Recently added 37"s to my rig.I forgot the multiple for figuring actual mileage and speed.Some help? Thanks,Mark.

compared to what tire? stock?

The simplest way is to divide the new (bigger) tire diameter by the old (smaller)tire diameter and multiply that by the speed shown (assuming it was correct for the old tire). It is a linear relationship.

Thanks. Seemed to me there was a site that had a computer to figure all variables and rim/tire combos? Anyone?

Here is a link to help you with the math. This is at Discount tires web site, and could prove to be very helpful.

Thanks for the replys fellas.Im running Toyo's,and loving 'em so far.No pics to share,it does give the Dodge a bit more of an aggressive stance though.
