level the frame and take a measurement from the frame to the ground (frame rails), jack your rear up to the frame (assuming the bumstops are cut off) with the wheels off, take a measurement from the center of the axle hub to the ground now subtract your first measurment from the second... that will give you a number that you need to times by 2, that will give you total tire diameter that you can run...use the tire size calculator to figure the rest
bad ass tire calculator
example:
1. frame rail to ground 6"2. rear jacked up to the frame, measurement from center of axle hub to the ground 203. 20" minus 6" = 14"4. 14" times 2 = 28"28" is the overall diameter tire size
note these are just numbers thrown in there for an example
