A buddy in my paramedic class was asking what the largest size of tire he could fit on his '99 Grand Cherokee? It is a full time 4x4 if that matters...it currently has 225/75/r16s and i told him that it didn't look like he could fit more that 245s...i'm just guessing..he still has stock rims also!! Thanx for any help

30x9.5 with the stock ride height. if he puts a 2" BB pucks in there then he can fit 31x10.5"
