Embodiment Construction

[0086] figure 1 The tire 1 shown comprises a carcass reinforcement composed of layers 2 comprising reinforcing elements of textile type. Layer 2 consists of radially arranged reinforcing elements. The radial positioning of the reinforcing elements is defined by the angle at which said reinforcing elements are laid; a radial arrangement corresponds to said elements being laid at an angle of between 65° and 90° with respect to the longitudinal direction. The ply 2 is composed of two half-plies 2a, 2b forming the circumferential area of ​​the tire 1 in which no carcass reinforcement is present, and axially composed of the ends 9a of each of the half-plies 2a, 2b , 9b defines the boundary.

[0087] Each of the half-plies 2a, 2b is anchored on each side of the tire 1 in a bead 3, the base of which is intended to be mounted on a rim well. Each bead 3 extends radially outwards through a sidewall 4 which meets a tread strip 5 radially outwards. The tire 1 thus constructed has a c...

Abstract

The invention relates to a tyre comprising a carcass-type reinforcing structure (2) and comprising beneath the tread a crown reinforcement structure (6) consisting of at least two reinforcement elements. According to the invention the carcass-type reinforcing structure is produced in two half-layers (2a, 2b) extending from at least the shoulders to the beads and each having an edge beneath the tread, at least the tread surface being composed of: a first polymeric compound (51) extending at least between the edge of each of the half-layers; and at least a second polymeric compound (52) that has physico-chemical properties different from those of said first polymeric compound and covering at least part of each of the half-layers.

Description

technical field [0001] The present invention relates to a tire intended to be fitted to a vehicle, and more particularly to a tire intended to be fitted to a two-wheeled vehicle such as a motorcycle. Background technique [0002] Although not limited to such applications, the invention will be described more particularly with reference to such tires for motorcycles or mopeds. [0003] Reinforcements for tires, especially motorcycle tyres, are commonly - and usually - made from a stack of one or more plies, traditionally referred to as "carcass plies", " Crown ply", etc. This way of naming reinforcements derives from the manufacturing method, which consists in producing a series of semi-finished products in the form of plies with generally longitudinal primary reinforcements, which are then assembled or stacked to form the tire blank. The plies are produced flat and large in size and subsequently cut to fit the dimensions of a given product. The plies are still initially a...
