Tire Revs??

[BocaCobra03]

Hey guys...I want to change the Tire Revs with my SCT Livewire to match up with the tires I am running...Any idea what the tire revs are on....
37x13.50 Kumho Road Venture MTs on 22" Rims would be? One sight I found I came up with 545 Revs....This sound correct? Bigger the tire and rim the lower the tire rev # correct?
Thanks

rim has no damn effect on it at all. and there is not perfect number. each tire is different, differnt air pressure, load...
best bet is do this
make a mark on your tire, and a mark on the ground in line with the mark on your tire. rotate your tire three revolutions forward and measure. divide by three. this is your cicumference.
if your tire was a true 37" it would be approx 116-117" this would mean your tire makes approx 546 revs.
you figure this number by going like this, a mile is 5280 feet, or 63360 inches. your tire covers 116" in 1 rotation, so divide 63360 by 116 and that is how many revs per mile. my 37's measured 35.4, so i got 565 revs per mile.

The tire manufacturer can tell the Rev/mile

and here is a nifty way to calculate it:

those are only going to be estimates, rim width, air pressure and vehicle weight are all going to effect it.

should be 560 thats what the toyo 37 is. the kuhmo is .02 smaller (37.0 toyo vs 36.8 kuhmo),
