HIGH-CAPACITY TIRE Russian patent published in 2015 - IPC B60C11/12 B60C11/11 

FIELD: transport.

SUBSTANCE: invention relates to automotive industry, particularly, to high-capacity tires. Tire comprises tread with blocs each being provided with zigzag-like blade made at the surface of contact with soil. Relationship between bloc length A measured in straight line crossing the centre of gravity of said contact surface and bloc maximum width (B) making the axial spacing between the most remote edges of said contact surface varies from 0.8 to 1.7. Said zigzag blade is located at central area extending from the centre of gravity of said contact surface on both sides of lengthwise direction through 25% of block length (A). Said zigzag-blade consists of two straight larger length sections extending axially inward from both sides of the blocs in the tire axial direction. Besides, it includes straight section of smaller length extending between inner ends of said larger-length sections so that lengthwise spacing between said most remote ends of said blade varies from 10 to 35% of bloc length (A).

EFFECT: reduced stepwise wear at sufficient road grip.
