Abstract: Tire formed of two halves separated by a median plane, comprising a crown comprising a crown reinforcement comprising a first reinforcing ply (80) and a second reinforcing ply (90) having two axial ends, which is situated radially on the outside of the first reinforcing ply and surmounted by a hooping reinforcement (100) made up of circumferentially orientated reinforcing elements, in which tire the absolute value of the difference D between the distance D1 of the first axial end (92) from the median plane and the distance D2 of the second axial end (93) from the median plane is greater than or equal to 4 mm and less than or equal to 10 mm (4 mm?|D|=|D1?D2|?10 mm).

Abstract: Tire having a load index LI, as defined in the ETRTO Standards Manual 2010, lying in the range between 65 and 105. The tire comprises a tread and an under layer (48) extending over the whole width of the tread and having an average radial height greater than 20% of the average radial height of the tread and a maximum value of tan ? at 23° C. and 10 Hz less than the corresponding value of the tread. Radial carcass reinforcement (60) extends from the beads across the sidewalls as far as the crown. The tire has an outside diameter OD and a nominal section width SW, as defined in the ETRTO Standards Manual 2010, that satisfy the following inequality: OD/SW>?0.00082641 LI2+0.11266 LI?0.185.

Abstract: A tire intended to be mounted on a drop-center rim with a flange height G and a radius of curvature R1 has first and second beads each having an annular reinforcing structure having a radially innermost point, the radial distance between the radially innermost point and the mounting rim being A, and a carcass reinforcement anchored in the two beads by being turned back around the annular reinforcing structure forming, within each bead, a main strand and a turned-back strand, in which the thicknesses EB1 of the first bead and EB2 of the second bead are the distance separating (i) the point on the main strand that is at a distance R from the radially innermost point, where R=G+(R1)/2?A, and (ii) the point on the exterior surface of the bead that is at the distance R from the radially innermost point, and in which |EB1?EB2|?1 mm.

Abstract: A tire intended to be mounted on a drop-center rim with a flange height G and a radius of curvature R1, comprising a first and a second bead, each comprising at least one annular reinforcing structure having a radially innermost point, the radial distance between the radially innermost point and the mounting rim being denoted by A; a carcass reinforcement anchored in the two beads by being turned back around the annular reinforcing structure so as to form, within each bead, a main strand and a turned-back strand, in which the first bead has a thickness EB1 and the second bead has a thickness EB2, the thicknesses EB1 and EB2 defined as the distance separating (i) the point on the main strand that is at a distance R from said point, where R=G+R1/2?A, and (ii) the point on the exterior surface of the bead that is at this same distance R from said point, and in which the absolute value of the difference between the thicknesses EB1 and EB2 is greater than or equal to 1 mm.

Abstract: A tire having a preferential fitting direction to a passenger car, the tire having a carcass reinforcement that extends from one tire bead to the other and, radially outside, a crown reinforcement of width Ls, formed by at least two crown plies, and in addition a meridian reinforcing ply arranged radially between the carcass reinforcement and the crown reinforcement, the meridian reinforcing ply having a width Lr between 15% and 45% Ls of the crown reinforcement, one edge of the reinforcing ply being located a distance D1 from the equatorial plane of the tire between 35% and 50% of Ls, while the other edge is located between the first edge and the equatorial plane of the tire. A method of mounting a group of four such tires on a vehicle.
