I just bought a 1999 DII. The dealer that I am purchasing the truck from is putting on new tires of my choice, the ones on the truck are worn out. It has the 18" wheels on it an I am trying to figure out if I should go with the Nitto Terra Grapplers or the Michelin 4x4 XPC. Cost is not an option. I am thinking that I maybe should go with the XPC since the dealer is footing the bill. I have to special order the XPC and the Nitto are in stock at places. Any suggestions. I do plan on doing some basic off roading at some time.
