what's the biggest, widest offroad tires i can put on a 94 grand cherokee with 15" rims. Stock height and all. I was looking into the bfgoodrich ones. thanks!

 

On my 95ZJ the biggest I could go without a lift is 235/75/15. Bigger than that would rub. Some have had luck running 30x9.50 but I did not.

 

I've got 30s w/ stock height with a little rubbing when the wheel is turned all the way.

 

also, although tires may have the same size written in their measurements, not all brands will be the same size. for example, a bf goodrich 30" tire may be bigger than a Goodyear or the other way around. I have had 32" swampers that were taller than 33" mtrs. I have Michelins and they don't rub but I think other brands that are more of an all terrain tire have taller tread.

 

I have BFG 30s on my 95 ZJ with stock wheels and no lift, no rub here.
