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： A pneumatic radial ply tire for heavier load conditions having a reduced weight, high durability bead area. The pneumatic tire includes a tire bead and a carcass ply folded about the bead to define a main body portion and a turnup portion. The turnup portion is folded around the bead and located adjacent the main body portion radially outward of the bead. The turnup portion has a turnup height of approximately 35-45% of the total section height. A thin rubber strip associated with the bead is disposed between the main body portion and the turnup portion and has an insert height of approximately 25% of the total section height. The pneumatic tire further includes a chafer having a maximum chafer gauge of not more than approximately 1.5 times the thickness of the tire side wall.

摘要： The invention provides an assembly of a pneumatic tire and a rim. The tire has at least one carcass ply 2 and a belt layer 8. The ply 2 is composed of ply cords and has end portions. The belt layer 8 is composed of belt cords provided outside of the ply 2. Each belt cord extends in a direction intersecting the ply cord. Each of the end portions is held in the rim 12. The width of the tire is maximum in a circumferential cross section “T” with a cylindrical shape with respect to the center axis “D” of the tire. The cross section “T” extends through the rim 10. When the tire is rolled under a load and a stress is applied on the tire as an arrow “X”, a neighboring portion 2d near the end portions 2a, 2b is considerably bending-deformed as arrows “Y” to absorb the stress. The roundness of the belt layer 8 is thus preserved to reduce the rolling resistance of the tire considerably.
