摘要： To improve the load supporting capability of a pneumatic safety tire and to prevent the tire bead portion from coming off from the rim seat both during run-flat (flat punctured tire) travel, the pneumatic safety tire comprises a pair of crescent-shaped cross-section reinforcing rubber layers each having the thicknest portion at the tire side portion and a pair of beak-shaped cross-section rim-fixed protruding hard-rubber members each disposed under the reinforcing rubber layer in such a way that annular circumferential bonding surfaces between the two are inclided axially outwardly or inwardly in annular wedge shape. Further, to prevent creases from being produced during green tire forming process and cracks from being produced during run-flat travel in or near the bonding surfaces, crescent-shaped reinforcing layer and the beak-shaped rim-fixed protruding members are extrusion-formed simultaneously before a green tire is formed.

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： To obtain a uniform initial cord tension in an auxiliary layer of a radial tire made up of a toroidal carcass, a belt, the auxiliary layer and a tread rubber, the belt is formed by winding inextensible cords around a drum with a radius of curvature substantially the same as that of a tire tread. Further, when the belt is formed by winding the cords around a flat drum, the auxiliary layer is formed on the belt by winding a heat-shrinkable cord around the belt in spiral fashion in such a way as to apply a higher tension at both the ends of the belt layer than at the center thereof. The radial tire thus manufacture is excellent in high-speed tire durability and tire uniformity, without causing belt separation trouble at high speed.

摘要： A high performance pneumatic radial tire comprises a toroidal carcass, a tread radially outside a crown portion of the carcass, a belt layer interposed between the carcass and the tread and having a same width of the tread, and an auxiliary layer arranged between the belt layer and the tread and covering the entire belt layer. organic cords are buried substantially parallel to an equatorial plane of the tire in the auxiliary layer, and land portions are defined between at least two circumferential main grooves formed in an outer surface portion of the tread and between the circumferential main grooves and axially opposite edges of the tread. In the tire, a rigidity of the tire corresponding to locations overlapping the circumferential main grooves is made smaller than that of portions corresponding to the land portions by, for example, constituting the auxiliary layer from at least two auxiliary plies comprising one auxiliary ply located on a radially innermost side and covering the belt layer over an entire width thereof, and cutting at least a radially outermost auxiliary ply at locations overlapping the circumferential main grooves among the auxiliary plies having portions overlapping the circumferential main groove.

摘要： To improve high-speed durability of the pneumatic tire formed with a directional tread such that transversal grooves are arranged into a herringbone pattern at regular intervals along the tire circumferential direction, the U-shaped cross section of each of the transversal grooves is formed in such a way that a radius (R.sub.1) of curvature of a step-out side corner between a side wall and a bottom of each transversal groove which is first brought into contact with the ground along a tire rotating direction is determined smaller than that (R.sub.2) of a kick-out side corner therebetween which is afterward brought into contact with the ground at a ratio of about 2 to 5.

摘要： When a radial tire is used at high speed (e.g. 250 km/h or more), tire blocks deform outward due to a centrifugal force applied to mass at the center of each block, so that contact pressure rises and therefore the tire is heated into blow out. To overcome this problem, the rubber thickness (gage) of the block partitioned by circumferential grooves and transverse grooves is reduced at the central area of the block. To reduce the rubber thickness, a shallow groove extending along the circumferential groove is formed in the middle of the block or a hole is formed at the center of the block.
摘要翻译：当子午线轮胎以高速（例如250km / h以上）使用时，轮胎块由于施加到每块的中心处的质量的离心力而向外变形，使得接触压力升高，因此轮胎被加热吹熄。为了克服这个问题，在块的中心区域减小了由周向槽和横向槽分隔的块的橡胶厚度（量具）。为了减小橡胶厚度，在块的中间形成有沿着周向槽延伸的浅槽，或者在块的中心形成有孔。
