i am the recent new owner of a 97 passport and i was wondering if anyone could tell me what is the largest tire size i can run on the stock whell without a lift? i have heard 31"s will fit but i wanna make sure before i go out and buy tires that dont fit, LOL. any help would be greatly appreciated, thanks.

p.s. is this model considered the gen 1?

31's are the biggest you can go without a lift, that is what I have got. I like my BFG's mudders, I found the Pro Comp wear fast and the same foe super swampers.
