The 1933 Buick 60 Series came from an era when Buick balanced prestige, smooth power, and substantial road presence in the early Depression years. Cars of this period depend heavily on the right tire profile to preserve stance, steering feel, and the visual character that makes a prewar Buick look settled on its chassis. The 1933 Buick 60 Series uses a 6.50-17 bias-ply tire on a 17-inch rim. That keeps the tire decision focused less on fitment variety and more on selecting the right period-style construction for restoration goals and careful road use. For a touring car like this, condition, wheel suitability, and authentic-looking proportions all matter.
Which Tire Size Is Right for The 1933 Buick 60 Series
The 1933 Buick 60 Series uses one primary tire size: 6.50-17. This is a bias-ply fitment for a 17-inch rim, and it remains the same for the covered 8-cylinder sub-model, so the decision is less about choosing between sizes and more about selecting the right period-style tire and confirming that the wheels on the car still match the original fitment pattern.
The 6.50-17 size uses a numeric bias-ply format in which 6.50 refers to the nominal section width in inches and 17 identifies the rim diameter. On a 1933 Buick 60 Series, that sizing reflects the tall, substantial tire proportions expected on a prewar American car and works with the traditional driving character of bias-ply construction. Buyers considering this size are usually balancing appearance, intended road use, and the condition of the car's existing wheels. It is the right starting point when the goal is to keep the Buick's period-style stance and proper 17-inch fitment.
Tire fitment is straightforward for the covered 1933 Buick 60 Series sub-model. The 8-cylinder version uses the same primary size, so the key step is confirming that the car still has the correct 17-inch wheel setup before choosing a replacement tire.

Frequently Asked Questions
Owners of a 1933 Buick 60 Series usually need clear guidance on 6.50-17 sizing, 17-inch rim fitment, period-style bias-ply construction, restoration appearance, and the checks that matter before putting a prewar Buick back on the road.
Tire Size & Fitment
What tire size fits a 1933 Buick 60 Series?
The 1933 Buick 60 Series uses a 6.50-17 tire size. This is a numeric bias-ply fitment, and it is the primary size associated with the model covered here, including the 1933 Buick 60 Series 8 Cyl.
That means the first thing to confirm is that the car still has 17-inch wheels intended for this traditional prewar size. Many older cars have seen wheel changes over the decades, so matching the tire to the actual wheel diameter and overall setup matters just as much as ordering the correct size code.
What size rim does a 1933 Buick 60 Series use?
The 1933 Buick 60 Series uses a 17-inch rim with its 6.50-17 tire fitment. The tire size itself reflects that wheel diameter, with the final number in the size code indicating the 17-inch rim.
Wheel diameter should be verified on the car before mounting replacement tires, especially on a prewar vehicle that may have had parts exchanged during restoration or long-term ownership. A correct-looking tire can still be the wrong choice if the wheel diameter or wheel condition no longer matches the intended 17-inch setup.
Does the 1933 Buick 60 Series 8 Cyl. use the same tire size?
Yes. The 1933 Buick 60 Series 8 Cyl. uses the same 6.50-17 bias-ply tire size as the covered 1933 Buick 60 Series fitment. There is no separate primary size change within the sub-model information here.
That makes tire selection simpler, but it still helps to inspect the actual wheels on the vehicle before making a final choice. On an older Buick, past repairs, replacement wheels, or long-stored components can affect what the car will safely accept even when the original tire size remains consistent.
Choosing the Right Tire
What should I consider when choosing a 6.50-17 tire for a 1933 Buick 60 Series?
Start with the correct primary size and construction. A 1933 Buick 60 Series uses a 6.50-17 bias-ply tire, so the main considerations are keeping the proper prewar sizing format, confirming the 17-inch wheel setup, and choosing a tire that suits the car's restoration goals and intended driving use.
A Buick from this era benefits from tire proportions that preserve its tall stance and traditional appearance. Wheel condition, storage history, and how the car is actually driven should all factor into the decision, since a show-focused restoration and a road-driven collector car may place different priorities on tire presentation and service readiness.
How do I choose between the available 6.50-17 tires for a 1933 Buick 60 Series?
The best way to compare 6.50-17 options for a 1933 Buick 60 Series is to stay with the correct size first, then evaluate the tire's overall presentation and how closely it matches the character of the car. For a prewar Buick, appearance and proportion are often just as important as basic fitment.
A restoration-oriented owner may prioritize a traditional look that complements the Buick's body lines and wheel design, while a driver-focused owner may place more emphasis on service condition and confidence for occasional road miles. Matching the tire choice to the vehicle's purpose usually leads to a more satisfying result than focusing on size code alone.
What rim-fitment details matter when choosing 1933 Buick 60 Series tires?
The critical rim-fitment detail is the 17-inch wheel diameter required by the 6.50-17 tire size. On a 1933 Buick 60 Series, that basic match between tire and wheel is the foundation for proper mounting and for preserving the intended prewar tire profile.
Condition matters almost as much as size on an older car. Wheels should be inspected for damage, corrosion, previous repairs, and general suitability before new tires go on, especially if the Buick has been stored for years or restored in stages. A sound wheel setup helps the correct tire size perform as intended on the road.
Restoration & Appearance
Which tire should I choose for a period-style 1933 Buick 60 Series?
For a period-style 1933 Buick 60 Series, the right starting point is the original fitment format: a 6.50-17 bias-ply tire on a 17-inch rim. That preserves the tall sidewall proportions and traditional construction style that suit a substantial prewar Buick.
Appearance-focused buyers should look at how the tire complements the car's overall stance, wheel presentation, and restoration theme rather than treating any one tire as automatically authentic in every detail. When exact originality matters, comparing the finished look against marque references and restoration photography is a sensible next step.
Does correct tire fitment matter for a 1933 Buick 60 Series restoration?
Yes, correct tire fitment plays a major role in how a 1933 Buick 60 Series looks and sits. The 6.50-17 size and bias-ply construction contribute to the vehicle's visual balance, and changing away from that format can alter both stance and period character.
Restoration decisions are not just cosmetic. Tire size also affects wheel compatibility and how naturally the car fills its fender openings, so it is worth confirming the actual wheels on the Buick before finalizing a replacement. On prewar cars, the right proportions often make as much difference as the finish details elsewhere.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1933 Buick 60 Series?
Yes. Modifications can change what works on a 1933 Buick 60 Series even when 6.50-17 is the original primary tire size. Replacement wheels, altered suspension height, brake conversions, or body and fender changes can all affect the space and wheel setup available for a new tire.
A careful check of actual wheel diameter, wheel width, and clearance around suspension and sheet metal is worthwhile before mounting tires on any modified prewar car. Even small departures from the original setup can change how the tire sits, so the vehicle should be evaluated as it exists now rather than as it left the factory.
What should I inspect before driving a 1933 Buick 60 Series on new tires?
Before driving a 1933 Buick 60 Series on new tires, inspect the wheels, lug hardware, valve components, and the general condition of the suspension and steering. A prewar car should also be checked for any signs of interference at full steering lock or under normal suspension movement.
Road readiness depends on more than fresh rubber. Tire pressure should be set appropriately, and the car should be looked over for worn components that could affect tracking or stability. A short, careful test drive is a smart way to confirm that the Buick behaves properly before moving on to longer trips.
How should 6.50-17 tires on a collector 1933 Buick 60 Series be maintained?
Collector-car tires in 6.50-17 should be maintained with regular pressure checks, visual inspections, and sensible storage habits. On a 1933 Buick 60 Series that sees limited use, sidewall condition, tread condition, and signs of air loss deserve attention even when the car is driven only occasionally.
Long periods of inactivity can be hard on older vehicles, so the Buick should be kept away from prolonged sunlight, excess heat, and moisture when possible. It also helps to inspect the tires before each outing rather than assuming low mileage means low risk, since age and storage can matter as much as tread wear.
