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.

A tire with a tread reinforcing layer that includes a ply reinforcing structure formed by winding a cord-embedded rubber tape circumferentially of the tire. The ply reinforcing structure includes first oblique segments and second oblique segments which intersect with each other to form a mesh structure having rhombic spaces. The circumferential lengths of the rhombic spaces are less than times the maximum circumferential length of the ground contacting patch of the tire in its normally loaded state.

A tire comprises a tread reinforcing layer comprising a cord-reinforced part formed by winding a rubberized cord strip with at least one reinforcing cord covered with a topping rubber. The cord-reinforced part includes a mesh part in which first inclined segments and second inclined segments of the rubberized cord strip are inclined to opposite directions with respect to the tire circumferential direction. The first inclined segments intersect the second inclined segments, leaving space parts each having a quadrilateral shape. The mesh part has a tire-equator-side first region, a tread-edge-side second region and a third region therebetween, wherein the space parts within the tire-equator-side first region each have an area A1, the space parts within the tread-edge-side second region each have an area A2, and the space parts within the third region each have an area A3 which is smaller than the area A1 and larger than the area A2.

A tire comprises a tread reinforcing layer comprising a cord-reinforced part in which a rubberized cord strip with at least one reinforcing cord covered with a topping rubber is wound. The cord-reinforced part comprises a spiral part in which the rubberized cord strip is wound spirally and circumferentially of the tire. The spiral part includes a first edge part and a second part continued therefrom. In the second part, the rubberized cord strip extends spirally more than one turn around the tread portion. In the first edge part, the rubberized cord strip extends in the tire circumferential direction at an angle smaller than that in the second part, and overlaps the rubberized cord strip in the second part.

Crown reinforcement of an aircraft tire with improved mechanical strength in order to increase the burst pressure of the tire, during a standard pressure test. An aircraft tire comprises a working reinforcement made up of a strip (5) wound continuously in a zigzag, from a starting end (51) to an ending end (52), in a circumferential direction (XX) of the tire, along a periodic curve (7) forming a non-zero angle A with the circumferential direction (XX) of the tire and in an equatorial plane (XZ) of the tire. The starting end (51) and the ending end (52) of the strip (5) are positioned axially at a distance (DI, DF) at most equal to 0.25 times the axial width W.sub.T of the working reinforcement from an axial end (E1, E2) of the working reinforcement.

A cord of a band of a tire has a single-stranded structure in which steel filaments are stranded, and the number of the filaments is not less than three and not greater than six. In a cross-section of the cord, when represents a diameter of a smallest circle that surrounds cross-sections of the filaments, and represents a diameter of each filament, a gap is formed between the filaments such that the diameter is not less than three times the diameter and not greater than six times the diameter in the case of the number of the filaments being three or four. An initial elongation of the cord is not less than 0.1% and not greater than 1.5%.

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=(UcU1)/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.

A pneumatic tire has a tread reinforcing layer comprising a net structure formed from a tape of rubber coated reinforcing cord(s). The net structure comprises first oblique segments and second oblique segments of the tape which intersect with each other, forming interspaces therebetween. The first oblique segment has a first axial outer part in which the angle of the tape with respect to the tire circumferential direction decreases toward one end in the tire axial direction of the net structure. The second oblique segment has a second axial outer part in which the angle of the tape with respect to the tire circumferential direction decreases toward the above-said one end of the net structure. The first axial outside part is connected to the second axial outside part directly or through a circumferential segment of the tape.

A tire is provided with a tire frame member that is made from resin and has a pair of bead portions, a pair of side portions that extend from the bead portions towards an outer side in a tire radial direction, and a crown portion that connects an outer side end in the tire radial direction of one side portion to an outer side end in the tire radial direction of another side portion, and with a crossing belt layer that is provided with plural reinforcing cords that are arranged in rows which are inclined relative to a tire rotation axis of the tire frame member and are coated with a resin material. The crossing belt layer is disposed either directly or via a resin layer on an outer side surface in the tire radial direction of the crown portion.

A method of forming a belt structure for a tire includes providing a drum having a center section. A first drum edge is near a first edge of the center section and a second drum edge is near a second edge of the center section. A first end surface extends from the center section first edge to the drum first edge and a second end surface extends from the center section second edge to the drum second edge, and a radius of each end surface is smaller than the center section radius. A rubber strip reinforced by a plurality of cords includes an outer edge and an inner edge. The strip is wound about the drum, turning from a first winding angle to a second winding angle on an end surface to reduce the tension and length differential between cords at the outer edge and inner edge of the strip.
