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 nullTnull with a cylindrical shape with respect to the center axis nullDnull of the tire. The cross section nullTnull extends through the rim 10. When the tire is rolled under a load and a stress is applied on the tire as an arrow nullXnull, a neighboring portion 2d near the end portions 2a, 2b is considerably bending-deformed as arrows nullYnull to absorb the stress. The roundness of the belt layer 8 is thus preserved to reduce the rolling resistance of the tire considerably.
摘要翻译：本发明提供一种充气轮胎和轮辋的组件。轮胎具有至少一个胎体帘布层2和带束层8.帘布层2由帘布层帘线构成并具有端部。带层8由设置在帘布层2的外侧的带束帘线组成。每个带束帘线在与帘布层帘线相交的方向上延伸。每个端部保持在轮辋12中。轮胎的宽度在轮胎的中心轴线“D”的圆周形状的圆周截面“T”中是最大的。横截面“T”延伸穿过轮辋10.当轮胎在负载下滚动并且在轮胎上施加作为箭头“X”的应力时，靠近端部2a，2b的相邻部分2d相当弯曲，变形为箭头“Y”以吸收应力。因此保持带层8的圆度显着降低了轮胎的滚动阻力。

摘要： There is provided a pneumatic tire having an aspect ratio of not less than 60 and considerably improving run flat durability as compared with the conventional type of the run flat tire, wherein at least one cushion rubber layer having a loss tangent lower than a loss tangent (tan null) of a coating rubber for cords of a carcass ply is arranged between an end portion of a belt and a reinforcing rubber layer in a shoulder region and between mutually adjacent tire constitutional members. And also, when the carcass is comprised of plural plies, at least one ply is separated off in a zone beneath the belt, whereby the ride comfort against vibrations can be more improved.
