JeepcoMJ Posted January 12, 2008 Posted January 12, 2008 I put 31/10.5/15 on my mj it is stock other than the oversized tires how much would that throw my speedometer off? should be approximately 3mph lower than what you're going...that's what mine is. edit: your speedometer should read 3mph LOWER than the speed at which you are traveling at that given point in time just to clarify what I meant
