c15 tire rpm forumal

I am thinking of changing tire sizes, but i can't duplicate the current setting I have in my ECM. I thought I used before tire rpm, rear end ratio, final tranny ratio, another number I am not sure what its call. (Pulse per mile) maybe.

Answer this question I have this problem too

Is this a good question?

(engine rpm / tranny final ratio / rear axle ratio / tire revs per mile) x 60

example

1500 engine rpm, .73 trans final ratio, 3.36 rear end ratio, 510 XDN2 22.5LP revs per mile

(1500/.73/3.36/510) X 60 = 71.94 mph

hope this helps
