A non-pneumatic tire includes a shear band having a first membrane layer located radially inward of the outer annular tread, a second membrane layer located radially outward of the first membrane layer, wherein the first and second membrane layer are formed of a plurality of parallel reinforcement cords arranged at an angle of 10 degrees or less with respect to the tire equatorial plane, said outer annular tread further comprises a first angled belt located radially outward of the second membrane layer, and a second angled belt located radially outward of the first angled belt, wherein the first and second angled belt each have parallel reinforcement cords having a belt angle in the range of 15-30 degrees with respect to the tire equatorial plane, and wherein the angle of the second angled belt has an angle equal and opposite direction of the belt angle of the first angled belt.

A method for manufacturing a tire comprising a carcass reinforcement comprising a carcass layer and a working reinforcement comprising a single working layer comprising forming, around a support, a wound carcass assembly (52) intended to form the carcass layer and a wound working assembly intended to form the working layer, and then deforming the support. The wound carcass assembly (52) is formed so as to form either a junction (56) by abutment without forming a superposition, or a junction (56) by overlapping, or without forming a junction.

The present invention is directed to a tire comprising a tread, two sidewalls, a carcass and at least two belts arranged radially between the carcass and the tread in a crown area of the tire. The tread has at least one axially outer edge portion covering the axially outermost edge of at least one of the belts and comprising a different rubber composition than a portion of the tread neighboring the axially outer edge portion of the tread. Furthermore, one of the sidewalls at least partially covers and contacts the axially outer surface of the axially outer edge portion of the tread.

The present invention relates to a vehicle tire comprising a belt bandage, wherein the belt bandage comprises strength members, wherein the strength members comprise hybrid cords arranged parallel to one another within the ply, and wherein the hybrid cords each contain at least one yarn made of polyethylene terephthalate (PET) and at least one yarn made of polyamide.

According to the invention the PET of the yarn of the hybrid cord of the belt bandage is recycled PET (rPET).

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).

Protective reinforcement (3) for a tire has a mean radial thickness T at least equal to two times the diameter D of a −12-reinforce (4), comprises respectively on its radially interior face (31) and on its radially exterior face (32) parts (7) made of elastomeric compound having an axial width W at least equal to the diameter D of a −12-reinforcer (4), and the path of any −12-reinforce (4), in the circumferential direction (XX′), varies radially between the radially interior first face (31) and the radially exterior second face (32), in such a way that the set of paths of the reinforcers (4) of the protective reinforcement (3) constitutes a three-dimensional lattice.
