Document Type and Number:
Japanese Patent JP2009274682
Kind Code:
A
Abstract:

To provide a pneumatic radial tire and a process for producing a retreaded tire capable of improving productivity of the retreaded tire without practically including a buff process of thread rubber.

A pneumatic radial tire which comprises at least one carcass layer which connects right and left bead parts, a belt layer disposed on the outer periphery side of the carcass layer, and a tread disposed on the outer periphery side of the belt layer, wherein the tread has a layered structure comprising a tread-surface-side rubber layer, a belt-layer-side rubber layer, and a thermoplastic film layer interposed therebetween which is constituted of a thermoplastic resin or a thermoplastic elastomer composition obtained by blending a thermoplastic resin with an elastomer. Also provided is a process for producing a retreaded tire from the pneumatic radial tire in which the tread has worn out, the process comprising softening the thermoplastic film layer by heating, separating and removing the tread-surface-side rubber layer to form a tire casing, and then bonding a fresh tread-surface-side rubber layer to the tire casing.
