you can put 285/75 tires on the stock chevy 16. DO NOT DO ANY CUTTING OR TRIMMING of your front end... if your t-bars are up you are all set... i would stay away from the firestones.... lots of friends with bad luck and bad wear.... I am a big fan of the Hankook Dynapro ATM... in the 285/75/16 they come standard load range E.... Great price as well! Under 800 most of the time and the sidewalls look awesome!
