Some folks use radius, axle to ground. But I have my doubts. Others use unladen diameter x Pi to calculate. I think I'll try rolling the truck one turn and compare to the two, so far as MPH calculations.
So far a matching diameters to ratios, some slippage is OK on loose stuff where 4x4 is needed. Some trucks had 4.10 on one end, 4.11 on the other on purpose. Others used as different mismatch, and 4x4 tractors often have a radical difference in tire sizes f/r.
