I have a 2009 Jeep Liberty...I will be changing the tires from 225/75/16 to 245/75/16 after the lift..I contacted a couple Jeep dealerships and they seem to think the computer can NOT be altered for the tire increase. If this is true what do people use?

The speedo is not adjustable in a KK due to federal laws,they can legally only change for OEM stock sizes that came on a KK.And sadly no one makes a aftermarket box like they do for the JK to adjust the speedo.
