PURPOSE:To put a tire in soft adhesion to the broad width in traveling at the time of puncture so as to reduce its damage by forming a double tire through providing a built-in tire and filling it with air. CONSTITUTION:An oval projection part is formed inside a wheel 1 in the oval shape a little more projecting than an outer wheel 14. Then a built-in tire 4 is arranged with a tire, the inside of which is formed by soft rubber 3, and both tires are filled with air to form a double tire. Thus, a serious accident at the time of puncture can be prevented. |
