Speedometer Recalibration in the WIKI.

There is not a standard cal number for any size tire. All tire manufactures make there tires a little different. For example a 265/75 will be a little different height in a Goodyear than it will with a Cooper. You need to do the rolling measurement to get the height or your number will be a little off. I did the rolling measurement very carefully, calculated my number and my speedo is dead on.
