Why you cannot drive in winter on the summer tires and vice-versa?
You probably have heard about people who drive in winter on the summer tires. And, according to their assurances, "in principle, you can go such way". But the question arises: is it possible to drive in winter on summer tires? To begin with, the newly sold cars are usually equipped with "all-season" tires. The nuance is that the climate is different in different countries.
First of all the manufacturers use the different rubber composition for tires of summer and winter type. Everyone who had driven on the "adhesive" tires (winter tires without studs) could notice the difference, when one changes the tires and the noise suddenly does disappear. The rubber used in the summer tires is more rigid, while the winter tires manufacturers use the softer type. In the cold (below 0) the summer tires sharply lose their elasticity which could become a cause of the poor grip. The tread becomes more rigid and the traction coefficient reduces that leads to the lengthening of the braking path.
There is a certain type of drivers who prefer to use the winter tires in summer. It is worth to know that in this case the winter tires wear out much more quicker. The winter tire due its rolling resistance on dry (sometimes even hot) asphalt could produce a very loud noise, have a bad influence on the fuel consumption level and affect the vehicle handling.
