Two times a year it is necessary to change tires on the favourite car. It as change of footwear in the winter – winter, in the summer – summer. Time for summer tires has now come. Differences of winter and summer tires as a part of rubber, a framework design, a tread pattern.
Summer tires are used only when on roads any more doesn't remain snow and ice.
At summer rubber the best clutch with dry asphalt, for the account big a useful area of a stain of contact piece.
By manufacture of summer rubber softer rubber which is lost the elasticity at influence on it in low temperatures (below 5-7 degrees) is applied, and it will cause the raised danger on road.
In the summer during a heavy rain between a wheel and road the water chock is formed, the tire loses contact piece to a road carpet and starts to slide on water, and the car becomes the uncontrollable. This phenomenon carries the name planning. And to dewater a contact piece stain on summer tires do 2-3 deep longitudinal flutes and set diagonal more small. Flutes usually less wide, than on winter tires, and transition from a tread to side piece more sloping.
It is necessary to carry its wear resistance, profitability to advantages of summer rubber, they less noisy, than winter tires.
And the main rule – all wheels should be one seasonal prevalence. Also it is desirable, that they were from one manufacturer as tires of different manufacturers have also different technical characteristics, and it can negatively affect degree of roadability the car.
