Tire/rev calculator

I got new tires and a new size today. I need to find that rev calculator so I can program it into my SCTXCal

Thanks to anyone that can point me in the right directions

I went with 285/65/18 from 270/75/18

try this:

Tire Calculator

Your new tires have 619 revs per mile

Thanks Man, can you reprogram the stock setting to show the correct tire size?

I don't think so, but you can call your tuner and ask maybe. I think stock is stock, just the program your Xcal removed from your truck and stored it before uploading your performance tunes.
