1940 Buick 80 Series Tires

The 1940 Buick 80 Series uses a 750-16 tire size. That is a numeric bias-ply size mounted on a 16-inch rim, and the covered 8-cylinder sub-model uses the same fitment.

For most owners, the question is not which primary size fits, but which 750-16 tire best suits the car. A wide whitewall can support a restoration-oriented appearance, while blackwall and utility-style patterns create a different look and use profile. Wheel width and the car’s actual wheel setup should still be checked before selecting a tire.

The 1940 Buick 80 Series uses a 16-inch rim with its 750-16 tire size. Several 750-16 tire options in this application are built around a 5.00 to 6.00 inch rim-width range, which is an important compatibility detail when comparing products.

Rim diameter is only part of the fitment picture on a prewar car. The wheel should also be measured for width and inspected for condition, especially if the Buick has older wheels, replacement rims, or past restoration work. Matching the tire to both wheel diameter and width helps preserve proper tire shape and avoids unnecessary fitment issues.

Yes. The 1940 Buick 80 Series 8 Cyl. uses the same 750-16 bias-ply tire size as the main vehicle application. That makes sub-model fitment relatively simple compared with vehicles that split tire sizes across trims or body configurations.

Even with shared fitment, tire selection can still vary depending on the result you want. Some 750-16 tires focus on classic passenger-car appearance with blackwall or wide whitewall styling, while others carry more utility-oriented tread and load characteristics. Checking the existing wheels and deciding how the Buick will be shown or driven will narrow the right choice.

Start with the correct 750-16 size and confirm that the tire matches the Buick’s 16-inch wheel setup. Since this application stays within bias-ply construction, the biggest differences come from sidewall style, tire series, rim-width compatibility, and whether the tire is oriented more toward classic passenger-car appearance or heavier-duty service.

A wide whitewall usually suits a more formal prewar presentation, while a blackwall changes the visual character considerably. It also helps to compare load specifications where they are listed and to think honestly about how the car will be used. A show-focused restoration and a vehicle expected to handle utility or secondary-road driving may point toward different 750-16 options.

The available 750-16 tires for a 1940 Buick 80 Series include both blackwall and wide whitewall sidewall styles. That gives owners two distinctly different visual directions while keeping the original size and bias-ply construction format intact.

Sidewall style affects the car’s overall presence almost as much as the wheel itself on a large prewar Buick. Wide whitewalls create a more formal, restoration-oriented look, while blackwalls feel plainer and sometimes more utilitarian depending on the tread series. The best choice depends on how closely the finished car should reflect period style and how the Buick will be presented.

The 750-16 fitment for the 1940 Buick 80 Series is available from Firestone, Lester, BFGoodrich, and STA. Those brands cover a mix of classic passenger-style bias-ply tires as well as heavier-duty military and transport-oriented designs in the same size.

Brand choice should be considered alongside the tire series, sidewall style, and the intended role of the car. Firestone, Lester, and BFGoodrich options support more traditional collector-car presentation, while several STA products lean toward utility or truck-style service. Comparing those characteristics is more useful than choosing by brand name alone.

A period-style 1940 Buick 80 Series usually starts with the correct 750-16 bias-ply size. Within that size, classic passenger-car tires with blackwall or wide whitewall styling align more naturally with the Buick’s prewar character than utility-oriented military or transport-type tread patterns.

The exact appearance target matters. A wide whitewall creates a more formal restoration-oriented presentation, while blackwall delivers a quieter and more restrained look. If exact originality is important, period photos, marque references, and vehicle-specific restoration documentation are the right way to confirm whether a particular sidewall treatment suits your individual Buick.

On a restored 1940 Buick 80 Series, bias-ply construction plays a major role in preserving the car’s traditional visual stance. The 750-16 fitment in this application remains bias-ply, which supports the period-style look many prewar Buick owners want from both the side profile and the shape of the tire on the wheel.

Appearance is not just about construction alone, though. Sidewall treatment and tread character also shape how authentic, formal, or utilitarian the finished car appears. A wide whitewall passenger-style tire gives a very different impression than a blackwall transport or military pattern, even when the size is the same 750-16.

Yes. Even though the primary fitment is 750-16 on a 16-inch rim, modifications can change whether a particular tire works well on the car. Replacement wheels, altered wheel width, brake updates, suspension work, ride-height changes, or body repairs can all influence clearance and tire shape.

That is especially important on an older vehicle that may have gone through several decades of maintenance or restoration. Measuring the actual wheel, checking steering travel, and looking at fender and suspension clearance before mounting tires helps prevent surprises. A Buick that appears stock from the outside may still have meaningful wheel or chassis changes underneath.

Before road use, inspect the wheels for correct diameter, width, and structural condition, then confirm that the tires seat properly and hold pressure evenly. The steering and suspension should also be checked so the new 750-16 tires have adequate clearance and are not being asked to compensate for worn chassis components.

A prewar Buick benefits from a careful walk-around before any serious drive. Look for sidewall damage, tread irregularities, valve-stem issues, and signs of rubbing after a short initial run. It also helps to verify brake function and alignment behavior, since a newly mounted tire can reveal wheel or suspension problems that were less obvious before.

Collector-car 750-16 tires should be maintained with regular pressure checks, visual inspections, and careful storage habits. A Buick that sits for long periods can still develop aging issues, so sidewall cracking, flat spotting, cuts, bulges, and slow air loss deserve attention even when tread wear remains minimal.

Storage conditions matter on seldom-driven prewar cars. Keeping the Buick away from prolonged sunlight, excess heat, moisture, and ozone sources can help preserve the tires between drives. Periodic inspection of wheel condition and a quick clearance check after any suspension or brake work are also smart steps before returning the car to regular road use.
