Seeing a lot of people on the side of the road with cut tires because they were driving with too low a tire pressure. The quick change to cold weather can drop tire pressure by up to 10 psi. For those already with low tire pressure, your rim could cut into the tire.
Had to help an elderly couple stuck on side of road with a sliced tire and one other that was badly mangled. Got the spare on and aired it up and they were able to limp to a tire store to get them both replaced.
