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?

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 !

Were you guys, who went up in tire size, able to have the dealership recalibrate your speedometer?
