What is the largest tire size you guys have been able to comfortably fit on a 2017 Silverado 2500 HD 4x4 with 20" factory wheels?

This is what I ended up with, 275 65 20 but in Goodyear Durtrac's. The 285's that the Duratrac's come in are actually a bit shorter but a litter wider. I'd rather have the height and not so wide.

Those look great! I have been looking at that exact tire and size for my Denali. I would be interested in hearing how they work out and if there is any rubbing on bumps, etc.

Still good, ride as good or better than stock, of course a little more noise on the highway but not bad. I have gone up and down driveways full locked both ways and no rubbing..

I put on BFG KO2 285/65 20 with no rubbing on my 2017, extremely close but no rub at all...no crank to the Tbars... It amazes me that the same truck , built in the same factory can be different than one anther in ride height... I put allot of lifts on 2500 of all years and not one truck built in the same model year measured the same out of the box so to speak. Each one is a bit different.. Ranging From a quarter of inch to as much as three quarters of an inch..prior to installing any lift involves taking a stock ride height measurement from the ground to the bottom of the front fender lip...100's of recorded data points ....another useless fact brought to you by DZ302 !

That certainly would be explain all the differing opinions on what size will/will not fit! Thanks for the information!:thumb:

I was thinking about the same size but wasn't sure they would fit without any modifications (which I didn't want to do). I ended up installing 275/65X20 and have no rubbing issues and am very happy with the setup. I installed BFG KO2's...basically the exact same setup on my Denali HD as the one in the pic in this thread. Good to hear the 285/65 size would work too.
