Abstract
Abstract A wheel includes a well base rim, also known as a drop center rim, the well of which is offset from the median plane of the rim so as to be farther from one edge of the rim than from the other. The junction between the rim and the wheel disk is in the vicinity of the edge of the rim that is the farther from the well.

Claim 1
Independent Claim
228 words
A wheel for vehicles in the heavy-duty class comprising a drop center rim, said rim being formed with a circumferential well which is offset from the median plane of said rim so as to be farther from one edge of said rim that from the other, said rim being asymmetrical with respect to all planes that intersect said rim and that are normal to the axis of said rim, a disk, and a weld effecting a junction between said rim and said disk, said weld junction being adjacent to the edge of said rim that is the farther from said well, wherein the ratio of the distance from the median plane of said well to the farther of said edges to the distance from the median plane of said well to the nearer of said edges is at least 1.45, and wherein all portions of said rim between the bottom of said well and said weld junction are inclined with respect to the axis of said rim at an angle not exceeding 60*, said rim being further formed, between said well and said edge that is the farther from said well, with a bead seat and, between the bottom of said well and said bead seat, with at least one part rounded in axial profile, said rounded part having a radius of curvature of at least 25 mm.
Claim 2
Dependent Claim

A wheel for vehicles in the heavy-duty class comprising a drop center rim, said rim being formed with a circumferential well which is offset from the median plane of said rim so as to be farther from one edge of said rim that from the other, said rim being asymmetrical with respect to all planes that intersect said rim and that are normal to the axis of said rim, a disk, and a weld effecting a junction between said rim and said disk, said weld junction being adjacent to the edge of said rim that is the farther from said well, wherein the ratio of the distance from the median plane of said well to the farther of said edges to the distance from the median plane of said well to the nearer of said edges is at least 1.45, and wherein all portions of said rim between the bottom of said well and said weld junction are inclined with respect to the axis of said rim at an angle not exceeding 60*, said rim being further formed, between said well and said edge that is the farther from said well, with a bead seat and, between the bottom of said well and said bead seat, with at least one part rounded in axial profile, said rounded part having a radius of curvature of at least 25 mm.
Claim 3
Dependent Claim
242 words
A wheel assembly comprising a tire, bead wire means positioned in said tire, a drop center rim for mounting said tire, said rim being formed with a circumferential well which is offset from the median plane of said rim so as to be farther from one edge of said rim than from the other, said rim being asymmetrical with respect to all planes that intersect said rim and that are normal to the axis of said rim, a disk, and means effecting a junction between said rim and said disk, said junction being in the vicinity of the edge of said rim that is the farther from said well, wherein the ratio of the distance from the median plane of said well to the farther of said edges to the distance from the median plane of said well to the nearer of said edges is at least 1.45, wherein all portions of said rim between the bottom of said well and said junction are inclined with respect to the axis of said rim at an angle not exceeding 60*, wherein said edge of said rim that is the farther from said well is defined by a curved flange facilitating retention on said rim of said tire, wherein said rim is formed with a bead seat adjacent to said flange, and wherein said junction is between said flange and a perpendicular projection onto said seat of the center of said bead wire means.
