Although all-season M+S tires provide better winter traction than summer tires, they generally fail to provide the same levels of cold-weather performance as winter tires. Paying attention to speed Always observe the maximum permissible speed for the winter tires, otherwise tire damage may occur, which can result in accidents.< Storage Store wheels and tires in a cool, dry place with as little exposure to light as possible. Always protect tires against all contact with oil, grease and fuels. Do not exceed the maximum tire inflation pressure indicated on the side wall of the tire.
