Re: Can A Change In Tire Dia. Be Calculated Accurately??
You would think by now, the way cars have advanced, they would have a speedometer adjustment on them for different size tires. Aftermarket tires are so popular today.
It wouldn't help on my old truck, but they could easily have a page on the U-Connect, listing all the different tire sizes that would clear the wheel wells on a Grand Cherokee. Just touch the tire size you installed, hit "APPLY", and your odometer and speedo would be dead nuts accurate. It could even automatically make adjustments based on the tire pressure you happen to be running at the time.
