I have a 2020 Ranger 4x4, if you're using the tires that came on it (either the all-seasons, or "all-terrain" for some packages), replace them with snow tires for the winter. The tires they put on at the factory are fine for 3 season driving, but they perform very poorly in the snow. A few bags of sand in the back of the bed doesn't hurt either, as others have suggested. Happy holidays and stay safe!
