Abstract: Provided is a pneumatic tire which has both improved driving stability performance on a dry road surface and improved on-snow performance. A pneumatic tire has defined on the tread first lands and second lands. The first lands and the second lands are provided with recesses. The recesses include first recesses provided in first edges of the first lands, and also include second recesses provided in second edges of the second lands. The second recesses are provided so as not to intersect projection regions formed by projecting the first recesses onto the second edges in the axial direction of the tire.

Abstract: A tire comprises a tread portion 2 comprising a shoulder main groove 5 extending on a side of a tread edge Te and comprising inner and outer groove walls 11 and 12. The inner groove wall 11 has an angle ?1 with respect to a tread normal line in a cross section of the shoulder main groove 5 periodically increasing and decreasing in a tire circumferential direction so as to comprise concave and convex wall portions 16 and 17 arranged alternately in the tire circumferential direction. The outer groove wall 12 has an angle ?2 with respect to a tread normal line in the cross section periodically increasing and decreasing in the tire circumferential direction so as to comprise convex and concave wall portions 22 and 21 arranged alternately in the tire circumferential direction. The angle ?2 is larger than the angle ?1 in any cross section of the groove.

The concave wall portions 16 are provided at inner end portions thereof in a tire axial direction with recess portions 20 locally recessed inwardly in the tire axial direction and having openings at a ground contacting surface of the tread portion 2.

Abstract: A tire includes a tread part having main grooves each continuously extending in a tire circumferential direction, and land portions demarcated by the main grooves. The tread part has a tread surface, each of the land portions has slots formed such that each of the slots is recessed from the tread surface and extending from a first end to a second end in a curve forming an arc shape, and each of the slots has an opening edge on the tread surface such that the opening edge is forming a crescent shape that is gradually increased in width from the first end and the second end toward a longitudinal direction central portion of each of the slots.

Abstract: A pneumatic tire includes a tread portion provided with a circumferentially and continuously extending zigzag shoulder main groove located adjacent to a tread edge, a shoulder lateral groove extending axially outwardly from the shoulder main groove and a central lateral groove extending axially inwardly from the shoulder main groove. The shoulder main groove includes an inner corner portion protruding axially inwardly. The central lateral groove includes a first groove portion, a second groove portion and a confluence portion at which the first groove portion and the second groove portion meet. The confluence portion of the central lateral groove is communicated with the inner corner portion of the shoulder main groove. The shoulder lateral groove is located so that an extended portion in which the shoulder lateral groove is extended axially inwardly overlaps with the confluence portion at least partially.

Abstract: A tread portion of a pneumatic tire includes inner land portions between outer circumferential main grooves disposed most on tread ground-contact end sides and at least one inner circumferential main groove on the inner side thereof. The inner land portions are divided into inner blocks by inner lateral grooves inclined at an angle ? of 10 to 40°. The inner lateral grooves consist of first inner lateral grooves and second inner lateral grooves which are alternately arranged in a circumferential direction. The first inner lateral grooves include a wide-width part connecting to the outer circumferential main groove and a narrow-width part connecting to the inner circumferential main groove.
