摘要： A radial ply, passenger vehicle tire has a tread with a substantially flat tread profile, a belt structure, and a carcass comprising two sidewalls, two beads and one or more plies. The one or more plies have a loaded shoulder ply radius that is smaller than the tire's unloaded shoulder ply radius. This design eliminates tread-lift and eliminates the need for decoupling grooves in the shoulder regions of the tread.

摘要： A heavy duty radial tire which is provided with traverse grooves extending between the tread edges and longitudinal grooves extending between the traverse grooves so as to form shoulder blocks arranged along each of the tread edges and inner blocks each disposed on the axially inside of one of the shoulder blocks. The longitudinal grooves between the shoulder blocks and the inner blocks have a depth Wga of 0.7 to 1.0 times the depth Dy of the traverse grooves, and the longitudinal grooves are each inclined at an acute angle with respect to the circumferential direction to have an axial extent range Y whose axial width W1 is in a range of from 1.0 to 10.0 times the depth Wga. In a cross section of the tire under a normally inflated unloaded condition, the tread profile is made up of a center profile Si and a shoulder profile So. The shoulder profile So extends continuously from each of the axial ends of the center profile Si through an inflection point P to one of the tread edges. The center profile Si is a circular arc of a radius Rc having the center on the tire equatorial plane, and the shoulder profile So is a substantially straight line or alternatively an arc having less curvature than the center profile Si. The inflection point P is located within the axial extent range Y of the longitudinal grooves.

摘要： A tyre for a vehicle wheel includes a carcass structure, a belt structure associated coaxially with the carcass structure, and a tread band extending coaxially around the belt structure. The tread band includes a relief pattern including at least one row of blocks separated by transverse grooves intersecting two circumferential grooves. Each block of the at least one row is essentially delimited by two longitudinal sides in a circumferential direction of the tyre and two transverse sides with respect to a predetermined rolling direction of the tyre. Each block of the at least one row is formed by two axially-adjacent block portions. The transverse sides of each block portion include at least two successive curvilinear portions shaped differently from each other. The transverse grooves include two branches, each branch including a widened cross-section of substantially-curvilinear shape disposed in an area substantially equidistant from ends of a respective branch.

摘要： A pneumatic tire which comprises a tread portion with a pair of tread edges, and a tire shoulder extending radially inwardly from one of the tread edges, provided with a curved surface comprising a convex curve, wherein, on a cylindrical surface centered on the tire axis and intersecting the curved surface, the convex curve swells axially outwards and has a curvature, and the curvature gradually diminishes towards the radially inside from the tread edge. It is possible that the tread portion is provided along the tread edges with a circumferentially extending rib and/or a circumferential row of blocks. In case of circumferential rib, the rib is provided with the curved surface comprising a plurality of the convex curves and a plurality of convex curves alternating therewith so that the curved surface is waved in the tire circumferential direction. In case of blocks in a circumferential row, it is preferable that each block is provided with the curved surface comprising at last one convex curve.
