Abstract
Abstract This invention relates to a tire to be utilized on a cambered wheel assembly of an aircraft. The tire of this invention has its ground-engaging tread surface laterally offset in relation to the medial plane of the tire carcass and is mounted in the cambered wheel assembly so that the offset caused by the camber of the cambered wheel assembly is compensated for by the offset of the ground-engaging tread surface of the tire.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
117 words
A cambered wheel assembly for an aircraft tire comprising a leg, an axle, a rim, and an asymmetric tire; a said leg connecting said aircraft to said axle, said axle connecting said rim to said leg, said asymmetric tire mounted on said rim; said tire having a standard carcass and a ground-engaging tread surface comprised of tread material and mounted on said carcass; the improvement comprising said asymmetric tire having its tread material laterally offset in relation to the median plane of said carcass so that the said tread surface is laterally offset thereby compensating for the offset caused by the camber in said cambered wheel assembly when said tire is mounted in said cambered wheel assembly.
Claim 2
Dependent Claim
117 words
A cambered wheel assembly for an aircraft tire comprising a leg, an axle, a rim, and an asymmetric tire; a said leg connecting said aircraft to said axle, said axle connecting said rim to said leg, said asymmetric tire mounted on said rim; said tire having a standard carcass and a ground-engaging tread surface comprised of tread material and mounted on said carcass; the improvement comprising said asymmetric tire having its tread material laterally offset in relation to the median plane of said carcass so that the said tread surface is laterally offset thereby compensating for the offset caused by the camber in said cambered wheel assembly when said tire is mounted in said cambered wheel assembly.
Claim 3
Dependent Claim
30 words
The cambered wheel assembly of claim 1, wherein said offset of said ground-engaging tread surface is approximately equal to said offset caused by the camber in said cambered wheel assembly.
Claim 4
Dependent Claim
95 words
An asymmetric aircraft tire for a cambered wheel assembly having a carcass and a ground-engaging tread surface comprised of tread material and mounted on a said carcass, said tread material laterally offset in relation to the median plane of the said tire carcass so that the median plane of said ground-engaging tread surface is laterally offset approximately 5* to 10* in relation to said median plane of said tire carcass thereby compensating for the offset caused by the camber in the cambered wheel assembly when the said tire is mounted in said cambered wheel assembly.
Claim 5
Dependent Claim
95 words
An asymmetric aircraft tire for a cambered wheel assembly having a carcass and a ground-engaging tread surface comprised of tread material and mounted on a said carcass, said tread material laterally offset in relation to the median plane of the said tire carcass so that the median plane of said ground-engaging tread surface is laterally offset approximately 5* to 10* in relation to said median plane of said tire carcass thereby compensating for the offset caused by the camber in the cambered wheel assembly when the said tire is mounted in said cambered wheel assembly.
Claim 6
Dependent Claim
97 words
An asymmetric aircraft tire for a cambered wheel assembly having a standard tire carcass and a ground-engaging tread surface comprised of tread material and mounted on said carcass, said tread material laterally offset in relation to the median plane of said tire carcass thereby laterally offsetting the median plane of said tread surface approximately 5* to 10* in relation to said median plane of said standard tire carcass so that the resulting asymmetry will compensate for the offset caused by the camber in the cambered wheel assembly and resulting in the tread surface uniformly engaging the ground.
Claim 7
Dependent Claim
97 words
An asymmetric aircraft tire for a cambered wheel assembly having a standard tire carcass and a ground-engaging tread surface comprised of tread material and mounted on said carcass, said tread material laterally offset in relation to the median plane of said tire carcass thereby laterally offsetting the median plane of said tread surface approximately 5* to 10* in relation to said median plane of said standard tire carcass so that the resulting asymmetry will compensate for the offset caused by the camber in the cambered wheel assembly and resulting in the tread surface uniformly engaging the ground.
