I previously had a Honda Ridgeline that drove amazing in deep snow. I took my Y out on Friday, with about 4 to 6 inch's of snow on our roads. I felt pretty confident even with the current, stock 19" Continental ProContact RX's. I pressed the accelerator down and while the Y would slide just a little bit, the traction control immediately kicked in and it drove great.
Yesterday, we had about 20 inches of snow, and I stayed home. However, 1. Being ex-military having driven in Germany and Italy, and always being the neighbor who likes the challenge of driving in snow, and also being very wise about driving in snow, I have absolutely no worries driving in deep snow, it's just I don't trust other drivers, who just believe they can still drive 45 mph down our road. 2. I definitely would have gone out, if I had the snow tires I wanted. 3. I have some 18" wheels I plan on putting on this spring, and then my OEM 19" inch wheels will have dedicated winter or all weather tires on the Y.
I just had Xpel clear PPF full-front end, side fenders, mirrors, and I had them cut custom pieces for the rear wheel arches, installed. Tesla's PPF pieces, didn't seem like they would cover as much as I wanted and my Y was dirty from the drive to the installer, so I was able to show him exactly where I wanted the film.
