Pneumatic is one of the three main elements of active vehicle safety. Its development started as a rubberized part of a wooden wheel, then the present shape got the development of the tube first as a diagonal and then as a radial pneumatic, or today's standard pneumatic radial is without the radius. Radial tires are squeezed out of everyday use diagonal due to the many advantages they possess. Also every new generation of tires has significantly better characteristics than the previous one. Tire maintenance is not demanding, and the durability of the tire depends on internal pressure, driving mode and driver, and the condition of the carriageway and car. The use of tires outside of the anticipated annual seasons reduces safety. The marking marks the pneumatic in several grades. Tests for the correct tire selection are supported. Tests are conducted on dry substrates, rain and snow, bringing pneumatic to their limits.
