Well actually i did find that a 31 would work. But i'm actually more interested in knowing possibly a brand and a size someone may have used that worked for sure. I see some Kumho's that at 31x10.5 but i think that may be too wide for the stock wheels with no spacers. Correct me if i'm wrong. Also, I believe I saw a BFG that was 31x9.5 which seems a little bit more likely to work.
