• Do all my tires have to be the same size?

Because of how 4 wheel drive systems work, it is best to always have the same diameter tires. If you only run in 2 wheel mode, you can get by with a different size tire front and rear.

With the use of QuadraTrac system on all V8 ZJs and on some of the I6 models, the same size tires are always required or you will destroy the viscous coupling system in the transfer case in very short time.
