The spec sheest says to use 11x28 rear tires. What is on the tractor is 13x28 and the new tires I bought are 13.,something x 28. Now I see I need new rims and am seeing everythig from 9" to 12" wide. Should I go with the 12" wide or keep looking?

thanx,
dan

An 11 x 28 tire is the same size as a newer 12.4 x 28. This is the OLD numbering system (pre 1958) and the new numbering system with a decimal point (1958 and newer).  A 12 x 28 tire is the same size as a newer 13.6 x 28. A 13 x 28 tire is the same as the newer 14.9 x 28. I would use an 11 inch wide or 12 inch wide rim for any of these tire sizes.

Whoah, that's getting complicated! Or at least confusing. 🤔

I would go with 12" wide. 13" rims are for 14.9 tires. So I"d think a 12" rim would be good for 13.x tires.

Allis used 12 inch rims on the WD-45 tractors, of which many had the optional 13 x 28/ 14.9 x 28 rubber on them from the factory. Allis also used 13 inch rims on thousands of D-17 tractors which had 14.9 x 28 as the standard tire and 16.9 x 28 as the option and used 13 inch rims on both sizes. I know tire size charts say this is wrong, but that's what they did.

Thanx Everyone. Between here and too much time on a computer, 12" is by far the right way to go with the new 13" tire. Appreciate the help...
