Some people say, no tire revolution was the development of the world automobile industry. And in 1946 by the Michelin company invented radial tire, to tire industry revolution, is the landmark. Radial tire is available, not only for modern traffic plays a decisive influence, at the same time, but also to human life brought about by the bright colors. As of now, meridian tire has occupied domestic and foreign tire market absolutely mainstream.

        What is a radial tire

        Radial tire carcass and tread center line forms a 90 degree angle or close to 90 degrees is arranged, and ply tire of meridian section, much like Earth's meridian, so called radial tire. Because ply this arrangement characteristics, making the radial tire ply rating than ordinary tire can be reduced to about 40%-50%. Radial tire circumferential direction to contact the rubber alone, so in order to support the road caused large tangential force, to improve the tire stiffness, tire also has several layers of cord and meridional section at a larger angle ( angle of 70-75 ), high strength, not easy to stretch the circumferential annular similar buffer strips belt. Belt generally uses the high strength, tensile deformation is small fabric cord ( such as glass fiber, polyamide fiber ) or steel wire fabric manufacturing. The simplest method is to distinguish from the tire specification code. For example: 185 / 60 R 1584 H tires, wherein the" R" stands for radial tyre.

        What are the advantages of radial tire：

        Rolling resistance of small, fuel saving : as a belt, a tread rear tire crown tangential deformation and slip than ordinary tire will be much smaller, and the meridian tyre side thin, radial deformation recovery soon. These two characteristics is helpful for reducing tire wear, reduce rolling resistance. Experiments prove that the meridian tire rolling resistance than ordinary tire 20% ~ 30%, 5% ~ 10% of the fuel can be saved.

        Tread wear resistance, long service life: rolling, a tread surface deformation and fox, slip, deformation to slip, slip aggravate tread wear. As a result of radial tire tread stiffness, small deformation, almost no slip, in addition the crown ground area is large, the unit pressure is small and uniform, so that the tread abrasion. Test proves that the radial tyre service life than diagonal tire rises 30% ~ 40%.

        Elastic, a buffer is good: as the meridian tire cord radial arrangement, so when the wheel rotates, the tire is perpendicular to the ground deformation than the tire carcass big, soft, good elasticity, therefore improving the vehicle ride comfort.

        Anti prick ability: radial tire with rigid belt, so greatly enhanced tread penetrating resistance ability, reducing the tire burst risk, improve the driving safety.

        Adhesion: radial tire in driving ground area is large, at the same time as the belt layer, ground pressure distribution is uniform, thereby increasing the adhesion, reducing the sideslip phenomenon.
