    摘要: A pneumatic radial ply tire (86, 104) having a tread (106), a carcass (96, 108) with two sidewalls (88a, 88b, 116a, 116b), a radial ply structure (98, 110), and a belt structure (103, 117) located radially between the tread and the radial ply structure. Each sidewall is reinforced with at least one wedge insert (89a, 89b, 118a, 118b, 120a, 120b) which comprises alternating regions (90a, 90b, 122a, 122b) of flexible material and layers (91a, 91b, 124a, 124b) of stiffer material. The layer (91a, 91b, 124a, 124b) of stiffer material constrain the lateral expansion of the wedge insert (89a, 89b, 118a, 118b, 120a, 120b) during runflat operation to provide good riding comfort during normal inflation operation and good sidewall reinforcement during runflat operation.

    摘要: A pneumatic radial ply tire incorporating a crown reinforcing structure comprises at least one reinforcing hoop located approximately on the equatorial plane and disposed radially inward of the tread and radially outward of the carcass structure. The hoop is surrounded or encased by a layer of elastomeric transition material providing a flexible structural connection between the hoop and the adjacent carcass structure and belt structure. The hoop may have a substantially lenticular shape, or a complex shape with two thickened sections or lobes connected by a thin waist-like section, or a shape and a location that is asymmetric with respect to the equatorial plane of the tire, and may be made by winding a thin strip of material such as UHMWPE in an elastomeric matrix. The hoop may replace the belt structure of the tire.

    摘要: A pneumatic radial ply runflat tire 1000 for a vehicle has a tread 1012, a carcass 1022 comprising at least one radial ply 1030 and two sidewalls 1016 each reinforced by a circumferentially disposed crescent-shaped wedge insert. Each insert has an elastomeric porous section 1042 embedded in an elastomeric stiffer layer 1044 of the insert 1040. When the tire is normally inflated, the porous section 1042, and hence the insert as a whole, is flexible, thereby providing comfortable driving characteristics. Under runflat (deflated tire) conditions, the pores in the porous section 1042 collapse, and the porous section 1042 stiffens, and hence the insert as a whole becomes stiff enough to support the load of the vehicle.
