I have an 08 Tundra with 20" wheels. I woul dlike to put a more aggressive tire on, probably a BF Goodrich. What is the maximum tire I can go with to add a little lift without rubbing or any other mods. I currently have p275/55/20, I was thinking a p275/60 or 65 / 20.

You might have better luck in the Tundra section... ;)
