The 1933 Nash 1180 comes from a period when American cars were expected to deliver substantial road presence, mechanical durability, and a composed ride on the tire technology of the day. For owners restoring or maintaining one now, the tire decision is closely tied to preserving that prewar character while keeping the car usable and properly proportioned. The 1933 Nash 1180 uses a 6.50-17 bias-ply tire on a 17-inch rim. That keeps the focus on choosing the right period-style tire within the correct size rather than sorting through multiple fitments. For road use, appearance, and restoration goals alike, wheel condition, tire age, and overall vehicle setup still deserve a careful look before installation.
Which Tire Size Is Right for The 1933 Nash 1180
The 1933 Nash 1180 uses one primary tire size: 6.50-17 in bias-ply construction on a 17-inch rim. That same fitment carries across the covered 1933 Nash 1180 Base configuration, so the main decision is not which size fits, but which period-style tire best matches the car's appearance, intended road use, and restoration direction.
The 6.50-17 size uses a vintage numeric bias-ply format in which 6.50 refers to the nominal section width in inches and 17 identifies the rim diameter. Bias-ply construction suits the prewar character of a 1933 Nash 1180 and preserves the traditional tire profile expected on a car of this era. In practical terms, the choice within this size centers on period-style presentation and making sure the tire matches the wheel and overall vehicle setup. That makes 6.50-17 the starting point for anyone aiming to keep the car visually and mechanically in step with its original design period.
Sub-model fitment for the 1933 Nash 1180 is straightforward in the covered range. The key point is that the Base model uses the same primary tire size, so selection centers on the right bias-ply tire rather than sorting through different fitments.

The tire sizes listed on this page assume factory-standard vehicle configuration. The following modifications may affect tire fitment and are not reflected in this guide:
Suspension changes (lowering, lift kits, spring replacements)
Body alterations (fender modifications, custom bodywork)
If your vehicle has been modified from factory specifications, verify tire clearance before purchase.
Frequently Asked Questions
Owners of a 1933 Nash 1180 usually need clear guidance on the 6.50-17 fitment, 17-inch rim compatibility, period-style tire selection, and the inspection steps that matter before putting a prewar car back on the road.
Tire Size & Fitment
What tire size fits a 1933 Nash 1180?
The 1933 Nash 1180 uses a 6.50-17 tire in bias-ply construction. That is the primary fitment for this model, and it is the size to match before comparing any tire choices for appearance, brand, or restoration goals.
The practical step is confirming that the car still has 17-inch wheels and has not been altered with different rims over the years. On a prewar vehicle, it also helps to inspect wheel condition, check for past modifications, and make sure the tire size on the car now has not been changed from the original fitment approach.
What size rim does a 1933 Nash 1180 use?
The 1933 Nash 1180 uses a 17-inch rim with its 6.50-17 tire size. In this sizing format, the final number identifies the wheel diameter, so matching the tire to a 17-inch rim is essential before any other selection decisions are made.
Rim diameter should be checked directly on the wheel if there is any doubt, especially on an older collector car that may have changed hands many times. A tire can look generally similar in profile yet still be wrong for the wheel, so confirming the actual rim size avoids costly mistakes and helps maintain proper fitment.
Does the 1933 Nash 1180 Base use the same tire size?
Yes. The 1933 Nash 1180 Base uses the same 6.50-17 bias-ply tire size as the core 1933 Nash 1180 fitment. That means the main question is not sub-model variation, but choosing the right tire within the proper vintage size and construction.
Even with shared fitment, it is still worth checking the actual wheel setup on the individual car before replacing tires. Older restorations, long-term storage, or prior mechanical work can leave a vehicle with mixed wheels, worn rims, or other changes that affect tire selection more than the sub-model name itself.
Choosing the Right Tire
What should I consider when choosing a 6.50-17 tire for a 1933 Nash 1180?
Start with the correct size and construction: 6.50-17 in bias-ply form. On a 1933 Nash 1180, that keeps the tire in the same vintage sizing system and preserves the traditional look and fitment relationship expected for a prewar passenger car.
After size is settled, focus on how the tire suits the vehicle's purpose. A restoration-oriented car may call for a more traditional visual presentation, while a driver should also prompt close attention to wheel condition, tire age, and overall chassis health so the new tires are working with a sound foundation.
How do I choose between the available 6.50-17 tires for a 1933 Nash 1180?
With a single primary size, the real comparison comes down to period-style appearance, construction consistency, and how closely the tire matches the role of the car. The 1933 Nash 1180 does not require sorting through multiple primary sizes, so selection can stay focused and deliberate.
A touring car used mainly for display may prioritize traditional presentation, while a car that sees more road miles still benefits from that same size being matched to sound wheels and careful installation. Looking at the whole vehicle setup usually matters more here than chasing variety for its own sake.
Why is the 6.50-17 size important on a 1933 Nash 1180?
The 6.50-17 size is important because it establishes the wheel diameter and the vintage tire profile intended for the 1933 Nash 1180. Staying with the correct primary size helps preserve the car's proportions and keeps the fitment grounded in the tire system used during its era.
Moving away from the correct size can affect how the car sits, how the wheel openings are filled, and how the tire relates to the rim. On a prewar vehicle, those visual and mechanical details matter, so the size should be confirmed first before judging any other replacement choice.
Restoration & Appearance
Which tire should I choose for a period-style 1933 Nash 1180?
A period-style 1933 Nash 1180 should begin with the correct 6.50-17 bias-ply fitment. That size and construction keep the car aligned with the tire type associated with its early 1930s design, which is an important starting point for both appearance and restoration-minded selection.
If the goal is a historically faithful presentation, the tire should complement the car's stance and prewar character rather than simply matching a wheel diameter. Owners pursuing exact originality may also want to compare the finished look against marque references, restoration photos, or other period-specific guidance before making a final choice.
Does correct tire fitment matter for a 1933 Nash 1180 restoration?
Yes, correct tire fitment matters a great deal on a 1933 Nash 1180 restoration. The proper 6.50-17 bias-ply size affects not only road use, but also the visual balance of the car, the relationship between tire and fender opening, and the overall authenticity of the finished presentation.
Prewar cars are especially sensitive to tire proportions because the tires are such a visible part of the vehicle's stance. Even when a car is not being restored for formal judging, using the right size framework helps avoid a finished look that feels too modern, too small, or simply out of character.
Fitment, Maintenance & Road Use
Can modifications affect tire fitment on a 1933 Nash 1180?
Yes. Modifications can affect tire fitment on a 1933 Nash 1180 even when the intended tire size remains 6.50-17. Wheel changes, suspension work, brake conversions, or body alterations can all change how a tire sits in the wheel opening and how it behaves at steering lock.
A car that has been restored or updated over many decades should be checked as an individual vehicle. Verifying wheel diameter, inspecting rim width, and looking for clearance issues around fenders, steering components, and suspension parts helps prevent assuming that an older modification still works with the tire you plan to install.
What should I inspect before driving a 1933 Nash 1180 on new tires?
Before road use, inspect the wheels for cracks, rust, bent areas, and any signs of previous repairs. The 1933 Nash 1180 should also have its suspension, steering components, and brake system checked so the new 6.50-17 tires are not being asked to compensate for mechanical problems elsewhere.
Tire pressure, valve condition, and proper mounting also deserve attention before the first drive. A short, cautious shakedown run is usually wise on a prewar car, since it gives the owner a chance to confirm tracking, steering response, and clearance without putting immediate long-distance demands on an unfamiliar setup.
How should 6.50-17 tires on a collector 1933 Nash 1180 be maintained?
Collector-car tires should be inspected regularly, even if the 1933 Nash 1180 is driven only occasionally. Check the 6.50-17 tires for cracking, flat spotting, cuts, bulges, irregular wear, and slow air loss, since age and storage conditions can matter as much as mileage on an older vehicle.
Storage habits make a real difference with prewar cars. Keeping the Nash away from prolonged sunlight, excess heat, moisture, and ozone sources helps protect the tires, and maintaining proper inflation reduces stress on the casing while the car sits. Any sign of deterioration should be taken seriously before the next road outing.
