PNEUMATIC TYRE Russian patent published in 2018 - IPC B60C11/01 B60C9/20 B60C9/18 B60C13/00 B60C13/02 

FIELD: automotive industry.

SUBSTANCE: invention relates to the automotive industry. Pneumatic tire includes the tire body ply, breaker-strip ply located outside the tire body ply in the radial direction, rubber tread located outside the breaker-strip ply in the radial direction, rubber sidewalls located outside the tire body ply in the tire width direction, and protection elements located in zones passing from the tire-to-ground contact area edges to the places corresponding to the tire maximum width, and protruding from the tire profile. Protective elements have the rubber hardness Hs_p in the range 50≤Hs_p≤60, tensile strain at break Eb_p in the range 500 %≤Eb_p≤700 % and the elastic modulus E_p in the range 3.4 MPa≤E_p≤7.0 MPa.

EFFECT: increase in the tire durability.
