In winter road conditions winter tyres will considerably improve the car's handling. Due to their type of construction (width, rubber compound, tread pattern), summer tyres give less grip on ice and snow.
Winter tyres must be fitted on all four wheels.
Only use winter tyres of the correct type approved for your vehicle.
Please note that the maximum permissible speed for winter tyres may be lower than for summer tyres WARNING!. Your specialist retailer can advise you of the maximum speed for your tyres.
After fitting the wheels you must always check the tyre pressures
►Link.
Winter tyres lose their effectiveness when the tread is worn down to a depth of 4 mm. The performance of winter tyres is also severely impaired by ageing, even if the tread is still much deeper than 4 mm.
- Never exceed the maximum approved speed for your tyres. This causes the tyres to overheat and can even result in a blow-out – risk of accident!
- Always adapt your driving style to the prevailing road and traffic conditions. Drive carefully and reduce your speed on icy or slippery roads. Even winter tyres lose their grip on black ice.
For the sake of the environment
Summer tyres should be fitted again as soon as possible; they give better handling on roads which are free of snow and ice. They are quieter, do not wear so quickly and reduce fuel consumption.
Note
All-weather tyres can also be used instead of winter tyres. Please note that winter tyres with the 
symbol are required by law during the winter season in some countries.
