My rear rims are rotted out from calcium carbonate ballast. I want to buy new rims but everything I see for sale has loops for bolting to the wheel center. My rims have a solid raised area where the bolts go through to attach to the center. I'll attempt to attach pictures. My tire size is 12.4-28 apparently on 11" rims. Bolt center to center across the diameter is 24 1/4". adjacent bolts are 12 1/8" apart OC. Can anyone tell me if loop-bolted rims will work? Dealers don't seem willing to do any sort of research or measurement for me. Parts and shipping costs are too high to gamble on it.
