Abstract
The present invention relates to a method of producing a precured retreaded tire, etc., and the purpose of the invention is to produce the tire with saving space and power. Here, a precured retreated tire means a tire made by linking a plate rubber member, which has been vulcanized and molded so as to form tire grooves in advance, to a circumferential surface of a buffed abraded tire without vulcanizing said plate rubber member. A producing method according to the present invention comprises a step to insert a bladder (30) into a tire (T), a step to closely connect a plate of once vulcanized rubber member (T1) to a circumferential face of a buffed tire with an unvulcanized linking rubber (R) placed therebetween by attaching an envelope (48) to an outer circumferential face of the tire with fluid pressure, and a step to vulcanize the linking rubber by a heating device (46) and integrally combine the plate rubber member to the circumferential face of the tire, in order.
