Abstract
A tire comprising at least two working layers and at least one layer of reinforcing elements. The layer of circumferential reinforcing elements comprises at least a central part and two axially exterior parts, the extent to which the circumferential reinforcing elements of the central part are penetrated by the rubber compound with which they are coated being less than the extent to which the circumferential reinforcing elements of the axially exterior parts are penetrated by the rubber compound with which they are coated.
Claims22
A tire with a radial carcass reinforcement, comprising:
- a crown reinforcement formed of at least two working crown layers of inextensible reinforcing elements, crossed from one of said working crown layers to another of said working crown layers making angles of between 10° and 45′ with the circumferential direction, said crown reinforcement being radially capped by a tread that is connected to two beads via two sidewalls, said crown reinforcement further comprising at least one layer of circumferential reinforcing elements,
- wherein said at least one layer of circumferential reinforcing elements comprises at least one central part between two axially exterior parts,
- wherein, via temperature control during vulcanization, the extent to which the circumferential reinforcing elements of said at least one central part are penetrated by a rubber compound with which they are coated is less than the extent to which the circumferential reinforcing elements of the axially exterior parts are penetrated by a rubber compound with which they are coated, and
- wherein the circumferential reinforcing elements in said at least one central part and said two axially exterior parts are formed from the same metal cord.
