TIRE
Document Type and Number:
WIPO Patent Application WO/2017/022683
Kind Code:
A1
Abstract:
The present invention reduces tire vibration noise while maintaining ice performance during the rolling of a tire having a plurality of studs. A plurality of circumferential stud rows (6) are each configuring a plurality of six or more studs (5) sequentially arranged along the tire circumferential direction S. In each of the circumferential stud rows (6), T is the number of studs (5), L(n) is stud spacing, and La is the average value of the stud spacings L(n). The stud spacing L(n) satisfies a condition of 0.4 × La ≤ L(n) ≤ 1.7 × La. One or more specific stud spacings satisfying a condition of 1.1 × La ≤ L(n) ≤ 1.7 × La are included in the plurality of stud spacings of the circumferential stud rows (6), and are inconsecutive along the tire circumferential direction.
