I found this link where they claim benefits to mileage, reduced wear, better shift points, etc. Do you guys think these claims are legit? Quote Something else I forgot to add. If and when you change to a bigger tire, your speedometer and odometer will be off. I used a TruSpeed Speedometer Recalibrator. It corrected my speedo when I went from 31" to 33". If I decide to go up to 35" tires I can adjust again to correct the speedometer without extra expense. 99 XJ, 4.5" RE lift, SYE+driveshaft, 31" BFG ATs, Warn rear bumper+tire carrier, JCR front bumper and sliders Re: Speedo recalibration - any benefits?

I see no reason to spend more than that.. Big Jim <img src="/forums/images/graemlins/pfft.gif" alt="" /> professional bovine relocation specialist Re: Speedo recalibration - any benefits?

The only benefit would be not racking up extra milage if you've regeared lower than stock for ins. or resale purposes (after figuring in your bigger tire size), or you can't figure your speed in your head on the road. I haven't bothered. <img src="/forums/images/graemlins/rolleyes.gif" alt="" /> 97tj, Shaved Ford 9 rear, 4:10's, New 35x12.5 BFG KM2's to test!, Warn x8000i, ARB's, Quick Disco's, Hand Throttle, & it's my DD.
