PNEUMATIC TYRE FOR MOBILE ENERGY MEANS Russian patent published in 2019 - IPC B60C9/07 B60C9/09 

FIELD: machine building.

SUBSTANCE: invention relates to the transport machine building, and mainly relates to the tractors driving wheels tires. Pneumatic tire includes sidewall, tread and sides, frame with several layers of parallel cord threads, composed of two half-layers. Said half-layers threads are arranged with a crossing in the sub-tread zone and are directed in the direction opposite to the preferential tire rotation direction. Each of the half-layers one edge is located in the sides zone, and the other is in the crown zone opposite part. In the sidewalls area the cord threads are located at an angle of 25–45° relative to the meridional direction. For each cord layer, as it approaches the tread, this edge approaches the tire equator. Distance between furthest from the tread half-layers ends is 90–95 % of the tire width, and for subsequent layers this distance is reduced by 5–7 %.

EFFECT: as a result, the tire life is increased due to the pressure difference between the tire equatorial and shoulder areas.
