PURPOSE:To provide a radial tire that can improve the qualities of heating and reinforcement and at the same time realize a light weight and a low fuel cost. CONSTITUTION:A radial tire is constituted such that a rubber composition that is prepared by mixing 20-70 pts.wt of carbon black whose nitrogen adsorption ratio surface area(N2SA) is 60-84m<2>/g and whose DBP suction oil quantity is 120-200ml and whose ratio of the nitrogen absorption ratio surface area(N2SA) to an iodine adsorption quantity(IA), N2SA/IA, is 1.10 or more, with 100 pts.wt. of raw material rubber consisting of one kind or two kinds or more of diene rubber, is used for at least three kinds or more of members where the rubber composition accounts for 5vol.% out of the whole volume of the tire, out of the respective members contituting the tire excepting a tire reinforcement material. |
