AI Technical Summary

Problems solved by technology

For example, a chamfer that is wide enough and deep enough can lead to an excessive reduction in the size of the block surface that is in contact with the road surface as well as to a decrease in the rigidity of the block, thereby reducing its resistance to tangential stresses

Embodiment Construction

[0126] First refer to Figure 1 to Figure 4 , the reference numeral 1 in its entirety designates a tire for vehicle wheels formed in accordance with the present invention.

[0127] The tire 1 has a conventional substantially toroidal shape extending around the axis of rotation so as to define an axial direction Y of the tire which intersects the equatorial plane X perpendicular to the axis of rotation.

[0128] The tire 1 comprises a tread band 2 on which a tread surface 3 is defined, which tread surface is located on the radially outer part of the tread band 2 and is intended to be in contact with the road surface.

[0129] The tire 1 is preferably intended for installation on high performance automobiles and has, for example, a nominal cross-sectional width of about 225 mm and a rim diameter of 17 inches.

[0130] On the tread band 2 is defined a central area 4 extending circumferentially and symmetrically around the equatorial plane X and a pair of shoulder areas 5 which a...

Abstract

A tire (1) for a vehicle wheel comprising a tread band (2) on which a radially outer tread surface (3) is defined and a plurality of blocks (10, 10a; 100; 200; 300) of recesses (9; 9a); each block comprises a tread surface portion (11) and a first side wall (12) extending at least partially from the bottom of one of said recesses ( 13) extends towards the tread surface portion and at least a section thereof is connected to the tread surface portion (11) by a connecting surface (15) having an at least partially curvilinear profile; the connecting surface (15) is joined to the first side along a contact line wall, at which line of contact the tangential plane of the first side wall and the tangential plane of the connecting surface form an acute angle (α) greater than 20° such that between the connecting surface (15) and the first side wall (12) Corners are defined; moreover, the connecting surface (15) is joined to the tread surface portion (11) along a line of contact in a substantially tangential manner.

Description

technical field [0001] The present invention relates to tires for vehicle wheels, in particular for high-performance automobiles. Background technique [0002] Tyres generally comprise a carcass structure shaped as a toroid about an axis of rotation and having at least one carcass ply with engagement in corresponding annular anchoring structures, ie the beads the end flaps. [0003] At a radially outer position of the carcass structure there is provided a belt structure which, in the case of tires for automobiles, comprises at least two belts radially superimposed by a rubber-coated fabric made, the rubber-coated fabric is provided with reinforcing cords (usually metal cords) arranged in each belt parallel to each other and crosswise with respect to the reinforcing cords of adjacent belts, The reinforcing cords are preferably symmetrical with respect to the equatorial plane of the tire. [0004] The belt structure preferably further comprises a third layer of fabric or me...
