Abstract

PURPOSE: To improve safety factor and durability as a result of getting good adhesion, by adhering stepped tread piece which is provided with one or more stepped projections in fringe of lower edge part, onto the base tyre and vulcanize, mediated by unvalcanized cushion rubber.
CONSTITUTION: Using reformed tread piece 2B which is provided with stepped projection 9, at least one stair, at its lower edge fringe, type to be reclaimed is processed. At the time of production, cover tyre with elastic cover 12 and put air exhausting fibre material 13 for discharge air etc. which exist between cover 12 and tread piece 2B, between tyre surface and cover 12 and furthermore, insert air bag 14 inside of basic tyre 1 and then give air pressure on outside of tyre and guide into air bag 14 higher air pressure than outer air pressure, heat up and vulcanize. By this let flow-run unvulcanized cushion rubber 3 and let encroach angle part of stepped projection 9 go into back face of cover 12 and as well fill up rubber 3 till grooved cavity 16 of buff face 4 of base tyre 1.
