I have a 2007 Tahoe LT 4X4 with the stock 17" wheels. I have regular stock tires on it now, but want to get something a little more agressive. It is a 4X4 afterall. How big is the biggest tire I can fit on the stock 17" rim without having to lift the vehicle? Looking at maybe BFG A/T, Nitto, Toyo, or Cooper Zeon.
