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 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： A high-speed running pneumatic radial tire comprises a cylindrical crown portion, a pair of sidewall portions extending inward therefrom, a radial carcass extending from one of the sidewall portions through the crown portion to the other sidewall portion, and a belt and a tread successively superimposed on the crown portion outward in the radial direction of the tire. The tread has plural rows of blocks defined by plural circumferential grooves and many lateral grooves, and the belt is comprised of at least two main crosscord belt layers and an auxiliary belt layer arranged thereon. The auxiliary belt layer is formed by spirally winding a rubberized ribbon ply of heat-shrinkable cords on the main belt layers, in which an overlapped amount of the ribbon ply is made large in a zone of the tread substantially corresponding to the block row than in a zone of the tread substantially corresponding to the circumferential groove.

摘要： A low profile pneumatic radial tire comprises at least one carcass ply containing cords arranged substantially at 90.degree. relative to a circumference of a tread, and a belt consisting of at least two belt layers which are composed of metal cords inclined relative to the circumference of the tread and intersected with one another between the adjacent belt layers and which are arranged upon a crown of the carcass. The tread surrounds the crown, and is provided with a pair of circumferential main grooves which are disposed symmetrically with respect to an equatorial plane of the tire and which divide a treading portion of the tread into a central region and axially opposite side regions and which are separated by a distance ranging from 45 to 65% of a maximum width of the tire in the state that the tire is assembled onto a normal rim and inflated at a normal internal pressure. The width of the belt ranges from 110 to 130% of a distance between intersections of an imaginary straight line which tangentially contracts with a top surface of a wear indicator projecting from a bottom of each of the circumferential grooves and which is drawn in parallel with a tire rotary axis and a tire contour line at axially opposite side regions of the tread, and the thickness of a tread rubber at maximum width edges of the tread ranges from 30 to 80% of that at the intersections.

摘要： To improve high-speed durability of a low-section pneumatic radial tire without producing tire separation at both belt ends and expansion at both tread sidewalls after the tire has been worn off to some extent, the tire belt structure disposed between the tire tread and the carcass is composed of two belt layers and a plurality of auxiliary layers. The auxiliary layers comprises a first auxiliary layer extending over the belt layers and at least second and third auxiliary layers arranged on both axially outside end of the tread in such a way that an axially outer end of each of the auxiliary layers extends to near the tread sidewall and an axially inner end of each of the auxiliary layers extends to or beyond under at least an axially outermost circumferential groove formed on the tread in step fashion extending from tread center to tread end or vice versa. Further, these auxiliary layers are formed by winding a ribbon including at least two heat-shrinkable fiber cords coated with a coating rubber in spiral fashion on the circumferential surface of the belt layers.

摘要： A pneumatic radial tire comprises a tread provided with a plurality of circumferential grooves extending in a circumferential direction of the tire, and plural rows of land portions defined between axially adjacent circumferential grooves and between each of edges of the tread and the adjacent main circumferential groove. That groove wall of at least the circumferential groove located nearest to at least one of the tread edges on a treading surface of the tread which is positioned on a side of the one of the tread edges is inclined to gradually increase a width of the groove toward the surface of the tread from a location spaced by 10-70% of a depth of the circumferential groove radially outwardly from a bottom thereof. The width of an opening of the circumferential groove to the surface of the tread is in a range of 3-18 mm.
