All tyres for passenger cars have two features which determine a whole lot of the characteristics. Everything depends on the rubber compound and tread pattern. Rubber should be optimized in terms of good characteristics of wet grip and high hysteresis. These qualities depend on the stiffness of the rubber. The chemical composition of rubber provides the necessary durability, elasticity and wear resistance in case of high-temperature of air and road surfaces in summer or, on the contrary, on snowy roads or in icy conditions in winter. And the unique tread pattern helps to remove dirt and water from under the wheels, ensures good contact area. Summer tread is, as a rule, asymmetrical and with narrow grooves and the winter pattern — with small lamellae.
In general, it is the tread pattern that determines the specific use of tyres — winter, summer and all-season tyres, as well as tyres for powerful high-speed low-profile vehicles. Passenger car tyres can be also divided by speed category.
However, chemists and designers in tyre industry are constantly working to improve wear resistance, gripping properties, handling, and reduce noise level, braking distance and fuel consumption, etc.
To extend the service life of tyres for passenger cars, general requirements shall be met. It is important to buy a full set of tyres. It is prohibited to use tyres of different types on the same axis. It is also important to maintain the same pressure in all wheels.
Do not use worn tyres. The minimum tread depth for passenger cars is 1.6 mm. To ensure even wear it is important to swap passenger tyres every 10-15 thousand km.
When buying tyres, pay attention to the date of production. They can be stored for three years without losing their properties.
