The tire includes a bead portion further having an apex which extends radially outward of the bead core, and a turn-up pad located adjacent said chafer. The turn-up pad has a minimum specified width and a maximum specified width at a Radius R as measured from the bead center. The turn-up pad is formed of a material having a specified G′ and G″.
Claims13
A pneumatic tire comprising a carcass, the carcass having one or more cord reinforced plies and a pair of bead portions, each bead portion having at least one annular inextensible bead core about which the cord reinforced plies are wrapped, a tread and a belt reinforcing structure disposed radially outward of the carcass, the bead portion further comprising an apex which extends radially outward of the bead core, and a chafer, the tire further comprising a turn-up pad located adjacent said chafer, wherein the turn-up pad has a minimum thickness in the range of about 1.0 inches to about 2.0 inches.
A pneumatic tire comprising a carcass, the carcass having one or more cord reinforced plies and a pair of bead portions, a tread and a belt reinforcing structure disposed radially outward of the carcass, each bead portion having at least one annular tensile member about which the cord reinforced plies are wrapped, said one or more plies having a turndown portion which extends from the crown and axially inward of the annular tensile member, and a turnup portion which extends radially outward from the annular tensile member and axially outward of the annular tensile member, wherein the gauge between the turnup portion of the ply and the turndown portion of the ply is less than 1.6 inches.
A pneumatic tire comprising a carcass, the carcass having one or more cord reinforced plies and a pair of bead portions, each bead portion having at least one annular inextensible bead core about which the cord reinforced plies are wrapped, a tread and a belt reinforcing structure disposed radially outward of the carcass, the bead portion further comprising an annular tensile member and an apex which extends radially outward of the bead core, wherein the annular tensile member has a width in the range of about 2.5 inches to about 2.7 inches and a chafer.
