Formula is:
63360/(Tire Diameter x Pi)

NOTE: This is TIRE diameter, not WHEEL.

27" tire sound right?

I left mine at default.. using the 20" stock foundry wheels.. What would this setting affect?

You should check the specs of the tire on the manufacturer website to see the overall tire height. Each tire is different, but sounds about right for a 245/40/19.


But I imagine that's your front tire? What matters is the rear tires.

That is the rear tire...When I look up the tire...the diameter says 26.7" so I think I am right on
