What is actual gear ratio with 37" tires and 4.10 gears

What will the gear ratio come out to with 37" tires along with 4.10 gears? What rpm would that put me at around 70mph?

(Stock tires OD / New tire OD ) * rear end or RPM

(30/37) * 4.10 = 3.32

stock tires (265/70/17) are around 31.6" tall which will make that equation go to about a 3.5

This calculator says about 3.50, with the 4.10 and 37s.

His gear ratio with a 4.10 to 1 gear is 4.10 to 1. That can't change unless he swaps gear sets

Now if you're talking overall ratio....

yes he is talking effective ratio. he will have 4.10's but they will be like 3.5's with taller tires
