OK, the manual in one says to measure the MM of the tire height, and multiply by 3.14 (inital setting was something like 996 or something similar). Not being a math wiz, is this the circumference of the tire in MM? The other computer was roughly within 20 of the other computer for the setting.
Thanks :confused:
