I have a '15 GMC Denali 2500 Dmax with the 20" stock wheels and 265/60-20 Goodyears. I need new tires and was wanting to size up a little but the next E rated tire in the Michelin Defender is 285/60-20. It's only an inch taller, an inch wider but my tire guy says from what he has heard that I should stay with the 265/60 because of rubbing issues if I don't turn up the torsion keys and lift the rear. The wheel well does look too small for the truck. What is your opinions and experience?
