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.
