I have a 2018 GMC 2500HD Duramax and want to replace the factory tires with 33 x 12.5 R 18 mud tires. I would like to know from someone who has done this if they will work without rubbing and without any modifications from stock.
I would appreciate any advise regarding wide mud tires.
Make sure to calculate the wheel offset change regarding any aftermarket wheels.
Wheel offset can make a big difference in tires clearances for rubbing.
Side Note: Stock wheels have a funky +44 offset not offered in most aftermarket wheels.
My apologies if you have already checked this.
