A PNEUMATIC TYRE

摘要

A pneumatic tyre formed from a raw cover tyre characterised by a toroidal tyre main body (2) comprising an injection-formed high polymer material having a pair of bead parts (7) width a bead core (19), two sidewall parts (9) extending outwardly in the radial direction of the tyre from said bead part (7) and a tread bottom part (15) disposed between the outer ends of the two sidewall parts (9), a reinforcement layer (6) comprising at least one ply (6a) comprising a reinforcement cord continuously and spirally wound around the outer surface of said tread bottom part (15) in the circumferential direction; and a tread rubber (5) on the outside of the reinforcement layer (6), wherein the reinforcement layer is in a right circular cylindrical form centred on the tye axis in the state where the tyre main body (2) is inflated with standard internal pressure.
