A radial ply pneumatic tire has a carcass with a bead portion, a carcass reinforcing structure, and a bead filler. The carcass reinforcing structure has at least two structures with cords which extend to each bead. In a preferred embodiment of the invention, the tire carcass includes elastomeric first and second fillers, the first filler being located between the first ply structure and the innerliner of the tire, and the second filler being located between the first and second ply structures. The fillers stiffen the sidewalls to permit the tire to be driven while uninflated. The tire further includes an aramid overlay radially outwardly of the reinforcing belt.

Radial ply pneumatic runflat tire

A radial ply pneumatic tire has a carcass with a bead portion, a carcass reinforcing structure, and a bead filler. The carcass reinforcing structure has at least two plies. The turnup ends of a first or a second ply are wrapped about each bead and terminates in radial proximity of the maximum section width of the tire. In a preferred embodiment of the invention, the tire carcass includes elastomeric first and second filers the first filler being located between the first ply and the innerliner of the tire, and the second filer being located between the first and second ply. The fillers stiffen the sidewalls to permit the tire to be driven while uninflated. The tire may further include an aramid overlay radially outwardly of the reinforcing belt.

Radial ply pneumatic tire

A radial ply pneumatic tire features a bead core which comprises an arrangement of filaments positioned relative to one another. The bead core has a cross-section and radially inward base side, a radially outermost point or side or sides, an axially inward first side, and an axially outward second side. The base side of the bead core is substantially linear and has a width being between 50% to 75% of the rim seat width. An associated rim has a pair of humps and a rim flange associated with each hump. Each rim flange has an axially inward surface, the distance between each hump and the axially inward surface of the associated rim flange being a rim seat.

Pneumatic tire having specified bead structure

A radial ply pneumatic tire is described. The tire has a carcass with a bead portion, a carcass reinforcing structure, and a bead filler. The carcass reinforcing structure has at least two plies. The turnup ends of a first and second ply are wrapped about each bead. The turnup end of one of the plies terminates in radial proximity of the maximum section width of the tire. In a preferred embodiment of the invention, the tire carcass includes elastomeric first and second fillers the first filler being located between the first ply and the innerliner of the tire, and the second filler being located between the first and second ply. The fillers stiffen the sidewalls to permit the tire to be driven while uninflated. The tire may further include an aramid overlay radially outwardly of the reinforcing belt.

The turn-up portion of the carcass ply (12) in the bead portion of a pneumatic tire is interposed between the bead core (11) and a toe guard (18), and extends a substantial distance toward the maximum section width of the tire. The bead core (11) has a radial cross section which is substantially pentagonal. The toe guard (18) comprises a rubber material, a flexible textile material or a heat shrinkable material that protects the toe portion of the tire. Elastomeric stiffening member or chafer (20) may be disposed on each side of the carcass ply (12) in the bead portions and lower sidewalls of the tire. The assembly of a tire according to the invention mounted upon a specified rim (22) is also disclosed.

Pneumatic tire having a high ending, turnup locked bead construction

A radial ply pneumatic tire is described. The tire has a carcass with a bead portion, a carcass reinforcing structure, and a bead filler. The carcass reinforcing structure has two plies with turnup ends wrapped about each bead. The turnup end of the first ply terminates in radial proximity of the maximum section width of the tire. In a preferred embodiment of the invention, the tire carcass includes elastomeric first and second fillers the first filler being located between the first ply and the innerliner of the tire, and the second filler being located between the first and second ply. The fillers stiffen the sidewalls to permit the tire to be driven while uninflated. The bead core of the preferred embodiment has a flat base and a first and second surface extending from the base and inclined relative to the base thereby forming acute included angles of .alpha. and .beta. whereby .alpha. is greater than or equal to .beta.. The tire may further include an aramid overlay radially outwardly of the reinforcing belt.

A radial ply pneumatic tire features a bead core which comprises an arrangement of filaments positioned relative to one another. The bead core has a cross-section and a radially inward base side, a radially outermost point or side or sides, an axially inward first side, and an axially outward second side. The first side intersects the base side at a first edge and forms thereby an included angle .alpha.. The second side intersects the base side at a second edge and forms thereby an included angle .beta.. Angle .alpha. is greater than or equal to .beta.. The bead core has a perimeter comprising the lengths of the base, radially outermost, first, and second sides. The perimeter define a bead core area which is less than the area of an isosceles triangle having acute angles equal to .alpha.. The width of the bead heel surface is approximately equal to the distance between a hump and an axially inward surface of the wheel flange.

Pneumatic radial tire including steel belt cords of 2+2 ST construction

The turn-up portion of the carcass ply (12) in the bead portion of a pneumatic tire is interposed between the bead core (11) and a clamping member (18). The bead core (11) has a radial cross section which is substantially pentagonal. The clamping member (18) comprises a heat shrinkable material that secures the turn-up portion of the carcass ply in a desired location. Elastomeric stiffening members (19,20) are disposed on each side of the carcass ply (12) in the bead portions and lower sidewalls of the tire. The assembly of a tire according to the invention mounted upon a specified rim (22) is also disclosed.
