At least I think its new: More and more alignment equipment is using degrees and minutes for specing toe during an alignment. Thats good because the angle doesnt change with the diameter of the wheel / tire. BUT...determining the desired angle doesnt see to be so simple.

Does anybody know what 1/16" - 1/8" equates to for a 26 inch tire on a 15 inch rim?

So far I THINK 14 minutes or about 0.25 of a degree equates to 1/16"

Anybody gone down this road?
