I got my cherokee about 2 months ago, its almost brand new, 9000 miles. one of my close friends has one too, but with a 4.5 lift and 32 inch tires. weve gone off roading several times and i have had not too much of a problem keeping up with him, except for some of the deeper mud. i was considering new tires, bfg all terrains. but i dont think i lift is necessary yet for where i live in michigan. i may consider one a few years down the road but my jeep is so new id rather not do the lift yet. would there be much benefit to getting new tires and wheels? what size would i need?(i want close to the same size, yet a little beefier). -thanks
