Problems solved by technology

From an energetic point of view, the results are desirable, but the lack of rubber compound corresponding to the location of the groove reduces the area of ​​the tire in contact with the ground in the contact footprint and thus limits the transmitted forces, especially during acceleration in the case of the front wheels or in the case of the rear wheels)

Embodiment Construction

[0076] figure 1 Depicted is a partial perspective view of a tire 1 intended to be mounted to the front wheel of a two-wheeled motorcycle, and more particularly showing the outer surface 2 of its tread. The curvature value of tire 1 exceeds 0.15, preferably exceeds 0.3. This value of curvature is defined by the Ht / Wt ratio, which means the ratio of the height of the tread to the maximum width of the tire tread.

[0077] In a manner not depicted in the figures, tire 1 comprises a carcass reinforcement composed of layers comprising reinforcing elements of textile type. This layer consists of radially arranged reinforcing elements. The radial positioning of the reinforcing elements is defined by the angle at which said reinforcing elements are arranged; a radial arrangement corresponds to said elements being arranged at an angle between 65° and 90° relative to the longitudinal direction of the tyre.

[0078] Said carcass reinforcement is anchored on each side of the tire 1 in ...

Abstract

The invention relates to a tire for a two-wheeled motor vehicle, said tire comprising a tread, wherein at least the central portion of the tread comprises at least one circumferentially continuous groove (5), said groove being formed along at least 80% of the length thereof by at least one sipe and along at most 20% of the length thereof by at least one portion (6) having a width larger than that of a sipe, and the exposed surface of said at least one sipe is greater than the exposed surface of said at least one portion having a width larger than that of a sipe.

Description

technical field [0001] The present invention relates to tires intended to be mounted to vehicles, and more particularly to two-wheeled vehicles, such as motorcycles, and also more particularly to two-wheeled vehicles having speeds above W For motorcycle tires, the W corresponds to a speed of 270 km / h. Background technique [0002] Although not limited to such applications, the invention will be described more particularly with reference to such tires for motorcycles or motorcycles. [0003] Like all other tyres, motorcycle tires have evolved towards radial tyres, the structure of which consists of a carcass reinforcement made of one or two layers of reinforcing elements forming an angle with the circumferential direction It may be between 65° and 90°, a crown reinforcement made of reinforcing elements radially overlying the top of said carcass reinforcement. However, some non-radial tires do exist, and the present invention also relates to these non-radial tires. The inve...
