    摘要: The present invention relates to a radial ply tire (230) with a tread (232) subdivided transversely into a central portion (250) having central ribs (260a,260b), shoulder portions (254a, 254b) having shoulder ribs (270a,270b) and intermediate portions (252a, 252b) having intermediate ribs between the central portion and the shoulder portions. The tread has intermediate grooves (262a,262b) between the central ribs and the intermediate ribs (266a,266b) and shoulder decoupling grooves (264a,264b) between the intermediate ribs and the shoulder ribs (270a,270b). The shoulder decoupling grooves having a depth (D1) being less than the intermediate decoupling grooves whereby the footprint width of the tread surface can expand from first width (NLFPW) under normal load to a second width (HLFPW) under heavy load.

    摘要: The present invention is a crown-stiffening underlay structure comprised of a flat strip of elastomeric material reinforced with essentially inextensible cords. The cord-reinforced flat strip is wrapped helically around the green tire carcass prior to blowup into the characteristic toroidal shape of a tire carcass. In one embodiment, the underlay structure is disposed between breakers and the radial ply structure. In another embodiment, the underlay is disposed between the radial ply structure and the innerliner. In another embodiment, the afore described underlay structure has an additional and structurally contiguous beam made of elastomeric material.

    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.
