I have a 2015 Chevrolet LT 4x4 with 22 inch rims. It has a leveling kit in the front (not an all around lift). What is the biggest tire I can put on it without it rubbing. I am getting differing answers from tire dealerships. My front lift is 39 1/4 in the front and 38 7/16 in the rear (measuring from the ground). Thanks in advance, Daryl King
