle, especially if the Buick has been restored in stages or carries modifications done many years ago.
What should I inspect before driving a 1932 Buick 90 Series on new tires?
Before driving a 1932 Buick 90 Series on new tires, inspect the wheels for damage, corrosion, and proper bead-seating surfaces, then confirm tire pressure and secure mounting. The suspension, steering linkage, and brakes also deserve a careful check, because a large prewar car places real demands on every chassis component.
A short test drive should follow before any sustained road use. Watch for rubbing, unusual vibration, pull, or signs that the tires are not centering properly on the wheels. Collector cars that sit for long periods also benefit from checking wheel bearings, fluid levels, and general mechanical readiness rather than focusing on the tires alone.
How should 700-18 tires on a collector 1932 Buick 90 Series be maintained?
700-18 tires on a collector 1932 Buick 90 Series should be maintained with regular pressure checks, routine visual inspections, and proper storage habits. Look for cracking, cuts, bulges, uneven wear, or slow air loss, especially if the Buick spends long periods parked and sees only occasional road use.
Storage conditions matter almost as much as mileage on an older collector car. Keeping the Buick away from prolonged sunlight, excess heat, moisture, and ozone sources helps protect the sidewalls and casing over time. Periodic inspection is still important even when tread looks fresh, because age and storage history affect serviceability on vintage tires.
