Severe weather conditions in the winter result in greater wear and other problems. To minimize the problems of winter driving, you should follow these suggestions:
WARNING - Driving with summer tires
Summer tires are equipped to provide the best driving performance on dry roads, varying according to specification.
Do not use summer tires at temperatures below 7°C (45°F) or when driving on snow or ice. At temperatures below 7°C (45°F), summer tires can lose elasticity, and therefore traction and braking power as well. Change the tires on your vehicle to winter or all-weather tires of the same size as the standard tires of the vehicle. Both types of tires are identified by the M+S (Mud and Snow) marking. Using summer tires at very cold temperatures could cause cracks to form, thereby damaging the tires permanently.
