Abstract: Tire comprising at least one working layer (41). The radially outermost one thereof comprises at least one undulation (412) radially on the outside of the points of the working layer (41) that are in line with the centre of the bottom face (243) of the major groove (24) closest to undulation (412). The undulation (412) of the radially outermost working layer (41) is such that, over at least 10% of the radially outer surface (ROS) of the said working layer (41), the radial distance (do) between the radially outer surface (ROS) and the tread surface (21) is at least 1 mm less than the radial distance (dc) between the radially outer surface (ROS) and the tread surface (21), which is the distance in line with the centre of the bottom face (243) of the major groove (24) closest to the said undulation (412).

Abstract: The reinforcing element (34) has a cross-section with a flattened overall shape having an aspect ratio greater than or equal to 5 and extending in a main direction (Z1). It comprises a lateral edge (46) made of a polymeric composition comprising a thermoplastic polymer, the lateral edge (46) extending in a general direction substantially parallel to the main direction. The reinforcing element (34) is such that R=(Uc−U1)/Uc>11%, where Uc is the average value of the microhardness of the reinforcing element (34) measured in its central part, and U1 is the average value of the microhardness of the reinforcing element (34) measured at its lateral edge (36). The lateral edge (46) does not have any ridges.

Abstract: Belted pneumatic tires characterized by improved treadreinforcing breaker constructions are disclosed. In any such breaker, a single-section plural-layer non-metallic textile cord ply structure having the cords thereof oriented at a 0* angle to the median equatorial plane of the tire is combined with a plural-layer ply structure of metallic wires or strips which in each layer are crossed relative to those in the other layer and are oriented at a substantial bias angle, preferably between about 18* and 75*, to the said plane. The plural-layer textile cord ply structure, which may be located radially outwardly or inwardly of the metal ply structure or between the layers thereof, is constituted by a single length of breaker cord fabric wound in a continuous spiral circumferentially of the carcass for at least a plurality of full turns and is considerably narrower than the metal ply structure. Such tires are found to be possessed of good road-holding or cornering ability while affording good riding comfort. This abstract is not to be taken either as a complete exposition or as a limitation of the present invention, however, the full nature and extent of the invention being discernible only by reference to and from the entire disclosure.

Abstract: 1,047,777. Pneumatic tyres. COMPAGNIE GENERALE DES ESTABLISSMENTS MICHELIN RAISON SOCIALE " MICHELIN ET CIE ". Aug. 12, 1963 [Sept. 3, 1962], No. 31764/63. Heading B7C. A pneumatic tyre is provided with a tread reinforcement extending over substantially the whole axial width of the tread and imparting to the tread a transverse rigidity which differs on opposite sides of the midcircumferential plane of the tyre. The reinforcement may comprise a number of superimposed plies of parallel cords. The number of plies may differ on opposite sides A 1 B 1 , B 1 C 1 of the midcircumferential plane X-X to provide the difference in transverse rigidity. Alternatively, the cords in the region A 1 B 1 may be of rayon while those in the region B 1 C 1 may be steel cables; or the angle made with the midcircumferential plane X-X by the cords of each ply may be larger in the region A 1 B 1 than in the region B 1 C 1 , thus providing the greater rigidity in the region B 1 C 1 . In a further embodiment, Fig. 7, a single ply of an elastomer tapers in radial thickness across the axial width of the tread to give greater rigidity in the region A 1 B 1 .
