Abstract: A chipper (40, 43, 54) for use in a pneumatic radial ply runflat tire (49) comprises cord reinforcements (42, 42′) making an angle, &agr;′ of between 30° and 50° relative to the circumferential direction. The radially outermost edge (46, 50) of the chipper is located between 10 and 15 millimeters above the wheel rim flange (56) of the wheel-mounted tire and between 5% and 20% of the section height SH of the tire. The chipper is disposed axially inward of the ply turnup end (58). The chipper (40) may comprise a single layer of cords (42), or the chipper (43) may comprise two layers (47, 47′) with the -cords (42, 42′) in the two layers being crossed to form mirror images across a radial reflection axis.

Abstract: A radial ply runflat 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′), and a belt structure (56) located radially between the tread and the radial ply structure (58). The tread has laterally disposed tread ribs (64a,64b) whose contours are defined by circular curves intersecting nontangentially with the circular curve that defines the contour of the central portion of the tread. Each sidewall portion (77,78) has a rib (63a,63b) that is out of contact with the road during normal inflation operation and that engages the road during runflat operation. The tread ribs (64a,64b) are separated from the respective sidewall ribs (63a,63b) by decoupling grooves (65a,65b) which overlie the point of nontangential intersection of the circular curves that define the respective contours of the sidewall ribs and the laterally disposed tread ribs. Decoupling grooves (66a,66b) overlie the point of nontangential intersection of the circular curves that define the respective contours of the laterally disposed tread ribs (64a,64b) and the central portion (54) of the tread.

Abstract: A two-ply radial runflat tire having a belt structure, a ply structure, two inextensible beads and two wedge-insert reinforced sidewalls. The outer ply is reinforced by high-modulus, light-weight aramid. The aramid reinforcement material of the outer ply is clamped around the beads. The outer ply is prestressed in tension during manufacture of the tire. The resultant tire is light in weight and resists upward buckling of the tread during runflat operation.

Abstract: A pneumatic radial ply tire (50) having a tread (52), a carcass (60) with two sidewalls (77, 78), two 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), one or more circumferentially deployed high-modulus incompressible belt reinforcements (66) and/or two or more circumferentially deployed high-modulus tensile-stress-bearing fabric reinforcements (59). Belt reinforcement(s) (66) and/or fabric reinforcement(s) (59) work to increase the lateral and circumferential rigidity of the tread (52) and underlying structures of the carcass (60). The lateral and circumferential stiffening of the tread (52) enhances high-speed runflat handling and contributes to improved runflat operational life.
