SAFE TIRE, COMPLEX AND EXPANDABLE COMPOSITION USED FOR IT, AND MANUFACTURING METHOD OF SAFE TIRE

摘要

PROBLEM TO BE SOLVED: To provide a safe tire allowing stable running even in a damaged state of the tire without sacrificing rolling resistance and riding comfortableness in normal running before the damage of the tire. SOLUTION: In this safe tire having a complex having independent air bubble dispersed in a continuous phase made of a polymer body is disposed inside the hollow doughnut like tire, the inner pressure of the independent air bubble built in the complex at 25 deg.C is 150 kPa or higher, and number of kinds of gas filled into the complex is two or more.
