    Abstract: Provided is a pneumatic tire having further improved ice performance achieved by narrow grooves. The pneumatic tire of the present invention is provided, in a tread, with land sections formed by partitioning the tread by grooves, and each of the land sections is provide with narrow grooves in a ground contact surface of the land section. The angle of tilt of the narrow grooves relative to the tire's circumferential direction is set to be larger in end regions located at both sides of a center region in a tire's lateral direction in each of the land sections than in the center region.

    Abstract: Provided is a tire exhibiting improved wear resistance, partial wear resistance, and traction performance on the wet road surface. The tire has block land portion arrays 5 defined on a tread portion 1. Between two block land portion arrays 5 located adjacent to each other while sandwiching a circumferential groove 2, a block land portions 4 constituting the block land portion arrays are arrange so as to be positionally displaced from each other, and a groove portion 6 located between the block land portions adjacent in the tire width direction extends obliquely with respect to tire width direction and the tire circumferential direction. At this time, a distance d2 between the block land portions adjacent in the tire width direction is shorter than a distance d1 between the block land portions adjacent in the circumferential direction. In the block land portion arrays 5 adjacent in the tire width direction, an inclined angle α of a side wall 9 of the block land portion 4 located on the groove portion 6 side with respect to the tire circumferential direction is larger than an inclined angle β of the other side wall 10 located on the opposite side to said groove portion 6 with respect to the tire circumferential direction.

    Abstract: In a tread part, a land part (block) partitioned by a main transverse groove is provided with a thin groove having a narrower groove width than the main transverse groove and extending in a tire width direction. On a groove lateral face which is one of opposing groove lateral faces of the thin groove, ridges projecting toward the other groove lateral face and extending in a depth direction of the thin groove are provided. A plural number of the ridges are provided in parallel to each other at intervals in a length direction of the thin groove, and an extending length in the depth direction is set up to include at least two kinds.

    Abstract: A pneumatic tire has an asymmetric tread pattern and an outboard tread edge and an inboard tread edge to be located outside and inside of a vehicle respectively. Inboard shoulder blocks have an axial width and outboard shoulder blocks have an axial width more than the axial width of the inboard shoulder blocks. The inboard and outboard shoulder blocks are each provided with a plurality of sipes. The sipes of each outboard shoulder block include a circumferential sipe as the axially outermost sipe. The circumferential sipe extends at an angle of not more than 10 degrees with respect to the tire circumferential direction. The outboard shoulder block has an axially outer sidewall of which surface is provided with a plurality of narrow buttress grooves extending radially inwardly from the outboard tread edge.

    Abstract: A pneumatic tire which prevents one-sided biased abrasion from being generated, the pneumatic tire having a non-directed rotational direction and comprises lug grooves 20 cutting across a land portion at a shoulder side of a tread portion 16 at both sides in a tire width direction. Each of the lug grooves 20 has a tapered groove portion 21 such that the groove width gradually becomes narrower such that a trapezoidal block portion 22 having a short side at the shoulder side as seen from a tire tread surface side is formed between the lug grooves 20 in a tire peripheral direction. The tapered groove portion 21 is formed so as to extend beyond a one quarter point Q from a tread end T. Accordingly, since in whichever direction the pneumatic tire 10 is rotated, a lug angle α of a trailing end near the one quarter point Q becomes 90 degrees or less, it is possible to prevent one-sided biased abrasion from being generated.

    Abstract: A heavy duty pneumatic tire comprises a tread portion provided with circumferentially continuous main grooves and lateral grooves to form blocks in circumferential rows. The main grooves include a pair of shoulder main grooves disposed one on each side of the tire equator so that the center line thereof is at a distance of 0.30 to 0.65 times one half of the tread width from the tire equator. The blocks include crown blocks disposed in a tread crown region between the shoulder main grooves, and shoulder blocks disposed in shoulder regions axially outside the shoulder main grooves. Each of the crown blocks and shoulder blocks is provided with at least one axially extending sipe.
