Kind Code:
A
Abstract:
PURPOSE:To enable excellent cushioning performance to be secured even at the time of rupturing of a tyre in the tyre whose annular hollow portion formed with a rubber tyre and a rim is charged with an elastic support member which supports the rubber tyre by using hollow fiber for the elastic support member. CONSTITUTION:In a tyre with a rubber tyre 3 installed in the rim 4 of a wheel, an annular hollow portion 5 which is formed with the rubber tyre 3 and the rim 4 is charged with cut fiber hollow fiber 6 as an elastic support member. For example, polyethylene terephthalate system fiber whose diameter D is 1mm and bore is 0.5mm is used for this hollow fiber 6, and it is cut so that the length L is 100mm, namely, the ratio of L/D becomes 100. The annular hollow portion 5 is charged with the hollow fiber 6 by the method of oscillation, the method of decompression or the method of both combination, and its bulk density is set to be, for example, 0.05g/cm<3>.
