Hey guys I'm lookig for some help here please, I have a 03 4x4 super crew and i purchased a set of the Harley Davidson edition wheels I also purchased a set of Kumho ECSTA STX 275/45/VR20. My question is do I now have to recalibrate everything (speedometer, odometer, ABS, cruise control)?

 

No, you do not have to recalibrate anything. If the new 275/45-20's are a different height than your OEM tires, you speedometer/odometer will be off slightly, but that is the only problem you will have. I installed a 3 inch taller tire on my Screw when I purchased it and my speedo is off 5mph at 60mph.

 

Thanks for the info, I was worriied I was adding alot of extra miles to my truck due to the smaller tire height(2 inches).

 

if ur really worried about your speedo/odometer being off you can buy a hypertech or equivalent brand programmer and u can recalibrate it

or you can go to a dealer......but i was told only certain dealers have the equipment to do it

either way it will cost u at least $175-$350
