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.

Tire tread

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.

A passenger car tire that combines a number of design features or parameters which yeild a tire which has road noise, tread wear and handling performance characteristics which are equal to or better than those exhibited by comparable prior art tires, which possesses improvements in mud and snow performance not heretofore approached in prior art high performance tires, and in which heat dissipation characteristics are such that ornamental white sidewall lettering may be applied without in any way detracting from performance and durability characteristics. Moreover, and most surprisingly, the tire of the present invention is actually lighter in weight than is the most comparable prior art high performance tire, which does not possess the improved mud and snow characteristics of the invention.
