Abstract: A passenger tire having a tread, a casing with two sidewalls, one or more radial plies extending from and wrapped about two annular beads and a belt reinforcement structure located radially between the tread and the piles. The tread has a central rib with a first contour-defining curve extending outwards from the mid centerline of the tire towards the sidewalls and a pair of side ribs each having a second contour-defining curve disposed between the central rib and the sidewalls. The first and second contour-defining curves each have first and second radii disposed such that the meeting point of first and second adjacent contour-defining curves cannot contain a single line that is mutually tangential to the first and second adjacent contour-defining curves. First and second circumferential decoupling grooves are disposed on either side of the centerline at the meeting point of the first and second adjacent contour-defining curves, and define a circumferential line at the bottom of the grooves which is a region of greater flexibility than the adjacent ribs of the tire tread to decouple a sidewall bending stresses from the central rib.

Abstract: The present invention provides for an improved device for molding keyhole sipes larger in size, i.e. sipes having a wider passage, than currently being formed in treads that will avoid damaging the tread during formation and removal thereof from a mold. The device includes an elongated deformable body member having a blade extending in a direction away therefrom and substantially along the length thereof. The body member also includes a stiffening member securely fixed in position therein that extends substantially the length thereof. The stiffening member provides a desired rigidity to the deformable body member, thereby limiting flexion along its length under the stress of a rubber formulation when the mold is closed during the molding process. Also, the deformable body member provides low stress on the tread when a slit of the keyhole sipe is pulled around the body member during removal of the tread from a mold.

Abstract: A pneumatic radial ply tire (50) has a tread (52), a carcass (61) with two sidewalls (77, 78), a single radial ply (70) reinforced with inextensible metal cords, two annular beads (36a′, 36b′), and a belt structure (58) located radially between the tread and the radial ply structure (56). Each sidewall (77, 78) is reinforced with wedge inserts (59a, 59b) containing stiffener layers (72a, 72b, 73a, 73b) that carry the compressive loading to which the tire is subjected during runflat operation. The incorporation of wedge-insert stiffeners (72a, 72b, 73a, 73b) provides a light-weight runflat tire having a simplified construction.

Abstract: A pneumatic radial ply tire (50) having a tread (52), a carcass (60) with two sidewalls (77, 78), one or more radial plies (70, 72), two annular beads (36a′, 36b′), a belt structure (56) located radially between the tread and the radial ply structure (58), a fabric underlay (54), deployed radially inward of the belt structure, and a tread insert (66) deployed between the belt structure and the fabric underlay. Said underlay (66) contains circumferentially aligned high-modulus fibers or cords (88) which, in combination with metal belt structure (56) and the tread insert (66), contribute to circumferential tread rigidity. Insert (66), in conjunction with the belt structure (56) and the radial ply structure (58), contributes to lateral tread rigidity. The circumferential and lateral stiffening of the tread (52) enhances high-speed runflat handling and contributes to improved runflat operational life.
