The 1933 Buick 90 Series came from an era when Buick’s large straight-eight luxury cars balanced prestige, presence, and long-distance touring ability. As one of Buick’s senior models of the early 1930s, it carries the kind of substantial chassis and formal styling that make tire choice especially important to both stance and driving character. The 1933 Buick 90 Series uses a 700-17 bias-ply tire on a 17-inch rim. Available choices include traditional blackwall, wide whitewall, and double-whitewall presentations in period-style tire series. For a restoration-minded owner, the main decision is usually how closely the tire’s construction and sidewall look should match the car’s intended appearance and use.
Which Tire Size Is Right for The 1933 Buick 90 Series
The 1933 Buick 90 Series uses one primary tire size: 700-17. That fitment is a bias-ply tire for a 17-inch rim, and it remains consistent for the covered 8-cylinder sub-model. Once size is settled, the real choice becomes sidewall style, tire series, and whether the tire’s overall look suits a touring presentation, a darker original-style appearance, or a restoration with more visual contrast.
In a numeric bias-ply size like 700-17, the 700 indicates an approximate 7.00-inch nominal section width and the 17 identifies the wheel diameter in inches. This is a traditional bias-ply construction, which matches the period driving feel and visual character expected on a full-size 1933 Buick 90 Series. Within this size, there are choices from Firestone and Ensign, along with blackwall, wide whitewall, and double-whitewall sidewall treatments in series such as Firestone Balloon and Ensign B5. Choosing among them usually comes down to restoration style, wheel compatibility, and the kind of road use planned for the car.
Fitment is straightforward on the covered 1933 Buick 90 Series sub-model. The tire size remains consistent, so checking the sub-model mainly helps confirm that the car still retains the expected wheel and tire setup before comparing product styles.

Tire Size & Fitment
What tire size fits a 1933 Buick 90 Series?
The 1933 Buick 90 Series uses a 700-17 tire size. This is a numeric bias-ply fitment, and it pairs with a 17-inch rim. The covered 8-cylinder sub-model uses the same primary size, so the fitment question is generally straightforward.
Once the 700-17 size is confirmed, the next step is comparing the tire’s sidewall style and product specifications rather than looking for a different primary size. It is also wise to verify that the car still has the expected wheel diameter and width, especially if it has been restored, stored for years, or altered at some point in its life.
What size rim does a 1933 Buick 90 Series use?
The 1933 Buick 90 Series uses a 17-inch rim with its 700-17 tire fitment. Product offerings in this size show rim-width specifications that include 4 inches, with some options covering a 3.5- to 4.0-inch range. That makes wheel confirmation an important part of tire selection.
Rim diameter should match the tire size exactly, but width also matters when comparing specific 700-17 products. On a collector car, it is smart to inspect each wheel individually for width, condition, and any signs of prior replacement, since mixed wheels or later substitutions can complicate what looks like a simple one-size fitment.
Does the 1933 Buick 90 Series 8 Cyl. use the same tire size?
Yes. The 1933 Buick 90 Series 8 Cyl. uses the same 700-17 bias-ply tire size as the model core. There is no alternate primary size shown for that covered sub-model, so the fitment itself remains consistent across the page’s Buick 90 Series coverage.
That consistency means the buying decision centers more on tire style than on sub-model differences. The owner can focus on blackwall versus whitewall appearance, the tire series being considered, and whether the current wheels still match the required 17-inch setup rather than sorting through multiple primary size options.
Choosing the Right Tire
What should I consider when choosing a 700-17 tire for a 1933 Buick 90 Series?
Start with the correct 700-17 size and 17-inch rim requirement, then compare the construction and product details within that size. The available choices are bias-ply tires, so the decision is mostly about matching the car’s intended look and use rather than choosing between different primary fitments.
Sidewall style is one of the biggest visual differences, with blackwall, wide whitewall, and double-whitewall options available. It also helps to compare rim-width specifications and load figures for the exact tire being considered, especially on a large prewar Buick where wheel setup, vehicle weight, and restoration goals all influence the right choice.
What sidewall styles are available for 1933 Buick 90 Series tires?
The 1933 Buick 90 Series has 700-17 tire options in blackwall, wide whitewall, and double-whitewall styles. All of them stay within the same primary size, but they change the car’s presentation noticeably. That makes sidewall choice one of the most important appearance decisions on this fitment.
A blackwall tire gives the Buick a more restrained and utilitarian look, while whitewall and double-whitewall styles add more visual contrast around the wheel. Since sidewall treatment does not change the basic fitment, the practical step is to choose the look that best matches the car’s restoration direction and then confirm wheel compatibility for the exact tire selected.
What brands offer tires for the 1933 Buick 90 Series?
Tires for the 1933 Buick 90 Series in 700-17 are available from Firestone and Ensign. The Firestone offerings appear in the Firestone Balloon series, while Ensign appears in the Ensign B5 series. Both brands stay within the correct bias-ply construction for this fitment.
Brand choice should be considered alongside sidewall style, rim-width specification, and the overall look you want on the car. Rather than treating the decision as a brand contest, it is more useful to compare which tire has the appearance and wheel compatibility that best suits a touring Buick from the early 1930s.
Restoration & Appearance
Which tire should I choose for a period-style 1933 Buick 90 Series?
A period-style 1933 Buick 90 Series starts with the correct 700-17 bias-ply size on a 17-inch rim. Within that fitment, choices such as Firestone Balloon and Ensign B5 keep the construction and general visual character in line with what buyers expect on a substantial prewar Buick.
The next decision is how formal or understated the car should look once the wheels are mounted. Blackwall, wide whitewall, and double-whitewall options create very different presentations, so owners pursuing exact historical authenticity should compare the tire choice against period photos, marque references, or restoration records for their specific car.
How does tire construction affect the appearance of a restored 1933 Buick 90 Series?
On a restored 1933 Buick 90 Series, bias-ply construction plays a major role in the car’s finished look. The 700-17 fitment available here is bias-ply, which preserves the tall, upright, prewar visual character associated with large American cars of the early 1930s.
Appearance is influenced not just by the size, but also by the sidewall treatment and tire series selected within that size. A blackwall can make the car look more reserved, while whitewall variations add more visual prominence at the wheel openings, so construction and sidewall style should be considered together rather than as separate choices.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1933 Buick 90 Series?
Yes. Even though the primary fitment is 700-17, modifications can affect how that tire works on a 1933 Buick 90 Series. Changes to wheel width, replacement rims, suspension height, brake conversions, or body clearance can all alter the fitment picture on a car of this age.
A Buick that still appears stock can also carry older repairs or replacement parts that are not obvious at first glance. Checking wheel diameter, wheel width, steering clearance, and space at the fenders before mounting tires helps avoid problems, particularly when the car has an incomplete history or has been through earlier restoration work.
What should I inspect before driving a 1933 Buick 90 Series on new tires?
Before driving a 1933 Buick 90 Series on new tires, inspect the wheels for damage, rust, cracks, and proper size, then confirm the tires are mounted and inflated appropriately for the chosen product. It is also smart to check lug hardware, valve stems, and basic chassis condition before road use.
A large prewar car places real demands on tires, so the inspection should continue beyond the tires themselves. Steering response, brake function, suspension movement, and tire-to-body clearance are all worth checking during a careful initial drive, especially if the Buick has been stored for a long period or has not been driven recently.
How should 700-17 tires on a collector 1933 Buick 90 Series be maintained?
700-17 tires on a collector 1933 Buick 90 Series should be inspected regularly for pressure loss, sidewall cracking, cuts, bulges, and uneven tread wear. Collector vehicles often spend long periods parked, so condition checks matter just as much as mileage on a tire that sees only occasional road use.
Storage conditions also play a big part in tire life. Keeping the Buick away from prolonged sunlight, excess heat, moisture, and ozone sources helps protect the rubber, while periodic movement can reduce flat-spotting during long storage. A visual inspection before each outing is a sensible habit on any prewar touring car.
