I own an M814 with the stock 1100X20" rims. I want to replace the stock tires with T831 Firestones, size 12R 22.5. THe problem is that the tires fit on 9" wide rims, and the tire is 12" wide. Has anybody dueled out this combination? I know the 22.5" rims will fit the bolt hole pattern. My question is are the rims just to wide at 9" to fit the 5 ton axles?
