Problems solved by technology

[0026] In this regard, the applicant has observed that due to the need to configure the tread pattern to provide a tread band with high deformability when running on snow-covered or icy roads, and to provide blocks with sipe Relatively low rigidity of the tread band for snow, winter or studded tires

Embodiment Construction

[0108] refer to figure 1 and 2 , a tire embodied according to the invention is generally indicated at 1 .

[0109] The tire 1 generally comprises a tread band 2 shaped as a torus around the axis of rotation X of the tire 1 , arranged in a radially external position on the belt structure of the tire 1 . Then, in a configuration known per se in the art and not shown in the figures, the belt structure of the tire 1 is coupled to the carcass structure in a radially external position.

[0110] The tread band 2 is made of elastomeric material and is provided with a radially outer tread surface 3 designed so that the tire 1 during its rotation about the axis X comes into contact with the road surface.

[0111] The tire 1 is preferably of the directional type, so that the tire has figure 1 The preferred direction of rotation is shown in F. In this way, a direction of advancement Y tangential to the tread surface 3 and oriented in the direction of rotation F is defined for each poi...

Abstract

A tyre (1) comprising a tread band (2) provided with : - a plurality of central blocks (10a, 10b) disposed in sequence along an equatorial plane (M) defined on the tread band, - a plurality of shoulder blocks (11) extending from opposite axial ends of the tread band (2) towards the equatorial plane, and - a plurality of intermediate blocks (12) disposed in sequence along the circumferential development of the tread band (2) between the central blocks and the shoulder blocks. The plurality of central blocks comprises a plurality of first central blocks (10a) formed by a first branch (15a) and by a second branch (16a) which are substantially rectilinear and extend from a common end in a first direction (A) and a second direction (B) respectively, in order to define a V with its concave portion facing a first axial end (4a) of the tread band, and a plurality of second central blocks (10b) disposed in alternating sequence with the first central blocks and formed by a first branch (15b) and a second branch (16b) which are substantially rectilinear and extend from a common end in the second direction (B) and the first direction (A) respectively, in order to define a V with its concave portion facing a second axial end (4b) of the tread band.

Description

technical field [0001] The present invention relates to tires for wheels, preferably of the studded type, capable of providing a high degree of stability and grip on the various types of road surfaces on which they are driven, whether dry, wet, snow-covered or condensed. icy road. Background technique [0002] The tire generally comprises a carcass structure shaped as a torus around an axis of rotation, on which a belt structure is applied in a radially outer position and further superimposed by a tread band of elastomeric material On said annulus, a tread surface designed to come into contact with the road surface is defined on said elastomeric material. [0003] The tread band is typically intersected by grooves which, together with the blocks which they delimit and define, form the entire tread pattern of the tire, obtained in a very wide range of configurations on the surface of the tread band . [0004] It is known that, since the tread band is the tire component in ...
