Re: Tire Question
It goes deeper than that with the Quadradrive system. You can never put different diameter tires on or it will lock up. Even one size different. But more so, you cant replace just two of the same type of tire, lets say. The diameter difference of a new tire and one that is half worn say, is enough to cause the transfer case to burn up. You must put 4 new tires of same size and type and rotate them every 2K to be on the safe side.
My WJ with 26K on the ODO had to have the transfer case replaced when I got it because the previous owner didnt rotate the tires and I think either bought only two or rotated the spare into the mix. Luckily I had bought an extended warranty. I have rotated my new set of tires and have had no issues.
