Tire Carcass Reinforcement For A Two-Wheeled Vehicle

Tire for a two-wheeled motorized vehicle of the motorcycle type, comprising a tread (2), of width L, joined by two sidewalls (3) to two beads (4), said tread comprising first and second elastomer compositions, crown reinforcement (5), radially inside tread (2) comprising a crown layer comprising mutually parallel circumferential reinforcers coated with an elastomer composition and forming a substantially zero angle and at most equal to 5° to the circumferential direction, a carcass reinforcement (6), radially inside crown reinforcement (5), comprising turnup (61) and having thickness M. Carcass reinforcement (61) comprises mutually parallel reinforcers coated with an elastomer composition, and wrapped, in each bead (4), from the inside to the outside of the tire, about bead wire (7) in order to form turnup (8) comprising free end E2. Carcass reinforcement (6) comprises crown portion (611) and lateral portion (612), crown portion (611) extending axially between first and second ends E2, E′2, E2 and E′2 being symmetric to equatorial plane P of the tire, lateral portion (612) extending symmetrically to equatorial plane P radially towards the inside, from radially outermost end E2 to fourth end E4 disposed at the bead wire.
