摘要： A tire comprises a crown zone comprising a crown reinforcement surmounted radially on the outside by a tread formed from at least one material that is not a conductor of electricity, the crown reinforcement comprising a plurality of layers superposed on one another, each layer of the crown reinforcement comprising two ends in the circumferential direction, these two ends being joined together in an abutment region, the tread comprising a weld region circumferentially offset by an angle of 180 degrees with respect to the region at which the radially outermost layer of the crown reinforcement is superposed. The tire comprises at least one conducting strip positioned between the tread and the crown reinforcement and located circumferentially as to be positioned at equal angular distances between the tread weld region and the region at which the radially outermost reinforcing layer is butted together, these two regions being diametrically opposite.

摘要： The reinforcing structure for a tire is in the form of a stratified assembly formed of two layers of reinforcing strips of completely connected cross section, and flattened in shape. According to the method, the strips of each layer are laid side by side in a main direction of laying. The strips of the first layer are spaced apart by a distance that is less than the width of the strips of the second layer and in such a way that the edges of the strips of the first layer overlap the edges of the strips of the second layer. The two layers of strips are separated by a layer of uncoupling rubber.

摘要： A motorcycle tire includes a tread portion, a pair of sidewall portions, a pair of bead portions, a toroidal carcass extending between the pair of bead portions, and a belt layer and a band layer disposed outwardly in the tire radial direction of the carcass in the tread portion. The carcass includes a plurality of carcass cords. The band layer includes a jointless band ply having a band cord wound spirally at an angle equal to or less than 5 degrees with respect to a tire circumferential direction. The belt layer includes a plurality of belt cords arranged in a direction intersecting with the carcass cords. The belt cords intersect with the carcass cords at an intersection angle θc in a tread crown region, and intersect with the carcass cords at an intersection angle θs in tread shoulder regions, and the intersection angle θc is greater than the intersection angle θs.

The belt layer includes an inner belt ply and an outer belt ply. The band layer includes a band ply arranged between the inner and outer belt plies. The inner belt ply includes belt cords oriented at an angle greater than 5 degrees to the tire circumferential direction and a first development width. The outer belt ply includes belt cords oriented at an angle greater than 5 degrees to the tire circumferential direction and a second development width. The band ply includes band cords oriented at an angle not more than 5 degrees to the tire circumferential direction. The second development width is greater than the first development width.

摘要： A pneumatic tyre includes a tread portion provided with circumferential grooves to form circumferential land portions, a belt layer, and a band layer disposed outwardly in the tyre radial direction of the belt layer. The band layer includes a first layer covering an entire width of the belt layer, and second layers disposed outwardly in the tyre radial direction of the first layer and arranged separately in a tyre axially direction from one another. Each second layer is located radially inwardly of a respective one of the circumferential land portions. In each circumferential land portion, the second layer has at least one axial edge that is away at a distance (A) of equal to or more than 3.0 mm in the tyre axial direction from a groove bottom of one of the circumferential grooves nearest to the at least one axial edge.

摘要： A tire comprises a crown reinforcement comprising: a working reinforcement comprising a single working layer and a hoop reinforcement arranged radially outside the working reinforcement and comprising at least one hooping filamentary reinforcing element (170) wound circumferentially helically so as to extend axially from one axial edge to the other axial edge of the hoop reinforcement. The or each hooping filamentary reinforcing element (170) consists of: two multifilament strands (1701, 1702) of aromatic polyamide or aromatic copolyamide and one multifilament strand (1703) of aliphatic polyamide or of polyester, or three polyester multifilament strands, each multifilament strand (1701, 1702, 1703) being wound in a helix around a main axis (W) common to the three multifilament strands (1701, 1702, 1703). The hoop reinforcement has a tangent modulus at 1.3% elongation ranging from 200 to 650 daN/mm.
