Tire assembling method and refitting apparatus for use in refit of tire assembly

摘要

A refitting apparatus for a tire assembly "w" having a disk wheel "a" having engaging rims and a tire "d" fitted to the disk wheel and having tire bead rims and side walls. The apparatus is constituted to perform a refit process in which a pressing step of bringing one of the tire bead rims "e" of the tire into pressing contact with one of the engaging rims "b" of the disk wheel "a" by supplying air into the tire "d" and a releasing step of releasing the one of tire bead rims "e" of the tire "d" from the one of engaging rims "b" of the disk wheel "a" are repeated a predetermined number of times for each of the tire bead rims "e". Since the tire bead rims "e" are repeatedly brought into pressing contact with the engaging rims "b" and released therefrom, the tire bead rims "e" snugly fit with the engaging rims "b", so that the RFV value is considerably lowered and stable maneuverability during driving can be obtained unless the fitting state is subsequently changed.
