摘要： A side reinforcing rubber layer includes a second rubber portion having a modulus constant between a boundary surface and a bead portion and larger than a first rubber portion arranged on a tread-portion-2 side. The boundary surface intersects outer and inner surfaces of the side reinforcing rubber layer at first and third points, respectively. The first and third points are arranged on the bead-portion side of second and fourth points, respectively, which are closest points to an outer end of a belt layer of the outer and inner surfaces, respectively. A distance between an inner end of the first rubber portion and the second point is larger than a distance between the second point and the first point.

摘要： In producing a side-reinforced type runflat tire in which side reinforcing rubbers with generally crescent-shaped sections are interposed between a carcass and an inner liner, the first drums 11a, 11b on which the side-reinforcing rubbers are to be attached are so configured that their diameter do not substantially fluctuate along the axial direction. The expanding operation of the first drum, the mutually approaching operation of the first drums 11a, 11b and the approaching operation of the bead gripping rings 30A are synchronized. As a result, there is provided a tire and a method of its production capable of being produced by a multi-size mixed flow production system consisting of minimum equipments and of preventing air inclusions and wrinkles between the carcass member 4A and the side-reinforcing rubber 2A.

摘要： A pneumatic tire for a passenger car having a pair of bead portions, a toroidal carcass portion extending over both bead portions, at least two belt layers provided in a crown portion of the carcass, a tread portion positioned at an outer peripheral side of the belt layer, and side wall portions provided at the right and left sides of the tread portion, and which further includes a steel cord as a reinforcing material for reinforcing at least one layer of the carcass portion and the belt layer. The steel cord is formed by plying a plurality of filaments each having a strand diameter of 0.125 to 0.275 mm, and has an inflection point on an S—S curve. A reduction rate of a diameter of the steel cord under a load stress which is one third of breaking strength in comparison with a no load condition is equal to or more than 20%.

摘要： On a building drum, anchoring structures to beads, carcass plies, a belt structure and/or other annular composite components are sequentially assembled with a liner, sidewalls, sidewall inserts, under-belt inserts or other annular elastomer components. Each of the sidewall inserts, sidewalls, or under-belt inserts is made as a one piece construction in a service station operating far away from the building drum for storage on a movable storing device. Actuating members operating on the movable storing device carry the annular elastomer components from the service station to the building drum. A transfer member picks up the annular elastomer components from the movable storing device to transfer them to the building drum.

摘要： A method of forming an air passageway in a an air maintenance tire carcass includes: embedding an elongate strip within a pre-cured flexible tire component of a pre-cured tire carcass, the elongate strip extending in a longitudinal direction between an air inlet cavity and an air outlet cavity in the flexible tire component; curing the pre-cured tire carcass including the flexible tire component; extracting the elongate strip longitudinally end-to-end from occupancy within the flexible tire component; and defining an air passageway in the flexible component by the space previously occupied by the withdrawn elongate strip. A free end portion of the strip is accessible at either the air inlet cavity or the air outlet cavity, and the elongate strip may be extracted from either the air inlet cavity or the air outlet cavity by a tensile withdrawal force applied to the elongate strip free end.

摘要： Reinforcing rubber which constitutes a reinforcing rubber layer in a pneumatic tire 10 is formed by winding a plurality of beltlike reinforcing rubber sheets adapted to have almost the same cross-sectional area and cross-sectional shape around a forming drum over its entire periphery while being shifted in the axial direction of the forming drum such that at least portions thereof in the width direction of the tire overlap each other over the whole periphery of the forming drum and by separately jointing both longitudinal ends of the respective reinforcing rubber sheets. As a result, a pneumatic tire with improved run-flat durability without hindering comfortable riding can be formed while hindrances to manufacture are minimized.
