I just picked up a 15 yukon xl. Getting ready to install new tires, wheels and leveling kit. Leveling kit is by daystar - 2 inch front and 3/4 rear. Black rhino Sierra 20x9 with +12 backspace wheels. Now I am trying to pick my tire size. I feel comfortable that 285x55x20 will work but am not sure that is agressuve enough. I want the avoid trimming and rubbing. Could I do a bigger tire without fear of rubbing??? Looking at the Nitto TG2. Please post picks of your ride if you have a similar setup.
