摘要:
A high aspect ratio agricultural pneumatic tire has a carcass including a pair of bead portions each having a bead core and two pair of first and second carcass plies of synthetic cords oriented radially and wrapped from the inside of each bead core around to an axially outer turnup end. The first pair of plies is radially inward and adjacent the second pair of plies between the bead cores and having the turnup ends T1, T1′ wrapped about the bead cores and the turnup ends T2, T2′ of the second pair of plies. The turnup end of the first pair of plies extends outwardly and radially along the bead filler wherein T1, T1′ are located between 60% and 80% of the radial location Y of maximum section width (SW) of the tire and T2, T2′ are located between 30% and 50% of Y.

A pneumatic run-flat tire has a bead configuration wherein the axially inner end is radially inward of the axially outer end of the bead. The sidewall of the tire, from the bead region to the upper sidewall is reinforced to form a pillar support in the sidewall. The bead configuration and the pillar reinforcement enable the tire to lock itself onto a tire rim during low pressure operation and be self-supporting.

A pneumatic radial tire has a carcass and a tread. The carcass has at least one carcass reinforcing ply and opposing bead portions. Each bead portion has a bead core and a bead apex radially. The apexes in each bead portion having the same radial height (HA), as measured from a bead base line (B). The tire has a bead reinforcing ply comprising aramid fiber reinforcing cords located in only one bead portion of the tire, with the bead reinforcing ply being adjacent to the carcass reinforcing ply.

Disclosed are improved wheels and tires for simulating the appearance of larger-diameter wheels mounted within low-profile tires. The improved tires are intended to be mounted on wheels with an extended outer flange. An embodiment of the tire comprises an outboard tire wall, an inboard tire wall, a tread therebetween, a laterally extending wheel protector, a ledge, and a flange seat. The flange seat is optionally contoured to match the inner face of an outer flange of the improved wheel.

The invention is directed to a high aspect ratio agricultural pneumatic tire having a tread, a belt reinforcing structure and a carcass. The tread includes a circumferential inner tread and a plurality of lugs each projecting radially outward from the inner tread. The belt reinforcing structure includes four or more belt layers reinforced by synthetic cords and underlying the tread. The carcass has a pair of bead portions each having a core and a bead filler above each bead core and two pair of first and second carcass plies. Each ply is reinforced by synthetic cords oriented radially and wrapped from the inside of each bead core around to an axially outer turnup end. The first pair of plies is radially inward and adjacent the second pair of plies between the bead cores and having the turnup ends wrapped about the bead cores and the turnup end of the second pair of plies. The turnup end of the first pair of plies extends outwardly and radially along said bead filler to a terminal end T1, T1′ and said turnup ends of said second pair of plies extends to turnup ends T2, T2′ wherein T1, T1′ are located between 60% and 80% of a location Y defined as the radial location of maximum section width (SW) of the tire and the second pair of plies have the terminal ends T2, T2′ extend above the bead cores to a location 30% to 50% of Y. The aspect ratio is preferably greater than 85%, more preferably about 90% or greater. The ply cords are nylon and the belt cords are aramid to form a substantially synthetic textile carcass.

A pneumatic tire comprises a tread portion, a pair of sidewall portions, a pair of bead portions, a carcass, a belt, and a reinforcing member arranged in a tire zone including at least the sidewall portion, wherein a shearing rigidity in the circumferential direction of the reinforcing member is made larger at a first tire zone located at an outside of the vehicle than at a second tire zone located at an inside of the vehicle in the same tire at a posture of mounting the tire onto a vehicle.
摘要:
A pneumatic tire is capable of operation during underinflated condition and the construction of sidewalls are configured to compensate for negative cambers acting upon the tire. The inboard side of the tire is softened in comparison to the outboard side of the tire. This is achieved by either forming an asymmetrical tire in either the tire profile or the internal construction.
摘要:
The present invention provides an improved wheel and tire for simulating the appearance of a larger-diameter wheel mounted within a low-profile tire. The wheel has an inboard side and an outboard side. The outboard side includes a wide outer flange which extends around the outer circumference of the wheel. The outer flange and/or the outboard face of the wheel is preferably detachable from the remainder of the wheel. The inboard side may include a wide inboard flange which is preferably detachable. The flanges preferably cover a substantial portion of the wall of the outer tire within which the wheel is mounted. A design, preferably comprised of, for example, a plurality of protrusions, indentations, and slits, extends across at least a portion of the outboard face of the wheel, including the outboard face of the extended outer flange.
摘要:
The present invention is directed at a tire design, which allows for proper operational characteristics in all operating conditions, and is not dependent on pneumatic pressurization. The tire is mounted in a wheel rim, and comprises an integral homogeneous toroidal body having a pair of spaced-apart radially extending sidewalls and a cross member. Each sidewall has a first and a second end and an internal face and an external face, with the second end of each of the sidewalls integrally merging into the cross member. A set of rim-engaging surfaces at the first end of each of the sidewalls allows effective mounting to conventional tire rims. An annular chamber is defined by the internal faces of the sidewalls and an internal top wall on the cross member opposite the at least one road engaging surface. The set of rim-engaging surfaces includes a lobe-like portion at the first end of each of the sidewalls, the respective lobe-like projections may be separable when the tire is not mounted on the rim, but being compressed into engagement when the tire is mounted in the rim, thereby closing the annular chamber, or integral with one another to form the enclosed chamber.
