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： 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 invention relates to a pneumatic tire with a toroidal shaped tire carcass having sidewalls and a tread. The tire carcass terminates at opposite bead regions for mounting on a tire rim. The tire has at least one of the sidewalls having a circumferentially extending continuous groove, and a non-rubber inlay ring secured within the continuous groove of the sidewall(s) to form a rim flange protector.

摘要： A pneumatic radial ply runflat tire (200) has a tread (210), belt structure (212), a carcass (216), and an underlay (234) disposed between the belt structure and the carcass. The carcass (216) comprises two sidewalls (226), two beads (220), and one or more radial plies (222,224). The tire (200) is characterized by the underlay (234) having reinforcement cords (236) with turns aligned parallel to the tire's equatorial plane, the cords (236) exhibiting negligible modulus of elasticity (“modulus”) below a threshold elongation and high modulus above the threshold elongation. The underlay (234) stiffens the tire during runflat operation but not during normal inflated operation.

摘要： A pneumatic tire with an increased load carrying capacity (extended load index) but compatible with conventional, commercially available wheel rims, has a modified carcass plyline. The tire has a tread area, a carcass structure including two bead areas each comprising a bead, at least one cord-reinforced elastomeric ply extending between the two bead areas, and two sidewalls, one sidewall extending between the tread area and each bead area. The tire is characterized by: a section width defined by lines L1 and L2 disposed orthogonally to an axis of rotation of the tire and at equal distances on either side of the equatorial plane of the tire; a plyline that follows the meridional path of a radially and axially outermost one of the at least one ply; points P1, P2 on the plyline, being located where the plyline is axially outside of one of the beads and simultaneously at a minimum radial distance of dp1, dp2, respectively, from the axis of rotation AR; lines M1 and M2 each parallel to, and axially inwards of, lines L1 and L2, respectively, and passing through points P1 and P2, respectively; a first distance of 1 mm to 5 mm being the spacing from line L1 to line M1, and from line L2 to line M2; limiting radial distances r1 and r2 that exceed the distances dp1 and dp2, respectively, by a value of 30% to 70% of a section height SH of the tire; and the plyline extending radially outward in each sidewall to the limiting radial distance r1, r2 without axially deviating from lines M1, M2, respectively, by more than a second distance of 0 mm to 5 mm.

摘要： A self-supporting pneumatic tire, capable of continued operation during under-inflation conditions, has at least one insert located in each tire sidewall. Forming the interior surface of the self-supporting tire is a stiffening layer of material having characteristics similar to that of the insert. In the tread region of the tire, and radially inward of the innermost carcass layer, and possibly in the interior bead region of the tire, is a partial inner liner layer of the bromobutyl rubber.
