| 20090194215 | Pneumatic tire with composite bead core - A tire includes a carcass structure including at least one carcass ply, the carcass structure including a crown portion and two axially opposite side portions terminating in beads for mounting the tire on a rim; a tread band; and a belt structure interposed between the carcass structure and the tread band. The bead includes a bead core. The bead core includes: at least one first elongated element including at least one metal wire, and at least one second elongated element including at least one carbon fiber. The bead core results in an increased bead, forcing an improved bead unseating resistance and a decreased weight. | 08-06-2009 |

| 20100051160 | TIRE HAVING A LIGHT WEIGHT BELT STRUCTURE - A tire includes a carcass structure of a substantially toroidal shape, having opposite lateral edges terminating in respective bead structures; a belt structure applied in a radially external position with respect to the carcass structure, the belt structure including at least one belt layer, a tread band radially superimposed on the belt structure; a pair of sidewalls applied laterally on opposite sides with respect to the carcass structure, wherein the at least one belt layer includes at least one reinforcing cod including a core including at least one first elongated element including at least one composite material, the composite material including a plurality of elongated fibers embedded in a polymeric material, the core being wrapped with at least one second elongated element including at least one elementary metal wire. | 03-04-2010 |
| 20100108228 | TIRE HAVING AN IMPROVED BEAD STRUCTURE - A heavy load vehicle tire includes a bead structure having two reinforcing layers adjacent to the inner side of the carcass turned up ply and a chafer layer including reinforcing elements. The reinforcing layers are preferably made of steel cords including preformed filaments, the cords being inclined at angles between +10° to +35° and −10° to −35° with respect to the radial plane of the tire. | 05-06-2010 |
| 20100180999 | Pair Of Pneumatic Tires For Two-Wheeled Vehicles - A pair of tyres comprising a front tyre and a rear tyre to be mounted on a front wheel and a rear wheel respectively of a two-wheeled vehicle, in which each of the front and rear tyres includes: a carcass structure having at least one carcass ply, the ends of which are in engagement with respective circumferential annular reinforcing structures; a belt structure applied to the carcass structure at a radially external position; a tread band applied at a radially external position to said belt structure; a pair of sidewalls laterally applied onto opposite sides relative to said carcass structure; and a pair of reinforcing side structures laterally applied at the sidewalls. Each reinforcing structure includes a plurality of cords where at each point of a cord, an angle different from zero is identified which is included between the tangent of the cord direction at that point and the tangent to a circumferential direction of the tyre passing through the point. The angle is constant or varying in a monotonic manner over the whole length of the cord. | 07-22-2010 |
| 20100269969 | Pneumatic Tyre for vehicle wheels - In a tyre for vehicle wheels, each of the two annular anchoring structures includes at least two annular reinforcing inserts, each of them being made up of at least one first elongated element and at least two reinforcing elements that are mutually spaced apart and each of which extends in a radial direction and includes at least one second elongated element. An end portion of at least one carcass ply lies between two adjacent annular reinforcing inserts. The second elongated element of at least one of the reinforcing elements is of metal material and delimits an angle included between about 20° and about 70° relative to a radial direction passing through a radially internal point thereof. | 10-28-2010 |

| 20090273460 | Pneumatic tyre for vehicle wheels provided with an antenna and method of manufacturing thereof - A pneumatic tyre for vehicle wheels with a radially inner surface of a substantially toroidal conformation, includes at least one antenna provided with an electrically conductive elongated body in engagement with the radially inner surface through a plurality of constraint elements. Each pair of consecutive constraint elements identifies an orthodromic distance smaller than the length of the elongated-body portion between this pair of elements. Also described is a method of setting the antenna on the inner surface of the tyre. | 11-05-2009 |
| 20100289232 | PNEUMATIC TIRE HAVING AN IMPROVED BELT STRUCTURE - A pneumatic tire having a belt structure includes: a first belt layer; a second belt layer in a radially inner position with respect to the first belt layer, a third belt layer in a radially inner position with respect to the first and second belt layers, each belt layer including a plurality of elongated reinforcing elements disposed at a first, second and third belt angle respectively.
