Purpose. The disclosure relates to vehicle wheels, methods of making them, and dual wheel assemblies. A classification tag indicates the purpose of reduction of weight (B60B2900/111), with truck/load-vehicle indexing.
Plain-language scope (from the excerpted definitions/claims). A vehicle wheel has a generally cylindrical first region (with outer and inner surfaces) and a second region extending radially inward that mounts to a vehicle axle. The second region includes a first surface, a second surface (their separation defining a thickness), an opening extending between them to receive at least part of the axle hub, and a hub surface adjacent to and surrounding the opening. The hub surface has a generally flat portion and a relief portion adjacent at least one of the first/second surfaces; the relief portion surrounds the opening and extends along the hub surface at least 25% of the thickness.
A dual wheel assembly has two such wheels, with the first surfaces adjacent and the opening central axes coaxial.
A method of making a wheel comprises providing (via at least one of forming, curing, forging, casting, additive manufacturing) a wheel comprising metal and/or metal alloy and having the above structure.
Figures 1A–5 illustrate wheel and dual-assembly cross-sectional details, including relief portions with two segments.
Not established by the excerpt. Full claim text and dependent claims, the complete specification, actual claim coverage, precise dimensions, and the omitted portion of the source remain unverified. Litigation, ownership transfers, validity, and prior art were not examined, per instruction.

PTAB challenges
AIA trial proceedings at the USPTO Patent Trial and Appeal Board — IPR, PGR, and CBM. Petitioners, judge panels, claim-level invalidation outcomes from Final Written Decisions, and Federal Circuit appeals. The single most important defensive datapoint after litigation history.
Assignment history
Inventors, original assignee, and the chain of ownership recorded with the USPTO — including the correspondent attorney who recorded each assignment, since shell-LLC chains often share one repeat-player attorney even when the entity names look unrelated. Surfaces NPE / patent-troll patterns: shell-entity transfers, known asserters in the chain, repeat correspondent fingerprints, pre-litigation assignments, and bankruptcy fire-sales.
Prior art
Earlier patents, publications, and products that may anticipate or render the claims unpatentable.
Obviousness
Combinations of prior art that suggest the claimed invention would have been obvious under 35 U.S.C. § 103.
Extensions
Patent term adjustments, term extensions, continuations, divisionals, family members, and expiration dates.
Derivative works
Defensive disclosure: derivative variations of each claim designed to render future incremental improvements obvious or non-novel.
