Yesterday we had a snow/ freezing rain mix come down and I had to go pick up the wife after work. Part of the trip is going up the side of a small mountain on which it performed flawlessly while I had the vehicle in 4WD Auto. In fact, I actually passed several vehicles which were stuck trying to go up the mountain, a majority of those fwd sedans. I can't say I was surprised but the way those tires handled the mess put me at ease for my wife as she is the one who normally drives the truck daily. I have stock size 18" KO2's on mine aired to 40 psi and I do have the non-slip differential. We can't wait to take this on the beach like we did with our 2016.
