Problems solved by technology

[0004] The lateral grooves and sipes that completely cross the land portion of the tread contribute to the improvement of on-snow performance, but tend to reduce the pattern rigidity of the tread portion, thereby deteriorating the steering stability on paved roads.

Embodiment Construction

[0048] Hereinafter, one embodiment of the present invention will be described based on the drawings.

[0049] figure 1 A developed view of the tread portion 2 of the tire 1 according to the present embodiment is shown. The tire of the present embodiment is configured as a pneumatic tire, for example. In this embodiment, an all-season tire that can be mounted on a passenger car or an SUV is shown as a preferable embodiment.

[0050] Such as figure 1 As shown, the tire has a tread portion 2 . The tread portion 2 is a portion in contact with the road surface, and various tread patterns are formed thereon. The tire 1 of the present embodiment has a left-right asymmetrical tread pattern. In order to maximize the characteristics of the tread pattern, the tire of the present embodiment has a designated orientation for mounting on a vehicle. The orientation to be mounted on the vehicle is displayed on the side wall portion of the tire (not shown) by, for example, characters and ...

Abstract

The present invention provides a tire. The handling stability and snow performance on the pavement can be balancedly improved. A pneumatic tire in which a tread portion (2) is divided into at least one land portion. The at least one land portion (6) is provided with a plurality of lug grooves (10) extending from the first end (61) of the land portion (6) and having an interruption end in the landportion (6), a first sipe (11) extending along the circumferential direction of the tire between the adjacent circumferential lug grooves (10) of the tire, a plurality of second sipe (12) extending from the first end (61) toward the first sipe (11), and a plurality of sipes (13) extending from the axial second end (61) of the land portion (6) toward the first sipe (11). The second sipe (12) and the third sipe (13) are configured not to intersect the lug grooves (10).

Description

technical field [0001] The present invention relates to a tire, and in detail, relates to a tire applicable as an all-season tire. Background technique [0002] For all-season tires, basic driving performance is required not only on paved roads but also on snowy roads. In order to improve the driving performance on slippery snow tracks, the tires are required to have greater snow column shearing force and road surface scraping effect. The snow column shearing force can be obtained by compressing the snow on the road surface with the transverse groove and shearing the snow. Therefore, in order to improve on-snow performance, it is effective to provide a plurality of long lateral grooves in the tread portion. In addition, the edges of the lateral grooves and sipe (that is, the ridge line where the tread tread intersects with the groove wall or sipe wall, the same applies hereinafter) improve traction by scraping the compacted snowy road. As a related technique, it is descri...
