A pneumatic tire includes a tread portion provided with a shoulder main groove and a crown main groove to form a middle land portion therebetween. The middle land portion is provided with a first middle lug groove including a first groove wall and a second groove wall, wherein the first groove wall includes a protrusion protruding toward the second groove wall on the side of the shoulder main groove. The protrusion includes a front wall located so as to form a sipe portion between the front wall and the second groove wall, a top wall, a first lateral wall located axially outward of the front wall and a second lateral wall located axially inward of the front wall. The front wall is configured to a triangular shape.

A tire comprises a tread portion 2. The tread portion 2 comprises a plurality of oblique grooves 10 extending obliquely from a first tread edge Te1 positioned on one side in a tire axial direction toward a tire equator C, and a plurality of oblique land regions 13 each defined between a pair of the oblique grooves 10 adjacent to each other in a tire circumferential direction. Each of the oblique land regions 13 is provided with a plurality of joint grooves 15 each connecting between the pair of the oblique grooves 10.

A tread profile is divided into two parts in the axial direction (A) of the tire and has two axially adjacent profile block rows, each of which is formed from profile block elements that are arranged one behind the other over the circumference of the tire and are separated from one another by inclined grooves. The inclined grooves of one profile block row are configured to slope along the axial extent of the inclined grooves through the profile block row, starting from the other profile block row, such that the main direction of extent of the inclined grooves forms an angle of inclination relative to the axial direction (A). The inclined grooves of one profile block row have a direction of inclination which is oriented oppositely to that of the inclined grooves of the other profile block row when seen in the circumferential direction (U).

A tire includes a tread having main grooves linearly continuously extending in tire circumferential direction, and a first land portion formed between the main grooves. 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%.

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 pneumatic tire is provided with a tread, a pair of sidewalls, and a pair of beads. A plurality of bending grooves are provided in an intermediate land located on the inner side of each shoulder main groove. Each of the bending grooves has one end portion opening to the shoulder main groove and the other end closed in the intermediate land. Each of the bending grooves is composed of a first tilting groove portion extending from the opening end portion to the bending portion and a second tilting groove portion extending from the bending portion to the closed end portion. The direction oriented from the opening end portion of the first tilting groove portion toward the bending portion coincides with the rotational direction, and the second tilting groove portion is bent toward the first tilting groove portion with the bending portion serving as an apex.

A motorcycle tire has a unidirectional tread pattern formed by a circumferentially extending center main groove, and main oblique grooves each with a branch groove. The main oblique groove has an axially inner end inside a zero-camber ground contacting width and an axially outer end outside the zero-camber ground contacting width. The axially outer end is positioned in a range between 0% and 20% of the developed half tread width from the tread edge. The branch groove is composed of a first inclined part extending from the main oblique groove at an angle with respect to the tire circumferential direction, and a second inclined part extending at an angle less than the angle . When the developed half tread width is axially equally divided into five portions, the land ratio of each of the five portions is 75% to 85%.
