A method of preparing a tire including the steps of providing a cured tire, the tire including a first bead, a second bead, a carcass layer extending from the first bead to the second bead, and an optional innerliner layer disposed interior to the carcass layer; directly or indirectly applying an air barrier composition to at least a portion of the carcass layer or to at least a portion of the optional innerliner layer to thereby form an air barrier layer; and directly or indirectly applying a dampening member to the air barrier layer.

Pneumatic tire having dampening element adhered to air barrier layer

A motor vehicle tire is disclosed with a pair of post-cure run-flat inserts, each of the pair of post-cure run-flat inserts is disposed within a tire cavity between a shoulder region and a respective upper sidewall region of the tire. The tire further includes a cylindrical sidewall defining an interior cylindrical cavity, each of the cylindrical sidewall and the interior cylindrical cavity extending 360 degrees about a rotational axis of the tire, the cylindrical sidewall having an exterior surface contacting a radially inner surface of an inner liner between the shoulder region and the respective upper sidewall region during a normal inflation condition of the tire.

Post-cure run-flat and/or noise reduction apparatus and method of manufacturing the same

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.

Pneumatic tires with applied air barrier layers

A method of preparing a tire including the steps of: providing a cured tire, the tire including a first bead, a second bead, a carcass layer extending from the first bead to the second bead, and an optional innerliner layer disposed interior to the carcass layer; applying a pair of reinforcing members to the carcass layer or to the optional innerliner layer, if present; and applying an air barrier composition to the pair of reinforcing members, and to a portion of the carcass layer or to a portion of the optional innerliner layer to thereby form an air barrier layer.

Pneumatic tire having reinforcing members and air barrier layer

A tire includes a body ply sheet having a rubber core defined by a top surface having a length and a width, a bottom surface having substantially the same length and width, and side surfaces having a common height. The rubber core is further defined by a top rubber layer and a bottom rubber layer. The body ply sheet includes reinforcement cords disposed between the top rubber layer and the bottom rubber layer. The reinforcement cords are spaced 0.1-4.0 mm apart from each other and span the width of the body ply sheet. Bleeder cords are disposed on the body ply sheet and spaced 8-12 cm apart from each other. Conductive cords are also disposed on the body ply and spaced 20-80 cm apart from each other.

Tire having a conductivity path

A method of manufacturing a tire curing bladder, the method includes the steps of (i) providing a cured tire curing bladder; and (ii) applying an air barrier composition to the cured tire curing bladder to form an air barrier layer. A method of restoring the air retention of a tire curing bladder, the method includes the steps of (i) providing a used tire curing bladder; and (ii) applying an air barrier composition to the used tire curing bladder to form an air barrier layer.
