How to choose the tires correctly?
Sooner or later every driver has to decide which type of tire he would like to mount on his vehicle, and everybody comes up to this question in different ways. Someone prefers the tires that are cheaper and hopes that everything will be in order. Other, more conscious people first of all find out what are the most extreme conditions the car will be operated in. Seasonal factors have an important role in the behavior of the tire in different climatic conditions.
In winter every driver should be concerned about icy asphalt, snow-covered roads, slippery snow, etc. In order for the car to feel confident, the manufacturers of winter tires take into account all the hazardous factors of the winter weather and supply the tires with the latest developments to avoid skidding and elongation of the braking distance and to ensure the grip increase. The modern winter tire could have the following different "armament" components: studs of various shapes and designs, especially shaped lamellae made from special rubber composition which remains soft under sub-zero temperatures. Winter tires have a much more aggressive tread pattern than the summer ones. As a rule, a special marking is put on the sidewall of the tire to indicate it belongs to the winter type: winter - winter, M+S (from English words Mud and Snow).
In summer the most dangerous thing is the aquaplaning when the car glides over the road surface and becomes almost uncontrollable. Besides any wet road could be a danger no matter whether it's a heavy shower or a just little rain. To counteract the aquaplaning and wet roads the manufacturers produce tires with a dedicated tread pattern which could efficiently draw the water out through a variety deferent grooves.
The special marking is put on the sidewalls of some tires indicating that the given tire could be used in rain conditions, e.g. Aqua or Rain. In the same time the absence of such marks doesn't mean that this tire is not suitable for use under wet conditions.
