摘要： The invention relates to a tyre (1) for a two-wheeled vehicle, comprising a tread surface (2) comprising studs (3) made from an elastomeric material, the studs (3) extending radially from a bottom surface (4), at least one stud (3) comprising a first portion (31) with height hi extending radially between the bottom surface (4) and a second portion with height h
2 , the first portion (31) comprising a radially outer face (311) with surface S1 and the second portion (32) comprising a radially inner face (321) with surface S2, the radially outer face (311) of the first portion (31) and the radially inner face (321) of the second portion (32) having non-coinciding respective outer contours and being in contact with each other by a contact surface S12. The aim of the inventors was to design tread surface studs for a tyre for a two-wheeled vehicle for which a manual cutting operation is easy, quick and reproducible. According to the invention, this aim was achieved by a contact surface S12 between the radially outer face (311) of the first potion (31) and the radially inner face (321) of the second portion (32) at most equal to 0.6 times the surface S1 of the radially outer face (311) of the first portion (31).

摘要： The invention relates to a tire tread for a two-wheel vehicle, which improves the rolling grip on an operating surface capable of becoming slippery, said tread including units (1, 2, 3) separated from each other by grooves (4), each unit including a contact surface (10, 20, 30) intended to come into contact with the operating surface when the tire is rolling, and side surfaces intersecting the contact surface in order to form edges defining a contour of the contact surface having a geometric shape with at least three branches, each branch (11, 21, 31) ending in a point (110, 210, 310) the angle of which is equal to at least 20 degrees and, at most, equal to 90 degrees, the branches (11, 21, 31) of each unit (1, 2, 3), taken in twos, defining recessed portions (1, 2, 3) therebetween, each unit (1, 2, 3) being provided with slots (111, 112, 113; 211, 212, 213; 311, 312, 313) terminating, at one of the ends thereof, in one of the recesses formed on the surface of the unit, and at a single point at the other end thereof, so as to create basic patterns including at least two points of the contact surface, said basic patterns of a single unit making contact with each other as the contact surface passes over the operating surface. Furthermore, in at least one portion of the tread, the orientations of the units (1, 2, 3) are angularly offset relative to each other based on the axial position thereof relative to the equatorial mid-plane.
