Document Type and Number:
WIPO Patent Application WO/2012/053226
Kind Code:
A1
Abstract:
Provided is a method for repairing a radial tire, wherein the durability of a patch rubber that is bonded to the damaged portion of a carcass ply from the inner surface side of a tire is enhanced, the service life of the repaired tire is extended, and the time required for repairing is shortened. This method for repairing a radial tire (1) involves a step for bonding a patch rubber (10), in which a plurality of reinforcing elements (11) arranged in parallel is covered with a rubber, to the damaged portion (7) of a carcass ply (5a) from the inner surface side of the tire when at least one ply cord (6a) becomes damaged along with the ply rubber on the carcass ply in a side wall section (3). The method is characterized in that the patch rubber is bonded in a manner such that the reinforcing elements (11) are parallel to one of the tire diameter directions, and in a manner such that at least a portion of each of the plurality of reinforcing elements (11) on the inner side edge (11a, 11b, 11c) of the tire diameter direction is positioned to have a different distance in the perpendicular direction in relation to one of the tire perimeter lines.
