More air in your winter tires
Temperature has a significant impact on tyre pressurisation. For summer tires, we recommend using the vehicle manufacturer’s suggested tyre pressure. For winter tires, you should inflate the tires to 0.2 bar above the summer tyre recommendation. The temperature in a warm garage can be up to 30 ˚C higher than outside. If the tyre pressure is measured inside, it will be too low for outside temperatures.
Example: The temperature in the garage is +20 ˚C, while the outside temperature is -10˚ C à If the pressure is adjusted in the garage, the pressure added to the tires must be 30 kPa (0.3 bar) higher than the recommended value to ensure a correct pressure level outside.
More safety and longer service life
In addition to correct tyre pressure, drivers should also ensure that uni-directional tires are correctly installed on the car. The arrow on the sidewall indicates the rolling direction.
To prolong the lifetime of the tires, front and rear tires can be changed from one axle to another every 5,000–10,000 kilometres. As a result, the tires will wear evenly and show smaller differences in wear.
Tires marked M+S (intended for winter use) should be carefully broken in. For the first 500 kilometres (310 miles), avoid sudden acceleration and braking. A gentle break-in improves the durability of studding: the studs will fit securely into place and stay on the tires.
