摘要： The present invention relates to a tire designed to be fitted on the driving axles of a motor vehicle for medium or heavy load. This tire is provided with a tread comprising a plurality of full-depth transverse grooves and four circumferential series of inclined grooves and four circumferential series of inclined incisions which delimit five circumferential rows of blocks, namely two axially outer rows, two intermediate rows, and one central row lying essentially across the equatorial plane.Each transverse groove extends across the whole width of the tread, and consists of a central portion, located between a pair of consecutive blocks of the central row, and a pair of lateral portions, located between pairs of consecutive blocks of the intermediate and shoulder rows.The two lateral portions of each transverse groove are staggered circumferentially with respect to each other and penetrate into the body of the central row of blocks. The central portion of the transverse groove has a depth of 3 mm, while the depth of the incisions located between the shoulder blocks and the intermediate blocks is less than the depth of the inclined incisions located between the intermediate blocks and the central blocks.

摘要： A tire capable of reducing a resistance to a fluid in a groove to improve the wet performances. By forming smaller grooves (or riblets 20) having a depth set within a range of 0.01 to 0.5 mm at a pitch within a range of 0.01 to 0.5 mm in the walls of a circumferential groove and a transverse groove, more specifically, the resistance to the water flowing in the groove is reduced to improve the drainage efficiency of the groove. By arranging a turbulence generating zone having a number of pointed projections at the groove side faces at the confluence between the circumferential groove and the transverse groove, on the other hand, there is suppressed the separation of the water flow in the vicinity of the confluence. With these constructions, it is possible to improve the wet performances of the tire better than the prior art.

摘要： A pneumatic tire having two main grooves in the tread that are provided symmetrically with the equatorial plane of the pneumatic tire and which extend in the circumferential direction of the pneumatic tire. The tread is divided into a central portion formed between the main grooves and shoulder portions formed outward of the main grooves in the direction of tire's width. Each of the central and shoulder portions is provided with a plurality of lateral grooves that extend in the direction of tire's width. The lateral grooves in the central portion and those in each shoulder portion are inclined in opposite directions with respect to the axial direction of the tire. All walls of the central lateral grooves are inclined in the same direction with respect to a line in the radial direction of the tire. All walls of the shoulder lateral grooves are inclined in opposite directions to the walls of the central lateral grooves with respect to a line in the radial direction of the pneumatic tire.

摘要： A tire having a decreased percentage of void and superior wear abilities, yet still having improved wet traction ability is disclosed. The improved wet traction ability is enhanced by the flow isolating characteristic of the minor grooves of the tire. By reducing the amount of water flow between the major and minor grooves for a prescribed period during which the major grooves evacuate water away from the tire, there is a reduction in the volume and nature of turbulence due to the intersecting water flows exiting the minor grooves into the major grooves. This reduction of turbulence allows for fluid to be properly channeled away from the contact patch area by their major grooves.
