Retreading and rebuilding of radial tires.

摘要

A method of retreading a radial tire having damaged belt plies, and a curing tube 44 used in retreading the tire. After the tread 22 and damaged belt plies 32 and 34 are removed, a curing tube 44 having a restricting member 46 integral therewith is inserted into the cavity of the tire 10 for limiting expansion of the tire to a predetermined diameter D. The tire 10 is expanded to the predetermined diameter D by inflating the curing tube 44. The tread and belt plies are replaced. The new tread 38 and belt plies 40 and 42 are bonded to the tire 10 while the curing tube 44 is in the cavity of the tire and inflated.
