Actually, Al Raab (Ma's Resins) makes beautiful Ford split-rim steel disc wheels for the 1-1/2 to 2-1/2 ton range of Ford trucks. The disc wheels were unchanged from 1930 through 1952.
The 1928-1929 Ford Model AA was significantly different and not interchangeable; they featured heavy duty wire spoke wheels.
The large commercial Fords used the same chassis, axles, springs, wheels and tires from 1930 through 1952. In 1930-1931 the Ford Model AA chassis was powered by the standard Model A 4-cylinder; in 1932 Ford began offering the flathead V8 as an option to the 4-cyl engine. Minor chassis changes began occurring around the end of the 30's and early 40's.
All American Models once marketed a resin rolling chassis suitable for the 1930-1940 era and it would pass most inspections for any Ford truck through 1952, other than the mechanical brakes earlier trucks had. The AAM chassis and wheels/tires have not been available for ten years or so. Later, Herb Deeks offered a resin early 30's chassis and wheels/tires, but it has not been available for about 5-7 years.
As mentioned, Ma's Resins currently offers beautiful resin wheels/tires (proper 6.00 x 20 size in scale) for the Ford AA, BB, and mid-30's through early 50's heavy commercial trucks.
