FIELD: motor industry.
SUBSTANCE: invention relates to automotive industry. Tyer comprises radial external peripheral side of crown of frame inclined breaker containing inclined breaker layers, with inclination angle relative to cord tire circular direction of fibres in range of 35° -90°, annular breaker containing inclined breaker layers extending in tyre circumference and tread located outside annular belts in tyre radial direction. Circular breaker comprises area with high hardness across tyre equator, in which stiffness in circular direction per unit width exceeds that in any point of other regions. Circular stiffness per unit width is constant in other areas in tyre width or increases towards area with high hardness.
EFFECT: technical result is improved noise characteristics while maintaining stability of steering and rolling resistance.
