What is the correct tire pressure for a winter tire?

Nokian Tyres has tested the winter tire pressures for most car models. The indication has been that the number should be 0,2 bar (20kpa) higher than the recommended summer tire pressure. This is due to to different construction in a winter tire and the effect of cold to the pressure. You can check your vehicle’s manual for the recommended tire pressure. Note: Always measure pressure when the tires are cold.
