The pneumatic tire according to the present embodiment includes a shoulder land portion that is formed between a ground contact end and the shoulder main groove, a central land portion that is formed on the other side of the shoulder main groove in the tire width direction, a plurality of first inclined grooves that are provided in the central land portion at intervals in the tire circumferential direction, and a plurality of second inclined grooves that are provided in the shoulder land portion at intervals in the tire circumferential direction. The first inclined groove of which one end is open to the shoulder main groove and the other end terminates in the central land portion extends in a direction inclined with respect to the tire circumferential direction, and the second inclined groove is open to the shoulder main groove and provided on an extension of the first inclined groove.

A pneumatic tire includes a tread portion being provided with at least one circumferentially and continuously extending main groove and at least one land portion adjacent to the main groove. The land portion includes a corner portion formed between a ground contact surface and a sidewall of the land portion on the side of the main groove. The land portion is provided with a lug groove extending from the main groove and terminating within the land portion. The corner portion includes a chamfered portion and a non-chamfered portion. The chamfered portion includes a first end in communication with the lug groove.

A tyre for winter comprises a tread portion 2 having a first tread edge (Te1) and a second tread edge (Te2) and sipes 40 provided in at least a part of the tread portion 2. The tread portion 2 is provided with a plurality of first oblique grooves (10A) each extending obliquely from the first tread edge (Te1) toward the second tread edge (Te2). Each of the first oblique grooves (10A) has an inner end (10a) terminating between a tyre equator (C) and the second tread edge (Te2). The inner end (10a) is not connected with other grooves.

A pneumatic tire comprises a tread portion provided with tread grooves defining a asymmetrical tread pattern. The tread grooves include an outboard shoulder main groove and an outboard crown main groove extending zigzag continuously in the tire circumferential direction. The outboard shoulder main groove is composed of alternate long groove segments and short groove segments which are inclined with respect to the tire circumferential direction to the outboard tread edge. The inclination angle b of the short groove segments is larger than The inclination angle a of the long groove segments. The groove widths of the long groove segments are gradually increased toward the outboard tread edge.

A heavy duty pneumatic tire includes a tread including a pair of central portions, a pair of middle portions and a pair of shoulder portions, wherein each of the portions has an axial width varying periodically while increasing and decreasing in a circumferential direction of the tire. Each of the central portions includes a central block with a hexagonal shaped top face and a central sipe. A total that is the sum of each maximum axial width of the central portions, each maximum axial width of the middle portions, each maximum axial width of the shoulder portions, a maximum axial length of the central sipe provided on one of the central portions, and a maximum axial length of the central sipe provided on the other one of the central portions is in a range of from 1.05 to 1.31 times a tread width.

A motorcycle tire includes a tread portion provided with inclined main grooves arranged between the tire equator and a first tread edge and sub-grooves smaller than the inclined main grooves in groove width. The inclined main grooves include inner main grooves each extending from a first end located on the tire equator side to a second end located on the first tread edge side with an inclination with respect to a tire circumferential direction, wherein no other grooves are provided between the first end of each inner main groove and the tire equator. The sub-grooves include first sub-grooves extending from the inner main grooves toward the tire equator with an opposite inclination direction to the inner main grooves with respect to the tire circumferential direction and terminating on the tire equator side without being communicated with any other grooves.

A tire includes a tread surface portion with inclined grooves, 2ND longitudinal grooves, and shoulder longitudinal grooves; and an indicator portion that indicates a rotation direction of the tire in which a vehicle travels forward. The inclined groove gradually extends forward in the rotation direction toward a tire equator from the outside in the tire width direction. A front surface among inner surfaces defining the inclined groove includes a first side surface with an inner end portion to which the 2ND longitudinal groove is open, a second side surface positioned closer to an inside than the first side surface and of which an outer end portion is positioned closer to a rear side than the inner end portion of the first side surface, and a stepped surface that connects an inner edge of the first side surface to an outer edge of the second side surface and faces the outside.

Performance on snowy roads is improved. Provided is a pneumatic tire, of which the mounting orientation on a vehicle is indicated. An outer middle land part is formed between a first major groove and a second major groove. The first major groove has first portions and second portions alternately formed in the tire circumferential direction, the second portions being wider than the first portions. The outer middle land part is provided with a plurality of middle inclined grooves not directly interconnected with either the first major groove or the second major groove, a plurality of outer middle lug grooves connecting the second portions of the first major groove and the middle inclined grooves, and inner middle lug grooves connecting the middle inclined grooves and the second major groove. The outer middle lug grooves are provided to different positions in the tire circumferential direction than the inner middle lug grooves.

A tire includes an outboard tread edge and an inboard tread edge to be located on an outboard side and an inboard side of a vehicle, respectively, circumferentially and continuously extending main grooves, and land portions divided by the main grooves. The land portions include an outboard shoulder land portion, an outboard middle land portion, an inboard shoulder land portion, and an inboard middle land portion. Each of the outboard shoulder land portion, the inboard shoulder land portion, and the inboard middle land portion is provided with axially extending lateral grooves. The outboard middle land portion is provided with outboard middle lateral grooves extending from an edge of the outboard middle land portion on the outboard tread edge side toward the inboard tread edge. The outboard middle lateral grooves are inclined with respect to a tire circumferential direction at angles smaller than those of the lateral grooves.
