October 28, 2014When it comes to winter tires, many drivers think of is to use snow tires, winter tires actually understand this wrong, because the definition of winter tires is less than the tire is suitable for use at a temperature of 7 Ã¢â€žÆ’, not specific snow tires. In fact, winter tires are available in three sizes, according to road surface skid resistance can be divided into jagged tires, snow tires and stud tires.
Normal pressure winter tires and summer tires, the best advice is the reference value of the car manufacturers. But the point to note is that winter temperature measured tire pressure will have some impact. The lower the temperature, the measured tire pressure will be low. Therefore recommended to measure the tire pressure at ambient temperature conditions.
Some car owners in order to save costs, the replacement after winter only two winter tires on the drive wheels, everyone knows, this is a very dangerous act. Because the car at high speed steering, only two snow tires before the car will exacerbate the phenomenon of understeer, then drove four seasons tire grip due to lack of grip and appear more serious than usual oversteer, so that the use of winter tires but more danger. So for safety, winter tires must replace the use of four together.
Changed four tires, but only the use of a winter, many owners feel that it does not pay, will usually continue to use it. Well, winter tires can be used in other seasons it?
In fact, this method is not desirable. Because winter tires for cars to better control of the vehicle, in the beginning of the design will choose a relatively soft material, and in order to secure a top speed of winter tire design is also much lower than the all-season tires. So, if you use winter tires in the summer, then winter tires not only increase braking distance, wear a top speed will be relatively fast and the tires will affect driving. Therefore, the best winter tires used only in the winter.
