TYRE Russian patent published in 2019 - IPC B60C11/16 

FIELD: automotive industry.

SUBSTANCE: invention relates to the automotive industry. Tire contains a plurality of annular rows (6) formed by plurality of studs (5) of at least six successively in the circumferential direction S of the tire located studs. In each of ring rows (6) with the number of T studs (5), the interval L(n) between the spikes in the tire circumferential direction satisfies the relation 0.4×La ≤ L(n) ≤ 1.7×La, where La is the average of the spacing interval L(n). Among the many intervals between the spikes in ring rows (6) there is one or several special intervals that satisfy the relation 1.1×La ≤ L(n) ≤ 1.7×La, in the tire circumferential direction, the arrangement of the special intervals is not continuous.

EFFECT: reduction of vibration noise of a studded tire while maintaining its characteristics on the ice during its rotation.
