Bigger Tires?
When i buy 33's on 17" rims what do have to do in terms of speedometer and gear ratio recalibration.
do i need to recalibrate gear ratio's if im keeping my stock gears on my X?

If you are only going up to 33", the dealer should be able to flash your system for free. My dealer did it for me, I later added a superchips programmer for the increased performance, but you dont have to spend the money now if you dont want to.
