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 post-cure inflation machine for processing a tire may include a tire holder shaft. The tire holder shaft may include a chuck to secure the tire to the tire holder shaft. A hollow passage may be defined in the tire holder shaft. A spray nozzle may be connected to a spray shaft that is telescopically disposed in the hollow passage of the tire holder shaft. The spray nozzle may extend to spray an air barrier material onto the tire.

A method of manufacturing a tire, the method comprising the steps of providing a cured tire subassembly, the subassembly including a first bead and a second bead, a cured carcass layer extending from the first bead to the second bead, and an optional cured innerliner disposed on the carcass layer; and applying an air barrier composition to the cured carcass layer, or to the cured innerliner if present, to form an air barrier layer.

A tire comprises a sealing layer comprising a junction (21) extending in a main direction (D4) forming, with the circumferential direction (Z) of the tire: in a portion (15S) of the sealing layer extending axially in radial line with the working layer, an angle (ES) ranging, in absolute value, from 20? to 60?, and in a portion (15F) of the sealing layer extending radially in each sidewall, an angle (EF), in absolute value, strictly greater than the angle (ES) of the main direction (D4) of the junction (21) in the portion (15S) of the sealing layer extending axially in radial line with the working layer.

In a method for manufacturing a pneumatic tire, molding of a green tire has an assembly step of bonding an inner liner and an unvulcanized rubber sheet with end portions thereof in a width direction being displaced from each other by 50 mm to 500 mm in the width direction to manufacture a laminate, cutting the laminate to have a constant length corresponding to a width of a drum to manufacture a cut sheet, and a joining step of winding the cut sheet on entire circumference of the drum such that a cut surface thereof extends in a circumferential direction of the drum and the inner liner is disposed on an inner surface side, and joining the end portions of the inner liner and joining the end portions of the unvulcanized rubber sheet such that positions of the joined end portions are displaced by a constant distance.

A tire includes a tire frame having an annular shape and containing a resin, and a resin layer that is provided on at least a part of an inner circumferential surface of the tire frame and that contains a urethane resin, the resin layer having a tensile modulus of elasticity of from 2 MPa to 50 MPa, the tensile modulus of elasticity of the resin layer being from 0.01 times to 0.50 times a tensile modulus of elasticity of the tire frame, and the resin layer having a softening point of 80 C. or higher.

An adhesive sealant formulation for tires includes: from 20% to 35% by weight of the total formulation of block copolymers, from 55% to 75% by weight of the total formulation of resins, from 0.2% up to 2.0% by weight of the total formulation of a mixture of stabilizers and antioxidants, where the quantity of stabilizers within the mixture varies from 0 up to a maximum 1.50% by weight of the total formulation and the amount of antioxidants varies from 0 up to a maximum of 1.50% by weight of the total formulation, such as in particular: primary phenolic pentaerythritol-tetrakis(3(3,5-di-tert-butyl-4-hydroxyphenyl)propionate); from a minimum of 5% to a maximum of 35% by weight of the total formulation of paraffinic or naphthenic plasticizers; from a minimum of 2% up to a maximum of 5% by weight of the total formulation of mineral fillers.

A pneumatic tire includes film layers of thermoplastic resin or thermoplastic elastomer composition made by blending an elastomer with the thermoplastic resin, which are superposed by winding the film layer in the circumferential direction of the tire multiple times, a thickness of the film layer is in a range of 0.02 mm to 0.2 mm and a thickness of the rubber layer is in a range of 0.1 mm to 1.2 mm, and the tire wherein a rubber film is interposed between the film layers. The pneumatic tire is produced by preparing a laminated body in which the rubber layer is stuck to at least one surface of the film layer; interposing the rubber layer between the film layers by winding the laminated body in the circumferential direction of the tire multiple times; forming an uncured tire which includes the film layers and the rubber layers; and curing the tire.

A method of manufacturing a film for tire used in an air penetration preventing layer of a pneumatic tire, composed of a thermoplastic elastomer with an elastomer component dispersed within a thermoplastic resin includes performing heat treatment on the film for tire formed by inflation molding or cast molding in a state of being wound in a roll together with a liner material configured to regulate deformation of the film for tire, the heat treatment being at a heat treating temperature equal to or higher than a glass transition temperature of a resin with a highest glass transition temperature in the thermoplastic resin included in the film for tire.

Methods for treating a cured inner liner as well as treated, cured inner liners resulting from such methods are disclosed. Also disclosed are tires containing the treated inner liners. The methods include treatment of the lower surface of inner liner surface with a rubber-containing liquid to produce a rubber-containing film thereupon.
