Im not an expert by any means but here is what I have found out while running 33X12.5X15s. 6-10 miles an hour off depending on speed (Example 40 = 46, 55=65) and my odometer is off .2 tenths [img]images/graemlins/censor.gif[/img] of a mile. I dont know how it changes when you put 31s on but I guess I will find out sometime soon. Hope that helps.
