33x12.5x15 stock cranked up torsions.
Torsions maxed and a lot of rubbing. Go 33x10.50 or stick with 31 or 32s. BFG has this size in M/T and A/T. The 12.5 is too wide on stock rims, with offset rims it made it worse. Frame rubbing with stock 15x8 and outside with offset. Forklift test.
5.5" Tuff Country with 33x12.5x15 No body lift.
35x12.5x15 with Glassworks fenders 5.5TC lift. No body lift.
Most tire stores will test fit the tire for you. I tested size without adjusting torsions then they let me crank away. You will rub rear flares, I cut mine flush to door. Rub em till you get a good contact patch and trim till its gone. Flare is inch from metal. Front facia is easy to clearance, rear of stock front fenders can be worked without much being in the way. Get a good test of contact and trim little by little.
