| A pneumatic run-flat tire has a bead configuration wherein the axially inner end is radially inward of the axially outer end of the bead. The sidewall of the tire, from the bead region to the upper sidewall is reinforced to form a pillar support in the sidewall. The bead configuration and the pillar reinforcement enable the tire to lock itself onto a tire rim during low pressure operation and be self-supporting. | ||||||

| The innermost carcass ply of a runflat tire (50) having a radial carcass ply is a discontinuous ply (52) that includes two portions (52a,52b) each disposed within one of the sidewalls (43,45). In one embodiment, each of the two discontinuous ply portions is composed of two layers (64,66) of cross-biased cords (65,67) which are disposed between the two wedge inserts (58b,59b) in each sidewall. In another embodiment, the two portions (72a,72b) of the discontinuous ply (72) are composed of wavy metal cords. In a third embodiment, a runflat tire incorporating either embodiment of the discontinuous ply (92a,92b) is built using the locked, tie-in construction for the carcass ply. | ||||||
| 123 | Automobile pneumatic tires including rubber reinforcing plies which take on a supporting function with a deflated tire | US10752403 | 2004-01-06 | US20040140035A1 | 2004-07-22 | Manfred Gerresheim; Karlheinz Baumann; Gunter Dietrich |
| An automobile pneumatic tire comprises a multiple-ply carcass extending in-between two bead rings having allocated bead fillers, a belt arrangement between the plies of the carcass and a tread strip, and rubber reinforcement plies in the sidewall sections assuming a supporting function where the tire is deflated. A first rubber reinforcement ply is inside a first ply of the carcass, a second rubber reinforcement ply is between the first ply of the carcass and the second ply of the carcass, and a third rubber reinforcement ply is between the second ply of the carcass and a third ply of the carcass. The three rubber reinforcement plies extend down with their ends staggered in relation to each other from the bead core area to the edge area of the belt ply. The three rubber plies have different heights in radial direction and different thickness over the height of the sidewall. | ||||||
| 124 | Tire safety system | US10680880 | 2003-10-07 | US20040065398A1 | 2004-04-08 | Itzhak Sapir |
| A tire safety system mounts on a vehicle wheel rim inside a pneumatic tire. A tire air pressure sensor produces a tire air pressure reading mounted inside the tire. An inflatable member forms a toroidal expandable internal safety structure. The inflatable member is mounted against the vehicle wheel rim. The chemicals container inside the inflatable member receives an electrical signal at an activation input. The chemicals container creates pressurized gas inside the inflatable member for inflation when a signal is received at the activation input. A circumferential radially expandable protective belt mounted around the inflatable member expands with inflatable member inflation to accommodate operation the tire when expanded. A computer receiving tire air pressure readings from the tire air pressure sensor sends a signal to the activation input upon a sudden change in tire air pressure. | ||||||
| 125 | Runflat tire construction with ply cords having a variable modulus of elasticity | US09959359 | 2001-10-17 | US06695025B1 | 2004-02-24 | Alain Emile Francois Roesgen; Laurent Colantonio; Marie-Rita Catherine Amelie Thise-Fourgon |
| The tire (70) of the invention incorporates a carcass ply cord material (93) with variable modulus of elasticity to provide an active sidewall structure (82a, 82b). The variable modulus cord material is incorporated in the axially outwardmost ply (90) of a carcass (80) having two plies (88, 90) separated by elastomeric inserts (89a, 89b) in the sidewalls (82a, 82b). The outer ply cord material (93) provides an increased modulus of elasticity with an increase in elongation. The inner ply cords (91) have a modulus that substantially exceeds that of the outer ply cords (93) under normal loads in the inflated mode. Thus, the inner ply (88) dominates the structural response of the sidewalls (82a, 82b) at normal loads in the inflated mode. Under severe sidewall deflection, such as when the tire is uninflated, the outer ply cord (93) is elongated, increasing its modulus of elasticity and thus, shifting the load from the axially inwardmost ply (88) to the axially outwardmost ply (90). | ||||||
| 126 | Cured tire including encapsulated high modulus composite | US09433435 | 1999-11-04 | US06598634B1 | 2003-07-29 | Russell W. Koch; Charles D. Spragg; Edward G. Markow; James M. Kirby |
| A laminate contains a composite, comprising a high melting point thermoplastic such as polyphenylene or epoxy and high modulus fibers such as carbon or graphite, which is encapsulated with a resin. A primer adheres the encapsulated composite to a rubber material such as a tire tread. Alternatively, an undertread layer adheres the tire tread to the primed encapsulated composite. The laminate can be used as a run flat belt in a tire. | ||||||

| 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. | ||||||

| A run-flat tire, i.e., a tire capable of running for a while even when it is flat or uninflated due to a puncture, includes a carcass ply or layer having a turned-up end which reaches one end of a belt layer underlying the tire tread. A crescent-shaped side-reinforcing rubber pad includes a outer-surface-side rubber pad and an inner-surface-side rubber pad arranged which sandwich a fibrous layer therebetween. The inner-surface-side pad, i.e., the one situated inward of the outer-surface-side pad, is thicker than the outer-surface-side pad. The upper end (the end close to the tread) and the lower end (the end close to a bead portion) of the fibrous layer extend slightly beyond the upper and lower ends of the side-reinforcing rubber pad, respectively. | ||||||
| 132 | Front-wheel drive automobile having run-flat tires | US59493 | 1998-04-13 | US6135468A | 2000-10-24 | Frederick A. Lee |
| An automobile having a pair of front wheels and a pair of rear wheels provided with run-flat tires. The front tired wheels which are steerable are driven through a power transmission by an engine housed between these wheels. The tired front wheels are relatively narrow in width to make room for a large engine and are relatively large in diameter to afford a more favorable power transmission ratio and improved steering control. The tired rear-wheels are broad in width and small in diameter to enhance the tire-to-road surface area for more effective braking and to allow for an enlarged trunk capacity. | ||||||

| 135 | Run flat banded pneumatic tire | US782364 | 1997-01-13 | US5879484A | 1999-03-09 | Charles D. Spragg; Edward G. Markow; Thomas W. Bell |
| A run flat pneumatic tire is reinforced by a thin annular composite band imbedded in the crown portion of the tire in combination with a plurality of radial cords or plies in its sidewalls which have freedom in shear with respect to one another. The band is formed by a plurality of layers of material strips wherein each strip is wound in a helical pattern, with adjacent strips being wound at reverse angles to each other. Each layer is formed under sufficient pressure and at an elevated temperature whereby the band is prestressed in tension which decreases the maximum stress at the footprint area of the tire. The invention furthermore incorporates the method of imparting the prestress on the annular band during its manufacture. | ||||||
| 136 | Run-flat tire with an improved bead to rim interface | US872579 | 1997-06-10 | US5868190A | 1999-02-09 | Walter Lee Willard, Jr.; James Milo Endicott; Jeffrey Scott Craddock |
| The run-flat tire has a tread for contacting a ground surface and a belt package with belt plies interior to the tread for support of the tread. A plurality of radially reinforced carcass layers are positioned interior to the belt plies and include at least one carcass layer that extends between spaced apart annular beads. The tire has a pair of sidewalls each extending radially inward from shoulders at lateral edges of the belt package to the annular beads. The sidewalls have a plurality of sidewall stiffening members to support the tire during a loss of inflation pressure. The carcass layers are disposed with the sidewall stiffening members to help support the run-flat tire with a loss of inflation pressure. The spaced apart beads have a unique design including bead cores placed at a predetermined diameter with respect to a rim diameter, dual bead fillers above the bead cores, a heel corner spaced at a radial gap distance from a rim flange and rim interface components having a seat interface distance below the bead core for mounting the run-flat tire on a conventional rim and for sustaining the run-flat tire on the conventional rim with a loss of inflation pressure within the run-flat tire. | ||||||
| 137 | Run-flat tire having partial carcass layers | US691831 | 1996-08-02 | US5795416A | 1998-08-18 | Walter Lee Willard, Jr.; Virginia White Snipes; Allen Eugene Wilson |
| The run-flat tire of this invention includes a pair of bead regions, a crown region with a tread and a tread reinforcing package including a cap ply and self supporting sidewalls between each bead region and the crown region. An innerliner ply maintains air within the inflated tire. The self supporting sidewalls each include a first crescent-shaped reinforcing member, an inner carcass layer, an inner sidewall supporting complex and an outer sidewall and bead protecting complex. The supporting sidewalls effectively have a plurality of crescent-shaped reinforcing members and a plurality of carcass layers. The sidewall supporting complexes are realized by providing first and second partial carcass layers along with a filler rubber portion and a second crescent-shaped reinforcing member, which can be formed by a separate tire building operation. The sidewall protecting complexes can be formed in a similar operation. The run-flat tire of this invention can be realized within standard production rates for building tires.The inflated vs. deflated performance tradeoffs in ride comfort, handling, radial stiffness and endurance of the tire are substantially maintained with improved mass and rolling resistance over previous run-flat tires. This is accomplished with a run-flat tire having relatively small weight increases over a standard tire and with a rim that can be used interchangeably with the standard tire. | ||||||
