The first land portion has first transverse grooves such that each first transverse groove is extending inclined in first direction with respect to tire axial direction and completely across the first land portion, and first blocks formed between the first transverse grooves such that one or more first blocks have a first slot extending from first side surface of the first block on one side in the tire axial direction, a second slot extending from second side surface of the first block on the opposite side in the tire axial direction, a first sipe extending from the first slot and terminating within the first block, and a second sipe extending from the second slot and terminating within the first block without intersecting the first sipe.

A tire for a two-wheeled motor vehicle has a tread (2) including: a center region (Cr); a pair of middle regions (Mr) located on both sides of the center region (Cr); and a pair of inner shoulder regions (Sr) located on both sides of the middle regions (Mr). The tread (2) has provided therein: inner tilted grooves (10) having outer ends (10e) provided within the middle regions (Mr); and outer tilted grooves (11) having inner ends (11i) provided within the middle regions (Mr). The groove area ratio of the center region (Cr) is from 34% to 39%, the groove area ratio of the middle regions (Mr) is from 14% to 19%, and the groove area ratio of the inner shoulder regions (Sr) is from 14% to 19%.

The present technology provides a heavy duty pneumatic tire with a tread portion having a tread pattern including: a pair of circumferential primary grooves defined in a wave-like shape and extending in the tire circumferential direction; center lug grooves; center blocks; and circumferential secondary grooves extending in regions of the center blocks and open to the center lug grooves. The center lug grooves have two groove turning portions turned in a bend shape or a curved shape. The circumferential secondary grooves extend in an inclined manner relative to the tire circumferential direction. An inclination angle (.sub.4) of the circumferential secondary grooves relative to the tire circumferential direction is different from an inclination angle (.sub.1) of portions of the circumferential primary grooves relative to the tire circumferential direction, the portions extending toward the same side as a side in the tire width direction, toward which the circumferential secondary grooves are inclined.

A heavy-duty pneumatic tire includes a tread pattern including center lug grooves, shoulder lug grooves, a pair of circumferential primary grooves formed in wave-like shapes by alternately connecting ends of the center lug grooves and ends of the shoulder lug grooves and having a smaller width than the width of the shoulder lug grooves, center blocks defined by the center lug groove and the circumferential primary grooves, and a circumferential secondary groove extending in the tire circumferential direction so as to divide regions of the center blocks. The belt portion includes two or greater pairs of belts. The ratio of the width W8 of a belt having a smaller width in each of the belt pairs to the width W7 of a belt having a greater width is 0.75 or greater and 0.90 or less.

A tread part of a tire for a construction vehicle is partitioned in plural by circumferential grooves extending in a tire circumferential direction, and a tread end and a lateral groove. The lateral groove has, on at least one side of a tire equator line, an inflection point where the orientations of concavities and convexities relative to the tire circumferential direction change progressively outward in the tire width direction. The lateral groove extends from the inflection point toward one side in the tire circumferential direction and toward an outer side in the tire width direction, and further extends toward the other side in the tire circumferential direction and toward the outer side in the tire width direction, so as the lateral groove to have a bent groove part that forms a curved convex land portion with respect to the one side in the tire circumferential direction.

A tire includes primary inclined grooves and auxiliary inclined grooves. Each primary inclined groove has a first gently inclined portion and a first steeply inclined portion. Each auxiliary inclined groove has a second gently inclined portion and a second steeply inclined portion. Each primary inclined groove does not communicate with a circumferential groove on the tire equator line side and extends beyond a tread edge outward in a tire width direction. Each auxiliary inclined groove does not communicate with the circumferential groove on the tire equator line side, and does not reach the tread edge but terminates on the tire equator line side.

A pneumatic tire comprising on a tread surface 1 a plurality of blocks 7, wherein: the blocks have an inclined groove 43 formed thereon; the inclined groove has a connecting portion 43a connected to the circumferential main grooves, a wide-width portion 43b connected to the connecting portion, and a narrow-width portion 43c connected to the wide-width portion; the wide-width portion and the narrow-width portion have inclination angles with respect to the tire circumferential direction smaller than the connecting portion; the blocks have a sipe 52a formed thereon, the sipe having one end opening to the connecting portion and the other end opening to the circumferential main grooves; and the sipe has a bent portion.

In a pneumatic tire, a land portion is formed in a tread surface of a tread portion on an outermost side in a tire lateral direction by a circumferential groove extending in a tire circumferential direction, and a ground contact edge is present in the land portion. The land portion includes a plurality of lug grooves provided in the tire circumferential direction and intersecting the ground contact edge, and an intersecting narrow groove provided outward of the ground contact edge in the tire lateral direction and intersecting a lug groove of the plurality of lug grooves.

Provided is a motorcycle tire whose wear resistance and drainage performance are improved by refining the tread pattern.

The motorcycle tire includes: a tread section; and side wall sections and bead sections that continuously extend on both sides of the tread section, and the rotation direction of the motorcycle tire when fitted to a motorcycle is designated. In a tread section 10, first inclined main grooves 1 of a linear or curved shape which are inclined with respect to the tire circumferential direction, second inclined main grooves 2 of a linear or curved shape which are inclined in the same direction as the first inclined main grooves 1 but at a different angle, and shallow grooves 3 which are inclined in a different direction from the first inclined main grooves 1 and the second inclined main grooves 2 with respect to the tire circumferential direction are arranged, and the shallow grooves 3 are arranged only in a shoulder part.

A tire comprises a tread portion comprising a first tread portion defined between a tire equator C and a first tread edge. The first tread portion is provided with a crown main groove extending continuously and straight in a tire circumferential direction on a side of the tire equator C and oblique main grooves extending from the first tread edge toward the tire equator C to cross the crown main groove to form oblique land regions each defined between adjacent oblique main grooves. At least one oblique land region is provided with an inner oblique sub-groove extending from the oblique main groove and terminating within the oblique land region on an axially outer side of the crown main groove and an outer oblique sub-groove connecting between the oblique main grooves adjacent to both sides of the oblique land region on the axially outer side of the inner oblique sub-groove.
