PROBLEM TO BE SOLVED: To provide a safety tire capable of stable running even in its damaging condition, without sacrificing rolling resistance and comfortableness when the tire is in ordinary running before its damages. SOLUTION: In this safety tire, arranging in an inner side of the tire of hollow doughnut shape a composite material dispersing a closed cell in a continuous phase by a polymer, an internal pressure at 25 deg.C of the cell incorporated in this composite material is 150 kPa or more by the absolute pressure, and an expansion starting temperature of this composite material is set to 80 to 180 deg.C. |
