1933 Nash Ambassador Tires

The 1933 Nash Ambassador uses a 700-18 tire size. That is a numeric bias-ply fitment built for an 18-inch rim, and the covered 8-cylinder sub-model uses the same primary size rather than a different alternate fitment.

That makes the size decision fairly simple, but the selection process still matters. A buyer should confirm the car still has the correct wheel diameter and a suitable wheel width for the specific 700-18 tire being considered, especially if the car has been restored, modified, or fitted with replacement wheels at some point in its life.

The 1933 Nash Ambassador uses an 18-inch rim with its 700-18 tire fitment. The rim diameter is part of the tire size itself, and the available 700-18 products are built around that same 18-inch wheel diameter.

Rim diameter should be confirmed before ordering because a vintage car may no longer have its original wheels. Width matters too, since some 700-18 tires are intended for narrower passenger-car rims while others are built around wider applications, so checking the actual wheel before choosing among available products helps avoid unnecessary fitment issues.

Yes. The covered 1933 Nash Ambassador 8 Cyl. uses the same 700-18 bias-ply tire size as the model core. There is no separate primary size shown for that sub-model within this fitment range.

That means the sub-model question is less about size differences and more about choosing the right version of 700-18. Sidewall style, tire series, rim-width suitability, and how the car is being used all become more important once the size itself is confirmed, particularly on a collector vehicle where appearance can matter as much as road manners.

Start with the confirmed 700-18 size and 18-inch rim, then compare the specific tire's construction type, rim-width suitability, sidewall style, and overall character. On this application, available choices range from traditional blackwall passenger-car styles to whitewall variants and heavier-duty alternatives within the same nominal size.

A restoration-focused car may call for a more period-style visual presentation, while a touring car may lead the owner to compare load figures and wheel-width compatibility more closely. It also helps to look at the car's actual stance and intended use, since two tires with the same size code can still serve very different presentation and driving goals.

The 1933 Nash Ambassador's 700-18 tire choices include blackwall, wide whitewall, and double-whitewall sidewall styles. Those options let the owner keep a more understated appearance or move toward a more formal pre-war presentation without changing the primary tire size.

Sidewall style affects the look of the car immediately, especially on a large 18-inch wheel where the tire is highly visible. Buyers focused on restoration appearance should compare the tire's visual treatment against the car's finish, trim, and intended era presentation, while still making sure the selected tire matches the wheel and use requirements of the vehicle.

The 1933 Nash Ambassador's 700-18 size is available from Firestone, Lester, Excelsior, and STA. Those brands cover a range of vintage tire styles, including Firestone Balloon, Firestone Classic Bias Ply, Lester Classic Bias Ply, Comp H, and Transport Highway series.

Brand choice should be considered alongside the actual tire's intended role rather than treated as the only decision point. A buyer comparing these options should look at sidewall presentation, wheel-width suitability, load figures where stated, and whether the tire is meant for a traditional passenger-car appearance or a more specialized heavy-duty application within the same size code.

A period-style 1933 Nash Ambassador should begin with the correct 700-18 bias-ply fitment, since that preserves the car's vintage tire profile and overall visual character. From there, the choice usually narrows to whether a blackwall, wide whitewall, or double-whitewall presentation best suits the car's restoration direction.

For many pre-war cars, sidewall treatment has a major effect on how formal or restrained the finished vehicle looks. Exact originality can vary by body style, market, and historical documentation, so owners seeking highly precise restoration results should compare tire appearance with marque references, surviving examples, and other vehicle-specific historical material before making the final selection.

Yes, correct tire fitment matters a great deal on a 1933 Nash Ambassador restoration. The 700-18 size influences the car's stance, wheel-to-tire proportion, and the visual balance that defines an early 1930s full-size automobile, so the wrong size or construction can change the car's appearance noticeably.

Fitment matters beyond appearance as well. Wheel diameter, suitable rim width, and the chosen tire's overall presentation all affect how authentic and usable the finished car feels, which is why owners should verify the actual wheels on the car and select a tire that supports both the restoration's visual goals and the vehicle's expected road use.

Yes, modifications can affect tire fitment on a 1933 Nash Ambassador even when the intended tire size remains 700-18. Replacement wheels, width changes, altered suspension height, brake conversions, or body repairs can all change how much room the tire has and whether a specific product is suitable.

That is why the car's actual setup should be checked before choosing among available 700-18 options. Wheel diameter and width should be measured, and steering and fender clearance should be inspected at full lock and through suspension movement, especially if the car has a long restoration history or parts sourced from outside its original configuration.

Before driving a 1933 Nash Ambassador on new tires, inspect the wheels for condition and correct sizing, make sure the tires are seated properly, and confirm that inflation is appropriate for the selected tire. It also helps to check for rubbing at the fenders, steering components, and suspension travel points.

A freshly mounted set of tires should be followed by a careful road check at moderate speed rather than an immediate long-distance trip. Pay attention to vibration, pull, unusual noise, or heat buildup, and recheck pressure and wheel fasteners after the first drive so the car starts its road use on a stable, thoroughly inspected foundation.

700-18 tires on a collector 1933 Nash Ambassador should be kept properly inflated, inspected regularly for cracking, cuts, bulges, and air loss, and protected from long periods of harsh sunlight, moisture, and ozone exposure. Collector cars often age their tires more through time and storage conditions than through mileage.

Routine inspection matters even when the car is driven only occasionally. Checking tread condition, sidewalls, valve stems, and wheel condition before each outing helps catch age-related problems early, and moving the car periodically or storing it carefully can reduce flat-spotting and other storage issues that are common with vintage bias-ply tires.
