Abstract
There is a tire capable of stably running even if the tire is subjected to external injury without sacrificing rolling resistance and ride comfort in the usual running before being subjected to external injury, wherein a composite body consisting of a continuous phase of a resin and closed cells is arranged in an inside of a hollow doughnut-shaped tire and the composite body has a cell content of 80.00 vol % to 98.75 vol % and an internal pressure at 25° C. in the closed cell included therein is not less than 150 kPa as an absolute pressure.
