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 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 pneumatic tire includes a single carcass ply and at least one belt ply disposed radially outward of the carcass ply in a crown portion of the pneumatic tire. The carcass ply includes only one type of composite cord. The cord consists of one single aramid first yarn twisted helically about one single polyester second yarn. The first yarn and the second yarn have a different moduli of elasticity. The first yarn has a modulus greater than the modulus of the second yarn.

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 carcass having at least one reinforced ply, a tread disposed radially outward of the carcass, and a belt structure disposed radially between the carcass and the tread. The belt structure includes a single woven layer of crimped metallic cords extending in the radial direction and in the circumferential direction.

Abstract: A pneumatic tire includes a carcass, two sidewalls spaced apart a distance, two beads, a tread disposed radially outward of a crown of the carcass, and an overlay radially interposed between the tread and the carcass. The overlay has UT steel reinforcing cords. The cords have filaments with diameters ranging from 0.08 mm to 0.60 mm.

Abstract: A pneumatic tire for a vehicle includes a carcass reinforced by a carcass ply. The pneumatic further includes at least one belt ply disposed radially outward of the carcass ply in a crown portion of the pneumatic tire. The belt ply includes at least one composite cord having at least one first yarn and at least one second metallic filament wrapped together such that the first yarn has a modulus less than a modulus of the second metallic filament.

Abstract: The present invention is directed towards a pneumatic radial tire. The tire is comprised of a reinforcing belt structure wherein the belt plies are divided into at least three segments. The reinforcing cords in each segment of a ply are oriented in the same inclination direction. By maintaining the same cord inclination in the segments, dividing the belt ply into segments creates hinge points for the belt ply, reducing the stiffness of the ply across the width of the tread from the centerline of the tire to the tread edges. If the belt structure has more than one reinforcing ply, the segments of the adjacent plies are staggered by a distance at greater than the radial height between the radially inner side of the adjacent belt plies.

Abstract: A pneumatic radial tire includes at least two belt plies reinforced with steel monofilaments inclined at an angle of 10.degree. to 30.degree. with respect to the equatorial plane of the tire, the monofilaments being laid at an end count ranging from 25 to 60 ends per inch and having a diameter of from 0.25 to 0.40 mm, a tensile strength of at least 4080 MPa-(2000.times.D).times.95 percent where D is the filament diameter in millimeters and a fatigue resistance of at least 3500 cycles as measured by the three-roll bending fatigue test. Preferably, the filament diameter ranges from 0.30 to 0.35 mm, the tensile strength of each monofilament is at least 4400 MPa-(2000.times.D).times.95 percent and the fatigue resistance ranges from 3500 to 6000 cycles.
