You will need to use winter tyres when you plan to drive during the winter season. The winter season isn’t only snow and ice; it starts already as you get cold temperatures. Winter tyres are for winter use and are approved for winter use as they have fulfilled the performance tests required on snow. It is not enough that they have the M+S marking that indicates Mud and Snow, which is not tested and will have significantly worse properties than those that have passed the performance tests and thus have the three-peak mountain snowflake (3PMSF) symbol on the sidewall of the tyre.
