The non-contact region does not contact the road surface in the normal road state, and when a length of the non-contact region is W1 and a length of the main body land portion both along the tire width direction is Rw, 0.2RwW10.5Rw.

A tread pattern of a pneumatic tire includes two outer circumferential main grooves and two inner circumferential main grooves. Each of the two inner circumferential main grooves comprises a first groove wall and a second groove wall facing the first groove wall. The first groove walls include first oblique wall elements that extend obliquely outward in a tire width direction and second oblique wall elements that extend obliquely inward in the tire width direction and extend for a shorter length than the first oblique wall elements. The second groove walls include third oblique wall elements that extend obliquely inward in the tire width direction and fourth oblique wall elements that extend obliquely outward in the tire width direction and extend for a shorter length than the third oblique wall elements.

A pneumatic tire in which a tread part is provided with a pair of central main grooves extending continuously around the circumference of the tire on both sides of a tire equator C, and central thin grooves extending continuously around the circumference of the tire on the tire-axially inner sides of the central main grooves and having less groove width than the central main grooves. The central thin grooves include a linear first central thin groove running along the tire circumference, and zigzagging second central thin grooves. The first central thin groove is provided on the tire-axially inner sides of the second central thin grooves.

An outer side rib 46 is formed at a side relative to the plural circumference direction main grooves that is at the vehicle outer side when the tire is mounted at a vehicle. A land portion of the outer side rib 46 is continuous in the tire circumference direction. Of the plural circumference direction main grooves, an outermost side circumference direction main groove 24 is formed at the vehicle outermost side when the tire is mounted. Fourth lug grooves 42 extend from the outermost side circumference direction main groove 24 toward the outer side rib 46. The groove width of each fourth lug groove 42 widens from the outermost side circumference direction main groove 24 side toward the outer side rib 46 side. The fourth lug grooves 42 terminate at the outermost side circumference direction main groove 24 side relative to a tire ground contact edge 16E.

To provide a pneumatic tire which is improved in on-snow performance, while maintaining steering stability on dry road surface. The pneumatic tire is provided in a tread portion 2 with a pair of shoulder main grooves 3, a center main groove 4, shoulder land portions 6, and middle land portions 5. The middle land portions 5 are provided with middle lateral grooves 10 extending from the shoulder main grooves 3 toward the inside in the tire axial direction, while gradually decreasing the angle with respect to tire circumferential direction. The middle lateral groove 10 is provided with a groove bottom sipe 15 opened in the groove bottom.

A vehicle tire (1), comprising a tread (2) which is intended for rolling contact against a surface, said tread (2) being formed with a tread pattern (20) which comprises circumferential grooves (25) and transverse grooves (26) for removing water from a contact patch between the surface and the tire (1). The transverse groove (26) increases in width when progressing in a longitudinal direction of the transverse groove (26) from a sidewall (41, 42) of the tire (1) towards a center line (CL) of the tire and when progressing in a radial direction (R) outward from a base (263) of the transverse groove.

A tread portion of a pneumatic tire includes a pair of first main grooves extending in a tire circumferential direction formed at a position on either outer side in the tire lateral direction of a first land portion including a tire equatorial plane; a pair of second main grooves extending in the tire circumferential direction formed at a position outward from the first main grooves in the tire lateral direction; and first lug grooves formed in a second land portion between the first main grooves and the second main grooves, the first lug grooves opening to one of the first main grooves at one end and opening to one of the second main grooves at an other end. The first lug grooves have a groove width of 2 mm or greater and have the same inclination direction in the tire lateral direction with respect to the tire circumferential direction.

A pneumatic tire includes first main grooves formed on outer sides, in the lateral direction, of a first land including an equatorial plane and extending in the circumferential direction; second main grooves outside, in the lateral direction, of the first main grooves and extending in the circumferential direction; auxiliary grooves formed on second lands between the first main grooves and the second main grooves, opening to the second main grooves, and terminating in the second lands; and first sipes inclined identically to the auxiliary grooves and crossing the second lands. The auxiliary grooves are formed into a shape bending at a bend point, and include a first portion extending from an opening end to the bend point, and a second portion extending from the bend point to a terminating end. A groove width of the first portion gradually reduces from the opening end to the bend point.

A pneumatic tire includes first and second circumferential grooves, an intermediate land portion, wedge portions, intermediate land portion lug grooves, and a circumferential narrow groove. The circumferential grooves are provided in a tread surface. The intermediate land portion is formed between the circumferential grooves. The wedge portions are provided in the tire circumferential direction at the second circumferential groove and incline in the tire circumferential direction. The intermediate land portion lug grooves are provided with ends in communication with the circumferential grooves and divide the intermediate land portion into block portions in the tire circumferential direction. The circumferential narrow groove is configured with ends in communication with intermediate land portion lug grooves that are adjacent, divides each of the block portions between the intermediate land portion lug grooves, and has a groove width that increases and decreases between the intermediate land portion lug grooves that are adjacent.

A pneumatic tire includes inner land portions, formed between a center main groove and outer main grooves on both sides of the center main groove, which are divided into blocks by sub-grooves. A pair of the sub-grooves positioned on both sides of the center main groove is inclined in the same direction with respect to the tire width direction, disposed such that openings on the center main groove side overlap in the tire circumferential direction, and the circumferential components of the sub-grooves are continuous throughout the tire circumference. A groove width of the sub-grooves changes at a middle portion in the length direction such that the sub-grooves include a narrow width section positioned on the outer main groove side and have a groove width W1 that is relatively small, and a wide section positioned on the center main groove side and having a groove width W2 that is relatively large.
