Wheels and tires
Winter tires
Winter tires provide more grip in snowy and icy conditions, and in consistently low temperatures.
You must use the same type of tire on all four wheels. Do not drive on winter tires with less than 4 mm of tread depth.
Note
We recommend using winter tires when the outside temperature consistently dips below 7°C. Choose tires with load index and speed rating that match the original equipment specifications.
Note
Always check the local regulations when using studded winter tires.
Note
Not all M+S rated tires provide sufficient performance under all winter conditions, and in some regions, they are not legal. For best performance, install tires featuring the 3-Peak Mountain Snowflake Symbol (3PMS) 
on their sidewalls.
