Embodiment Construction

[0034] exist figure 1 In , the tire for motor vehicle wheels according to the present invention is denoted as a whole by 1 and is shown in partial cross-section. exist figure 1 The rest of the tire is not shown in , since the rest of the tire is substantially symmetrically identical to that shown. In particular, the tire 1 is adapted to be mounted on mopeds with a small engine displacement (typically below 300 cc, for example 150 cc).

[0035] In the tire 1, the equatorial plane X-X is defined as a plane orthogonal to the axis of rotation of the tire 1, and the equatorial plane X-X subdivides the tire 1 into two halves.

[0036] The tire 1 comprises a carcass structure 2 comprising at least one carcass ply, which will be described in more detail later.

[0037] The carcass structure 2 is preferably covered on its inner walls with a so-called "liner" comprising a layer of airtight elastic material and adapted to ensure the airtightness of the tire itself when inflated.

Abstract

Motorcycle tyres suited for agile motorcycles having low engine displacement have a tread pattern comprising grooves (21) which extend substantially in transverse direction from one lateral region of the tread band to the other lateral region of the tread band. Other grooves (22) extend substantially in longitudinal direction within a central region (M) of the tread band. Solid portions (23) are also located within the central region of the tread band an alternate with the latter grooves (22) in longitudinal direction.

Description

technical field [0001] The present invention relates to a motorcycle tire, ie a tire having a high transverse curvature in order to provide a sufficient contact surface with the road surface when the motorcycle is leaning to turn. Background technique [0002] Tires for motorcycle wheels should ensure high versatility both in straight lines and in curves. In particular, the tires should always ensure high traction and grip on the road surface, in order to be able to travel on any type of road surface (wet, dry, regular and / or irregular asphalt, etc.) and / Or in any road conditions (urban roads, highways, mountain roads with many curves, etc.) allowing optimal transmission of power and sufficient braking action. [0003] Such tires should also ensure comfort, driving stability, controllability, directionality, road holding, high mileage and normal wear. [0004] The behavior of the tire during running is largely influenced by the number, direction, distribution and shape of...
