I'm new to the Tundra and Tundra Talk. After looking around a bit I know this has been asked several times buy don't want to waste money. I have a 2013 Tundra CM 4x4 OK edition with stock 20's. It came with 275 55 and I want to go to a more aggressive tire so whats the biggest I can put on the stock wheels? Not really wanting to do a leveling kit right now so just stock. Any help is appreciated.
