So I took it to the Local Jeep Dealership, and they tried to re calibrate the speedometer for my new tires (245/70/17) and after 2 hours they came back saying they couldn't do it. They said the Pinion would only go so low, then reset to the factory default. They apparently tried multiple times...
He told me they set it to the lowest they could get it (which is less than half of what it should be with the new tires) and didn't charge me anything for it. I tried using my GPS to see how much better it was, but it still looked to be about 3mph off.
I don't care about the speedometer as much as the odometer displaying the wrong miles.
Any thoughts? Its not like I upgraded to HUGE tires, but even if I did...come on its Jeep...you would think it should be possible??
