Ron, If you Google "tire size calculator" you will get what your'e looking for.

Then one member produced a program that would match tire sizes based on tire diameters, primarily to maintain the accuracy of the speedometer (if my memory serves me correctly). Does anyone still have this useful tool? Would they be kind enough to post for all club members? Thanks.
