Embodiment Construction

[0089] Referring to the above-mentioned figures, the device according to the invention for tires of vehicles is generally designated by the numeral 1 .

[0090] The tire 1 mainly comprises a carcass structure 2 having at least one carcass ply 3 joined to the carcass ply 3 by two annular anchoring structures 4 integrated into what are now called "beads" 5 In this area, the tire 1 is usually joined to the corresponding mounting rim at the bead 5 .

[0091] The belt structure 6 is attached and wound on one or more carcass plies 3 along the circumferential direction, and the tread strip 7 is laminated on the belt structure 6 along the circumferential direction.

[0092] Sidewalls 8 are attached to two opposite side portions of the carcass ply 3 , both sidewalls extending from the corresponding bead 5 to the corresponding sidewall of the tread strip 7 .

[0093] The tire 1 is specially designed for high performance and ultra high performance vehicles, it is also suitable for sport...

Abstract

The tread band (7) of a tyre (1) has two circumferential portions, a central one (13) and an inner intermediate one (14) respectively, that are subdivided into centre (20) and intermediate (24) blocksrespectively; an inner-shoulder circumferential portion (16) has first (26) and second (27) inner-shoulder cuts, axially offset from each other and distributed in an alternated sequence, to confine acontinuous inner-shoulder rest surface (29) with an undulated course; an outer intermediate circumferential portion (15) has first (34) and second (35) intermediate cuts, and an outer-shoulder circumferential portion (17) has first (30) and second (31) outer-shoulder cuts. The first and second intermediate cuts (34, 35) and the outer-shoulder cuts (30, 31) respectively, mutually converge at an angle of about 20 DEG and are axially offset from each other and circumferentially distributed in an alternated sequence, to delimit continuous rest surfaces, an intermediate (36) and outer-shoulder (33) surface respectively, with an undulated course.

Description

technical field [0001] The invention relates to a tire for vehicles. More specifically, the invention is applicable to high-performance and ultra-high-performance passenger cars and racing vehicles, especially road racing cars with high handling characteristics. Background technique [0002] For this type of tire, it is usually required to have the best characteristics in terms of traction power and braking grip performance, and it is required to have handling on both dry and slippery road surfaces, and can meet the requirements of wear resistance . [0003] Existing tires for vehicles have a tread structure on which blocks are provided consisting of circumferential grooves extending substantially in the longitudinal direction and transverse grooves extending substantially in the axial direction. Made of limits. The blocks formed by interlacing said grooves have several different shapes, suitably designed and arranged in circumferentially side-by-side rows, each of which ...
