1931 Oakland V8 Tires

The 1931 Oakland V8 uses a 550-18 tire size. This is a numeric bias-ply fitment for an 18-inch rim, and it is the primary size associated with the model covered here, including the Base sub-model.

That means the first step is confirming that the car still has the proper 18-inch wheels and has not been changed to a different wheel setup over the years. Once the size is confirmed, the choice usually comes down to sidewall style, tire series, and whether the goal is a more understated driver presentation or a more restoration-oriented pre-war look.

The 1931 Oakland V8 uses an 18-inch rim with its 550-18 tire size. Product offerings in this size show rim-width specifications that vary by tire, including examples around 3 inches, 3.25 inches, 4 inches, and a wider stated range on some applications.

Rim diameter is the non-negotiable starting point, but rim width still matters when comparing actual tires in the same size. A car that has had replacement wheels fitted decades ago may still have the right diameter but a different width, so it is worth measuring the wheel before choosing among available 550-18 tires.

Yes. The 1931 Oakland V8 Base uses the same 550-18 bias-ply tire size as the model coverage shown here. There is no separate primary tire size for the Base within this fitment grouping.

That makes selection more straightforward, because you do not need to sort between multiple primary sizes by trim. The practical checks shift to wheel condition, wheel width, and the type of appearance you want, since 550-18 is available in several period-style presentations including blackwall, wide whitewall, and double-whitewall.

Start with the correct 550-18 size and confirm that the car still uses the proper 18-inch wheels. From there, compare the available bias-ply options by brand, tire series, sidewall treatment, and the rim-width specification attached to each tire.

A blackwall usually gives a more restrained touring appearance, while wide whitewall and double-whitewall options create a stronger restoration-era visual statement. It also helps to think about how the car will be used, since a lightly driven show car and a regularly exercised collector car may lead you toward different priorities within the same size.

The 1931 Oakland V8’s 550-18 tire size is available with several sidewall treatments, including blackwall, wide whitewall, and double-whitewall styles. Those options give the car a noticeably different visual character even when the underlying size and bias-ply construction stay the same.

Choosing the sidewall style depends on the look you want the car to carry. A blackwall tends to feel more understated and functional, while whitewall and double-whitewall presentations can emphasize the formal, upscale styling often associated with early-thirties automobiles. The best choice is the one that suits the car’s finish, trim, and restoration direction.

The 550-18 size for a 1931 Oakland V8 is available from Excelsior, Firestone, BFGoodrich, and Michelin. Those brands appear across several period-style tire series, including Comp H, Firestone Classic Bias Ply, Silvertown Classic Bias Ply, and Double Rivet.

Brand alone is only part of the decision. It is just as important to compare the sidewall style you want and the wheel dimensions the tire is intended to work with, especially on a pre-war vehicle that may have seen wheel changes or restoration work over time. The better comparison is brand plus series, sidewall, and wheel compatibility together.

A period-style 1931 Oakland V8 starts with the correct 550-18 bias-ply size, since that preserves the car’s original-era tire format and visual proportions. Within that size, choices such as Firestone Classic Bias Ply, Silvertown Classic Bias Ply, Comp H, and Double Rivet create different traditional presentations without departing from the proper construction type.

The most suitable choice depends on how closely the car is being restored and how much emphasis is placed on visual detail. Buyers aiming for exact historical accuracy should compare the tire’s sidewall treatment and overall presentation with marque references, period photography, and restoration documentation rather than assuming any single brand or whitewall style is automatically authentic.

On a restored 1931 Oakland V8, bias-ply construction plays a major role in preserving the car’s proper pre-war look. The 550-18 fitment carries the narrower, taller period-style appearance that suits the body, fender openings, and wheel design of an early-thirties automobile.

Appearance is also shaped by the sidewall you choose, since blackwall, wide whitewall, and double-whitewall options can shift the car’s visual tone significantly. Even when the tire size is correct, a different sidewall treatment can make the vehicle look more formal, more sporting, or more restrained, so the visual outcome deserves as much attention as the fitment itself.

Yes. A 1931 Oakland V8 may still call for a 550-18 tire, but fitment can change if the car has replacement wheels, altered suspension height, brake conversions, or body and fender work that differs from stock dimensions. Even older collector cars can pick up these changes over decades of ownership.

The practical approach is to verify the actual wheel diameter and width on the car before selecting a tire, then check steering and fender clearance with the suspension at normal ride height. Pre-war cars deserve extra attention here because an old modification can be easy to miss until the new tires are mounted.

Before road use, inspect the wheels for damage, rust, cracks, and bead-seat condition, then confirm that the tires are mounted in the correct 550-18 size for the car. It is also wise to check valve stems, inflation pressure, and basic clearance at the front wheels through the full steering range.

A 1931 Oakland V8 is old enough that the rest of the chassis matters just as much as the new tires. Look over suspension wear, wheel bearings, brake function, and any signs of rubbing once the car is on the ground. A short, careful shakedown drive can reveal issues before the vehicle is asked to handle a longer outing.

Maintain 550-18 tires on a collector 1931 Oakland V8 by keeping them properly inflated, inspecting the sidewalls and tread regularly, and watching for cuts, bulges, cracking, or unexplained air loss. Collector vehicles that sit for long periods deserve closer attention because tire aging can occur even when mileage stays low.

Storage conditions matter on a pre-war car. Keeping the Oakland in a cool, dry space away from prolonged sunlight and ozone sources can help preserve the tires’ condition over time. It also helps to move the car periodically or avoid leaving it parked in one position for extended stretches, especially during off-season storage.
