I have a 95 S10 with 3.73s, and the kid that owned it before me bumped from 215/75 15s (728 revs per mile) stock to 225/60 16s (757 revs per mile).

Trying to achieve a 3.43 ratio would mean ~688 revs per mile. Taking my 225/60 16s to 225/75 16s gives me 689 revs per mile. Good 'nuff.

With 225/75 16s and 3.73s, I could then swap in actual 3.43 ring&pinion, which would then give me 633 revs per mile. Now we're talkin.
