PURPOSE:To prevent a puncture by interposing an assistant liquefied lubricant between the support outer surface of a tube, to which a rivet bar with a collar is fitted, and the outer surface of a collar section. CONSTITUTION:A large number of through-holes 2 reaching an inner circumferential surface from the grounding surface of the tire 1 are drilled at proper intervals in the circumferential direction of the grounding surface of the tire. The rivet bar 3 with the collar is fitted into the through-hole 2 under the state in which a nose is projected slightly from the grounding surface of the tire, and the collar section 4 is supported to the tube 5 in the tire 1. The assistant liquefied lubricant 7 is interposed between the support outer surface of the tube 5 and the outer surface of the collar section 4, friction between both the support outer surface and the outer surface of the collar section is relaxed at all times while the liquid film fills the role of a protective film for the internal tube 5, and the tire is slid and moved smoothly even against sudden shocks in rugged roads. |
