    摘要： A pneumatic tire (10), which has, in the surface of the tread (11), lug grooves (15) on one side extending from one axial edge towards the axial center of the tire in such a manner as to intersect with the circumferential direction of the tire and lug grooves (15) on the other side extending in a symmetrically opposite direction from the axial center towards the other axial edge of the tire, has at least one circumferential groove (12) extending circumferentially around the tire. Also, circumferential grooves (12, 13a, 13b) are so formed as to satisfy a relationship of "1 ≦ (S/L) ≦ 3" where L is the axial length of the central region, which is the region enclosed by two straight parallel lines each passing through the center between the contact width center (CL) and the contact edge with the shoulder regions being the regions axially outside of the parallel lines, and S is the total of the groove areas of the circumferential grooves (12, 13a, 13b) disposed in the central region. Therefore, the pneumatic tire (10) not only secures the steering stability performance on wet road surfaces, but also improves the steering stability and wear resistance performance on dry road surfaces.

    摘要： The pneumatic tire (1) includes lateral communication grooves (3, 3a, 3b), and circumferential grooves (4). In a tread portion shoulder region, the lateral communication groove (3a) is disposed between a pair of V-shaped crossing grooves (2a, 2b) adjacent in a tire circumferential direction and extends from a tread edge portion toward a tire equatorial plane (CL). In a tread portion center region, the lateral communication groove (3a) communicates with the V-shaped crossing groove (2b) located to a projecting side of the V-shape of the pair of V-shaped crossing grooves (2a, 2b) and does not communicate with the other V-shaped crossing groove (2a) of the pair. The circumferential grooves (4) are disposed in the tread portion shoulder region and extend in the tire circumferential direction, communicating with the V-shaped crossing grooves (2) and the lateral communication grooves (3).

    摘要： A pneumatic tire, for which noises of passage are decreased while draining performance being maintained on a directional tread pattern, and a pneumatic tire set. Arranged on a tread surface, for which a direction of tire revolution is indicated, alternately in a circumferential direction of a tire are groups of rightwardly inclined grooves, each group composed of a unit of grooves starting at a tread center portion and inclining in a direction opposite to the direction of tire revolution to pass through a rightward shoulder edge, and groups of leftwardly inclined grooves, each group composed of a unit of grooves starting at the tread center portion and inclining in the direction opposite to the direction of tire revolution to pass through a leftward shoulder edge. Formed on the tread center portion are a single, main rib, which is defined zigzaggedly in a circumferential direction of the tire by starting ends of the groups of rightwardly inclined grooves and the groups of leftwardly inclined grooves, and sub-ribs branching off the main rib along the groups of rightwardly inclined grooves and the groups of leftwardly inclined grooves. Further, noises are decreased by lessening a groove area ratio for a tire for rear wheels, and providing small grooves at variable pitches on the sub-ribs of a tire for idler wheels.

    摘要： A tire is disclosed having a tread extending from a first tread edge to a second tread edge and having a plurality of blocks defining a plurality of lateral grooves. The lateral grooves have a groove bottom defining a radial groove depth. A first biting side extends outwardly from the groove bottom to a first biting edge, and a first non-biting side extending outwardly from the groove bottom to a first non-biting edge. At least one peak is disposed in at least one of the lateral grooves. The peak extends outwardly from the groove bottom and terminates radially at an outer end and axially at a distance from the equatorial plane less than or equal to one half of the tread width. The peak has a height between 25 percent and 75 percent of the depth of its lateral groove. Multiple peaks may be disposed within a groove.
