The 1933 Chrysler CQ comes from an era when American cars were balancing streamlined styling, improved road manners, and everyday durability during the early Depression years. For owners preserving one of these pre-war Chryslers, tire choice affects far more than appearance alone, because the car was built around a 6.50-17 bias-ply tire on a 17-inch rim. That keeps the fitment decision focused on maintaining the proper vintage construction and proportions rather than sorting through multiple primary sizes. A period-style replacement in the correct numeric bias-ply format helps preserve the car’s stance and character, while careful attention to wheel condition, age, and overall tire health remains essential before regular road use.
Which Tire Size Is Right for The 1933 Chrysler CQ
The 1933 Chrysler CQ uses one primary tire size: 6.50-17. It is a bias-ply fitment mounted on a 17-inch rim, and the covered CQ sub-model uses that same size. That means the main decision is not choosing between multiple fitments, but selecting the right 6.50-17 tire for the car’s intended use, vintage appearance, and overall wheel condition.
A 6.50-17 tire uses the vintage numeric bias-ply sizing system, where 6.50 refers to the nominal section width in inches and 17 identifies the wheel diameter. On a 1933 Chrysler CQ, this format matches the period construction the car was designed to use, so the tire’s shape, stance, and road feel remain closely tied to the original style of fitment. Because the CQ stays with one primary size, selection centers on finding a sound 6.50-17 bias-ply tire and confirming that the wheels, rims, and overall chassis setup are still appropriate for that specification before putting the car back into service.
Tire fitment is straightforward across the covered 1933 Chrysler CQ lineup. The listed sub-model uses the same 6.50-17 bias-ply size, so the focus stays on correct vintage sizing, wheel condition, and choosing a tire that suits the car’s restoration direction and road use.

Frequently Asked Questions
Owners researching 1933 Chrysler CQ tires usually need clear guidance on 6.50-17 sizing, 17-inch rim fitment, period-style bias-ply selection, and the inspections that matter before a pre-war car returns to the road.
Tire Size & Fitment
What tire size fits a 1933 Chrysler CQ?
The 1933 Chrysler CQ uses a 6.50-17 tire. That is the primary fitment for this model, and it is a bias-ply size built around a 17-inch rim, which reflects the vintage construction and dimensions the car was designed to use.
Choosing the correct size is only the first step on a pre-war vehicle. The next things to verify are that the wheels on the car are still the proper 17-inch diameter, that they are in sound condition, and that no earlier owner changed the wheel or suspension setup in a way that affects clearance or overall fitment.
What size rim does a 1933 Chrysler CQ use?
A 1933 Chrysler CQ uses a 17-inch rim with its 6.50-17 tire size. In this older numeric bias-ply format, the final number identifies the wheel diameter, so the 17 in 6.50-17 corresponds to the rim diameter rather than the tire’s overall height.
Rim diameter should be confirmed before any tire purchase, especially on a collector car that may have seen parts changes over many decades. Checking the wheel itself also helps catch issues such as bent rims, corrosion, or mismatched wheels that could complicate mounting and change how the car sits or drives.
Does the 1933 Chrysler CQ Base use the same tire size?
Yes. The 1933 Chrysler CQ Base uses the same 6.50-17 bias-ply tire size as the core 1933 Chrysler CQ fitment. There is no alternate primary size shown for that sub-model, so the fitment path stays simple at the sub-model level.
That consistency means the real decision is not between different factory size groupings, but between individual 6.50-17 tire choices and the condition of the wheels they will mount on. It is still worth confirming that the car has not been modified with different rims, replacement axles, or altered suspension parts that could affect actual clearance.
Choosing the Right Tire
What should I consider when choosing a 6.50-17 tire for a 1933 Chrysler CQ?
Start with the correct primary size and construction. A 1933 Chrysler CQ uses a 6.50-17 bias-ply tire, so the most important factors are staying with that vintage format, confirming the 17-inch wheel diameter, and choosing a tire that suits the car’s intended use, whether that is show presentation, occasional touring, or general collector driving.
Pre-war cars respond noticeably to changes in tire dimensions and wheel condition, so selection should also include a close look at rim integrity, bead-seat condition, and overall chassis setup. A period-style tire may better preserve the Chrysler’s traditional stance, while an owner focused on road use should also inspect steering, suspension, and alignment before judging the tire itself.
How do I choose between available 6.50-17 tires for a 1933 Chrysler CQ?
The best way to compare 6.50-17 tires for a 1933 Chrysler CQ is to keep the fitment fixed and then evaluate the details that matter to your goals. Since the car uses one primary size, the comparison shifts to construction authenticity, visual presentation, and whether the tire suits a restoration-oriented car or one that will see more regular road miles.
A useful approach is to begin with the car’s purpose rather than shopping by appearance alone. A Chrysler intended for judged events may call for a more traditional tire presentation, while a driver-quality car still needs the same careful attention to wheel condition, tire age, and overall compatibility before it is trusted for longer runs.
What rim-fitment details matter when choosing 1933 Chrysler CQ tires?
For a 1933 Chrysler CQ, the essential rim-fitment detail is matching the 6.50-17 tire to a proper 17-inch wheel in good condition. On older vehicles, the wheel itself matters as much as the size because decades of use, storage, repairs, or parts swapping can change the actual mounting situation.
Close inspection should include checking for cracks, heavy rust, flange damage, and signs that the wheels are not a matched set. A tire can be the correct size on paper and still create problems if the rim has been distorted or replaced with something non-original, so wheel condition and wheel identity deserve attention before the tire choice is finalized.
Restoration & Appearance
Which tire should I choose for a period-style 1933 Chrysler CQ?
A period-style 1933 Chrysler CQ should begin with the correct 6.50-17 bias-ply size. That keeps the car in the vintage numeric format and construction type associated with its era, which helps preserve the visual balance, stance, and overall character expected of an early 1930s Chrysler.
When appearance matters, staying with the proper size and traditional construction is usually more important than chasing modern substitutions. Owners seeking exact historical authenticity should compare any final tire choice against marque references, restoration photos, and other vehicle-specific historical sources, since period-style and exact originality are not always the same thing.
Does correct tire fitment matter for a 1933 Chrysler CQ restoration?
Yes, correct tire fitment matters a great deal on a 1933 Chrysler CQ restoration. The car’s proportions, fender relationship, ride height, and overall visual impression are closely tied to the 6.50-17 bias-ply specification, so an incorrect size can change the restored car’s look even before it affects road behavior.
Fitment also matters mechanically, because an older chassis depends on proper wheel and tire dimensions for predictable clearance and steering travel. Even on a display-focused restoration, the wheels should be inspected carefully and the tires should be chosen with the car’s actual use in mind rather than treating size as a cosmetic detail alone.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1933 Chrysler CQ?
Yes. Modifications can affect tire fitment on a 1933 Chrysler CQ even when the intended tire size remains 6.50-17. Changes such as replacement wheels, altered suspension height, brake conversions, or body repairs can influence steering clearance, fender clearance, and how the tire sits on the car.
That is why an older vehicle should be inspected as it exists today rather than assumed to be unchanged. A CQ that has aftermarket wheels or non-original suspension parts may need closer measurement and a more careful wheel check before mounting new tires, especially if the car has been rebuilt over many decades.
What should I inspect before driving a 1933 Chrysler CQ on new tires?
Before driving a 1933 Chrysler CQ on new tires, inspect the wheels, valve hardware, and the overall condition of the steering and suspension. New rubber cannot compensate for loose front-end components, cracked wheels, poor alignment, or brake issues that often appear on long-stored collector cars.
A careful pre-drive check should also include tire pressure, lug security, signs of rubbing at full steering lock, and any evidence of fluid leaks that could affect braking or handling. A short local test drive is a smart first step, since it gives the owner a chance to verify tracking, clearance, and general road manners before longer use.
How should 6.50-17 tires on a collector 1933 Chrysler CQ be maintained?
6.50-17 tires on a collector 1933 Chrysler CQ should be maintained with regular pressure checks, visual inspections, and careful storage habits. Because cars of this era are often driven infrequently, tire aging can become as important as tread wear, particularly when a vehicle spends long periods parked indoors or in seasonal storage.
Good maintenance also means watching for sidewall cracking, bulges, cuts, flat spotting, and slow air loss before each outing. Keeping the car away from prolonged sunlight, moisture, and ozone sources helps protect the tires, and occasional inspection of wheel condition is just as important since the rim can be a limiting factor on an older Chrysler.
