Abstract

PURPOSE: To decrease the change of the diameter of a tire, caused by the generation of heat, by a method wherein a pressure easing layer is arranged, as well as urethane elastic body is placed in a cavity of a tire, which is formed by a wheel rim and the shell of tire.
CONSTITUTION: The pressure easing layer 4 is arranged to the part adjacent to a rim 2, as well as the shell of a tire is put fixedly on a wheel rim 2. The inner tube 5 is arranged, adjacent to the inside of a part, encircled by a pressure easing layer 4 and the shell of a tire 3, and urethane elastic body 6 is filled inside the inner tube 5. The pressure easing layer 4 made of rubber foam body is arranged in order to ease the rise of inner pressure of a tire due to the thermal expansion of urethane elastic body while a wheel is running.
