The quality of the contact the vehicle has with the road must be high and in the heat of summer, and in the dead of winter. That is why there are winter tires and summer. About the need for proper seasonal use of car tires says a lot. Everyone knows that when the temperature of ambient air passing up or down through the mark at 70, the car should be "change" in the tires appropriate to the season. But how to distinguish summer from winter tires? Don't believe me, see for yourself by reading the publication to the end.

Physical and chemical properties

Winter tires differ from summer to the touch – it is much softer, with the percentage of rubber is higher than that of tires designed for summer use. While driving at low temperatures, winter tires warms up, becoming soft and elastic, providing a secure grip. In the case of using winter tires in the summer, she begins to literally "melt", being exposed to increased wear. Summer tires, on the contrary, have the ability to cool off when riding in conditions of high ambient temperature while retaining its rigidity and shape. In the cold season, summer tires becomes very hard, causing the contact area between the tyre and the road surface is significantly reduced, impairing the stability of the vehicle on the road and increasing the likelihood of you losing control of them.

Shape and tread pattern

The main feature of winter tyres from summer is the presence on the surface of them overshoes spikes. In this case, there is no doubt, winter tires. But if studless tires? Many will tell you the shape and tread pattern. Winter tires, unlike the summer, has deeper tread. The tread pattern of winter tires has a diagonal structure with a well-developed network of canals for water drainage, resulting in very similar to the silhouette of a Christmas tree (European tyres) or consists of a large number of diamond-shaped figures, placed apart at a distance (Scandinavian type). The presence of a large number of fine slits (sipes) in the tread surface and powerful lugs on the periphery unerringly pointing to the fact that this tyre is designed for use in winter. As for summer tires, the tread projections it has a large area, the picture is less convoluted in shape, and lamellae on the surface of the tread either missing entirely or present in insignificant amounts.

Labeling, and the legend

On the side of winter tyres mandatory marked symbols "M+S", "M&S", "MS", "Mud+Snow" or "Winter". Often a symbol of winter tires in the form of the snowflake icon. If such designations on the bus there or there will be an icon in the form of the sun, this tyre is a summer. There are all-season tires marked "Allweather" or "Anyseason". These tires are designed for operation in climate conditions with minimal temperature changes and are more suitable for use in Western or southern Europe. Good luck to you! No nail, no wand!
