摘要： A pneumatic tire has a carcass structure extending through a pair of opposing bead portions and an inner liner located inward of the carcass structure, each bead portion comprising a bead core about which is wrapped the carcass structure and a toeguard. Each bead portion has a bead toe, a bead base, and a bead heel, the bead base extending between the bead toe and the bead heel. The bead heel has a profile corresponding to a sector of an ellipse or approximates a sector of an ellipse by having a dual radius structure. The bead base may have a dual taper configuration. The bead core may be substantially centered in the bead portion, as determined by the material thickness at three locations about the bead core.

摘要： An expandable, toroidal shaped bladder for use in a tire curing press has a pair of opposing annular beads and an expansion portion location between the pair of annular beads. The expansion portion of the bladder has a central portion, shoulder portions, and sidewall portions. When the bladder is in a mounted but uninflated mode, the shoulder portions of the bladder have a radius of curvature R1 significantly less than a radius of curvature Rc of the central portion. The shoulder portions have a bubble or square-like configuration.

摘要： The method of designing a bead flange profile (24) for a pneumatic tire (30) to be mounted on a design rim (40) as specified for the tire size has the steps of (a) selecting a design rim and a cured tire construction and bead profile (33); (b) predicting or measuring the tire deformation upon mounting and inflation; (c) analyzing the deformation to show the compressed beat seat profile (23) and the bead flange profile (24) contacting the rim flange; (d) identifying any gaps between the tire (30) and the rim (40); (e) modifying the tire's bead flange profile (24) to eliminate any gaps by moving selected points on the bead flange profile (24) in proportion to the local gap sizes; (f) shifting all modified points axially inward by a distance so that the molded base width remains the same as the original profile (24); and then (g) smoothing the connections between the modified portion and the rest of the bead profile (33).
