PURPOSE:To avoid puncture by a nail or the like and thereby obtain safely running, by cutting a tire tube into plural short pipes and connecting the short pipes in the circumferential direction with their axes directed radially. CONSTITUTION:A tube made of elastic materials such as rubber is cut into plural pipes to connect these pipes in the circumferential direction with their axes directed radially, thus forming a punctureless tire tube. As each of the short pipes is open at the outer end, a nail or the like does not run into the tire tube, and it is possible to avoid puncture as generated in a conventional pneumatic tire. Further, elasticity of each the short pipes may be utilized to secure sufficient comfortability for driving. |
