<P>PROBLEM TO BE SOLVED: To provide a safety tire for improving assemblability of rim and fitting reliability after assembling of the rim. <P>SOLUTION: The safe tire comprises a pair of bead parts 3, a pair of side wall parts 4 extending from the bead parts 3 outward in a tire diameter direction, a tread part 5 extending between both of the side wall parts 4, 4. The safety tire is characterized by being equipped with an expansible annular diaphragm 6 which is gripped between the bead parts 3 and the rim 7 in a loading position for loading the tire 1 on the rim 7, and divides a space partitioned between the tire 1 and the rim 7 into two inner/outer chambers in the tire diameter direction. The diaphragm 6 is equipped with at least a communicating part 13 for communicating with the inner chamber 8 and the outer chamber 9. An end part of the tire width direction 10 extends at least up to a bead heel 12 through a bead toe 11 of the bead parts 3. <P>COPYRIGHT: (C)2009,JPO&INPIT |
