摘要： A tread is provided with at least one rubber stud of orientation XX′ perpendicular or inclined with respect to the tread surface. The rubber stud has a side wall bounded by at least one incision and an outer end wall. The stud is joined to the tread at its base (the rubber stud part located farthest inward on the tread) and by at least one rubber connecting element joining the side wall of said stud to the rest of the tread. The projected length, on the tread surface in new condition and in the direction XX′, of the principal geometrical lines of the surfaces of intersection of all the connecting elements of each rubber stud, represents at least 80 percent of the contour perimeter, measured on the same surface, of each rubber stud. Preferably, the principal geometrical lines bounding the surfaces of intersection of the connecting elements are in the form of helixes around XX′, and the projected length of said lines is equal or close to 100 percent of the perimeter.

摘要： A tire tread band for medium/heavy duty motor-vehicles having circumferential grooves confining three pairs of respectively center, intermediate and shoulder ribs. Respective tread blocks are defined along the center and intermediate ribs and they are confined by transverse cuts. The center cuts impart a cusp-shaped end conformation and a hollow-shaped end conformation to the respective blocks, and the shapes of said end portions mutually match. The intermediate cuts run in the linear extension of the center cuts to give the respective blocks a rhomboidal configuration. The tire can be alternately associated with a driving axle or a driven axle, by merely reversing its direction of rotation, so that the following results are selectively achieved: an increase in the traction capability by the intermediate blocks or an increase in the directional capability as a result of the mutual wedging between the center blocks at the ground-contacting area.

摘要： A pneumatic tire comprises a plurality of main grooves in a tread of a tire. The main grooves substantially circumferentially extend and are spaced apart from each other in an axial direction of the tire. Each the main grooves is continuous. Intersection angles between an equatorial plane of the tire and tangents to each the main grooves are larger from a starting end to a terminal end of the main groove opening at a tread end of the tire. The pneumatic tire further comprises a plurality of sipes in a tread of the tire. The sipes extend substantially in axial directions of the tire but are inclined relative to the equatorial plane of the tire and spaced apart from each other in circumferential directions. Each the sipe is inclined with its opening directing forward in a rotating direction of the tire.

摘要： Taking a groove side-wall to a position at ½ a groove depth from a tread face of lug groove as a tread-in side first inclined portion, and taking a groove side-wall from the position at ½ groove depth to a groove bottom as a tread-in side second inclined portion, then the following A1 is set less than the following B1. When viewed in cross-section orthogonal to a length direction of the lug groove: A1 is an area of a region enclosed by an imaginary line passing through an end portion on a tread face side of the tread-in side first inclined portion and perpendicular to the tread face, by an imaginary line passing through an end portion on a groove bottom side of the tread-in side first inclined portion and orthogonal to the imaginary line, and by the tread-in side first inclined portion; and B1 is an area of a region enclosed by an imaginary line passing through an end portion on a tread face side of the tread-in side second inclined portion and perpendicular to the tread face, by an imaginary line passing through the deepest portion of the lug groove and parallel to the tread face, and by the tread-in side second inclined portion.

摘要： A tire is provided having a tread region that includes continuous ribs which extend diagonally across the transverse direction of the tire. Partial sipes are provided at the trailing edges of the ribs. Full sipes can also be provided with the partial sipes. The ribs may form various patterns such as e.g., an S-shaped pattern, chevron pattern, and others. The tire provides improved traction performance over non-diagonal ribs while still providing desirable rolling resistance performance and control of irregular wear.

摘要： A pneumatic tire is molded by using a vulcanizing mold in which blades 20, each composed of a metal thin plate having an inclined portion 20a in the depth direction and a plurality of through holes 20G with the same sectional form as that of projections to be formed in the sipe in the inclined portion 20a are buried in a groove portion corresponding to the tire block of the vulcanizing mold, thereby forming 3D sipes having unevenness in the radial direction of the block and a plurality of pairs of projections in the inclined portion in the block of the tire. Thereby, when longitudinal force is applied to the tire, adjacent small blocks of the block come into close contact with each other only at the positions of the projections of the 3D sipes, thereby making it possible to ensure the block stiffness of the pneumatic tire 10 without reducing the drainage function.
