What size wheels are on a 1933 Ford?
The standard wheel diameter on most 1933 Ford passenger cars was 21 inches, typically paired with tires in the 4.50-21 to 4.75-21 range.
In this article, we examine the wheel sizes used on 1933 Fords, how they fit into the era’s engineering, and what collectors and restorers should know when evaluating a vintage Ford from that year.
Historical context: wheel sizes in the early 1930s
Automotive design in the early 1930s favored large, sturdy wheels and tall, narrow tires. Most American passenger cars of the period rode on 21-inch rims, with tire sizes commonly listed in the 4.50-21 to 4.75-21 range. Manufacturers often offered a few wheel styles—such as steel disc wheels or wire wheels—as options, but the fundamental diameter tended to stay consistent within a given model year.
What was standard for the 1933 Ford
For the 1933 Ford’s passenger lineup (including the popular 40-series/V‑8 models), the stock wheel diameter was 21 inches. The typical tire sizes paired with those wheels were in the 4.50-21 to 4.75-21 range, depending on the exact model and production period. Some export or special variants could have differed slightly, but 21 inches was the norm for U.S.-market passenger cars that year.
Variations and accessories
While the diameter generally stayed at 21 inches, buyers could opt for different rim styles such as wire wheels or steel disc wheels. Those choices affected appearance and, in some cases, handling characteristics, but they did not usually change the fundamental wheel diameter.
Restoration and verification tips
To verify wheel size on a 1933 Ford you own or are restoring, inspect the wheel for stamped markings on the hub or rim edge indicating the diameter (for example, 21). The tire sidewall often lists a size like 4.50-21 or 4.75-21, which confirms the wheel diameter and tire width. Cross-check with period catalogs or restoration references to ensure authenticity for your specific model and production date.
Summary
In summary, the typical wheel size for 1933 Ford passenger cars was 21 inches in diameter, with commonly used tires in the 4.50-21 to 4.75-21 range. Optional wheel styles such as wire or disc wheels existed, but the core size remained 21 inches. For restorers, confirming both wheel diameter and tire size on the exact vehicle helps preserve authenticity and ride characteristics.
