Pneumatic tire

Abstract

Provided is a pneumatic tire that, even when the tire has an asymmetric pattern, enables uniformity and weight balance of the tire to be satisfactorily maintained while improving traveling performance in a unpaved road. Side blocks 30 are respectively provided to side regions adjacent to the outside in the tire width direction of the outermost end section of a tread part 1 in the tire width direction. The number N1 and the total area SS1 of the side blocks 30 provided to a first side region positioned on one side in the tire width direction, the number N2 and the total area SS2 of the side blocks 30 provided to a second side region positioned on the other side in the tire width direction, the land section area TS1 in a first tread region positioned on the first side region side of the tread part 1, and the land section area TS2 in a second tread region positioned on the second side region side of the tread part 1 satisfy the relationships of N1>N2 and TS1>TS2, and 0.95 <= (SS1xTS1) / (SS2xTS2) <= 1.05.

Description

technical field [0001] The present invention relates to a pneumatic tire suitable as a tire for running on unpaved roads, and more specifically, to a pneumatic tire capable of improving running performance on unpaved roads while maintaining good uniformity and tire weight balance. Background technique [0002] In pneumatic tires intended to run on unpaved roads such as uneven ground, muddy ground, snowy roads, sandy ground, rocky ground, etc., a tread pattern with a large groove area and mainly horizontal grooves and blocks with many edge components is generally used. . In addition, a side block is provided in a sidewall region on the outer side in the tire width direction of the shoulder block located at the outermost side in the tire width direction of the tread portion. In such tires, the traction performance is obtained by biting mud, snow, sand, stones, rocks, etc. on the road surface by using the above-mentioned transverse grooves and blocks, and the mud, snow, sand, ...

AI Technical Summary

Problems solved by technology

Tires with an asymmetrical pattern tend to tend to deteriorate in uniformity and weight balance due to their asymmetrical construction

In particular, when an asymmetric structure is adopted in a tire having side blocks in the sidewall region as described above, not only the asymmetric structure in the tread portion may affect uniformity and weight balance, but also the asymmetry in the sidewall region The structure may also affect the uniformity and weight balance, so the influence on the uniformity and weight balance caused by the asymmetrical structure may become significant
