Abstract
The invention provides an assembly of a pneumatic tire and a rim. The tire has at least one carcass plyand a belt layer. The plyis composed of ply cords and has end portions. The belt layeris composed of belt cords provided outside of the ply. Each belt cord extends in a direction intersecting the ply cord. Each of the end portions is held in the rim. 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. When the tire is rolled under a load and a stress is applied on the tire as an arrow “X”, a neighboring portionnear the end portionsis considerably bending-deformed as arrows “Y” to absorb the stress. The roundness of the belt layeris thus preserved to reduce the rolling resistance of the tire considerably.
