I am curios about this tire size and gear ratio, I run 255/60/15 with
3:55 gears, I run at 2000rpm at 70 my tires are'nt 31" tall so how can I
be turning the same rpm as you. how far off is one of our speedo's?
also anyone know how to tell if you have a suregrip in the rear without
a teardown. Thanks Dan
