Hi sorry I dont come on here often. Depends how big you want to go. The front of our expensive car runs kumho KL71 28 x 8.5 x 14 tyres on HQ sunraisers and bolts straight up. Floor pan will need a little bit of massaging to clear. My ute runs a more tradtional mud tyre in similar size but on 14" vn commy rims and clears fine. Cant go any bigger without major modifications to either rims (custom offset) or replace with different coilover setup.
