Abstract: A pneumatic tire includes a carcass reinforced by a carcass ply extending from a first bead to a second bead, at least one belt ply disposed radially outward of the carcass ply in a crown portion of the pneumatic tire, and a bead reinforcement disposed adjacent the first bead and the second bead. The bead reinforcement includes at least one hybrid cord having at least one first core yarn with at least one second aramid wrap yarn wrapped around the first core yarn such that the first core yarn has a modulus less than a modulus of the second wrap yarn.

Abstract: A lubricating system indirectly applies a bladder release agent to a green tire and cures the green tire in a tire curing machine. The system includes a deposition device and a curing bladder. The deposition device directly applies bladder release agent on to a deposition bladder. The deposition bladder is inflated within the green tire in order to deposit the bladder release agent on to an inner surface of the green tire. The curing bladder subsequently receives the green tire with bladder release agent deposited therein and cures the green tire.

Abstract: A pneumatic tire includes a carcass reinforced by a carcass ply, at least one belt ply disposed radially outward of the carcass ply in a crown portion of the pneumatic tire, and at least one overlay ply disposed radially outward of the belt ply in the crown portion of the pneumatic tire. The overlay ply includes at least one hybrid cord having at least one first nylon core yarn with at least one second aramid wrap yarn wrapped around the first core yarn such that the first core yarn has a modulus less than a modulus of the second outer metallic filament.

Abstract: A composite cord includes at least one cellulose-fiber first yarn twisted helically about at least one second yarn. The second yarn includes at least one polyamide, polyester, or PEN. The first yarn has a first LASE and the second yarn has a second LASE. The first LASE is higher than the second LASE at a yarn elongation in a range from 0% to 10%.

Abstract: A pneumatic tire includes a tread, two inextensible annular beads, a carcass ply having two turnup end portions, and an annular cap structure encompassing one of the turnup end portions. Each turnup end portion is wrapped around one of the annular beads. The cap structure has a U-shaped cross-section for surrounding the turnup end portion. The cap structure is constructed of reinforced fabric with fibers oriented in the range from ?45° to +45° with respect to a radial direction of the pneumatic tire.
