摘要： To improve the durability and the riding comfortableness of a pneumatic safety tire having at least one carcass ply, at least one belt layer, and a pair of crescent-shaped cross-section reinforcing layers, each of the reinforcing layers comprises a higher elastic rubber layer with a hardness of 70 to 85 in Shore A and an elastic modulus of 25 to 60 kg/cm.sup.2 and an anticrack rubber layer with a hardness of 55 to 70 in Shore A and an elastic modulus of 10 to 30 kg/cm.sup.2. The maximum thickness of the reinforcing layer is preferably 4 to 12 mm. Load applied to the tire during run-flat travel is supported mainly by the higher elastic rubber layer, and crack generation due to tire deformation is reduced by the presence of the anticrack rubber layer.

摘要： A method of producing an uncured rubber member by separately producing a rubber composition A of a compounding system excluding a vulcanizing agent and a rubber composition B of a compounding system excluding a vulcanization accelerator and shaping the rubber compositions A and B into given forms through a shaping machine and winding on a rotating support does not cause the scorching at the shaping step and is high in the shaping efficiency. Also, the durability and the internal pressure holding property at a run-flat state are simultaneously established in a tire provided with an innerliner in which a rubber component for the innerliner contains at least 10% by mass of diene rubber in a region corresponding to a tire side portion and a ratio of diene rubber in a region corresponding to a tire tread portion is made lower than that in a side portion corresponding region.
