Made in time switching to winter tires - a guarantee not only safe driving but also long-term operation of tires and fuel economy.
However, a variety of tire models often leads to the wrong choice, which can be avoided if an understanding of the types of winter tires.
Replacing summer tires for winter and vice versa -the inevitability with which every year facing almost every Russian driver. The main question is, when it is better to do. According to experts, it is best to change smb.'s Shoes in the car winter tires when the temperature reaches + 5-7S. But better to be safe even if the air warms up to + 10C, the probability of early morning frosts are always quite high. In order for the car skidded, quite sufficiently thin crust of ice. Therefore, it makes sense to have the temperature is lowered to 8-10S consider buying winter tires.
The lid and the temperature
Between them there is a connection, and quite silnaya-when cold weather tires becomes harder, its adhesion to the road surface is sharply reduced and the braking distance increases. At higher temperatures, the process is reversed: the tire softens, increase grip. However, there are also disadvantages: increased resistance and increases fuel consumption. Therefore, manufacturers using rubber in their products using various chemical compounds, reacts differently to the degree of warm air.
•; In winter tires softer tires - so whenuse it in the summer it is strongly softened, wear out quickly, there is a heavy feeling when steering. But already at zero elasticity increases, the car handles better.
•; Winter tires are made of hard rubber,which can be contacted with hot asphalt without decreasing its hardness. In cold conditions, the tire becomes rigidity, and the trip can turn into a slide.
•; There are all-weather "tires." It refers to the budget option. In summer, these tires wear out faster, and in the winter lose their elasticity, making it difficult to control the machine. The ideal temperature for these products - zero degrees.
When choosing tires you should pay attention totread pattern. If you plan to travel frequently on wet snow, the best approach aiming pattern that can divert slush aside. Omnidirectional pattern looks as if made of two. When installing a tire matter which side you put into it, and what outside. Tires with non-directional tread pattern is well suited to those who travel by contrast surface- for example, the dry asphalt, wet it.
Spikes: pros and cons
Spikes significantly increase the adhesion to the winterexpensive. What is more, the car's handling better- slip decreases, it becomes shorter braking distances. However, the operation of studded tires is advisable when permanent snow, ice on the roads. On dry pavement these tires will be worse braking, acceleration will be more sluggish. This occurs because of the reduction of adhesion to the road surface. In addition, "studding" very noisy. If you are right for studded tires, it is necessary to break in, drive for half an hour at a speed of 70-80 km / h on a level road.
