Does anyone know what the biggest tire I can fit on a stock, 07, 4x4, LT with the stock 17" wheels? I have 255/65/17 right now with the stock tire, and would like my next set to be a little bigger and more aggressive tire like a BFG A/T or something like that. Dont want to have to lift it or do too much trimming. I would be open to removing the air dam if that is all that would be neccessary. Thx.
