A structured path from vehicle interfaces to a reviewable wheel program.

Support at each decision point

Fitment review

We begin with platform and year, PCD, offset, center bore, diameter and width. Brake clearance, mounting hardware and load requirements complete the interface picture. A wheel should be assessed against the actual vehicle configuration, not a generic fit claim. If aftermarket brakes or suspension parts are fitted, share those changes as well. Measurements and drawings provide a common reference for the first review; missing dimensions can be identified before the project advances.

Design coordination

Discuss forged versus cast construction, spoke geometry, finish and target volume. Each choice affects tooling, manufacturing constraints and the information required for a drawing review. The resulting scope should identify what remains to be verified. Surface finish and manufacturing tolerances should be defined alongside appearance so that the proposal can be assessed against the same expectations by engineering and purchasing teams.

Validation planning

Define samples, test methods and acceptance criteria for the intended market and duty cycle. Documentary evidence should identify the tested product and revision; a management system certificate alone is not product approval. Test selection depends on wheel type, market and intended use. Discuss radial and lateral runout measurement, load cases and sample identification as part of an agreed plan rather than assuming one test applies everywhere.

A reviewable process

01 / Brief

Collect vehicle details, operating loads, target market and quantity.

02 / Review

Compare packaging, material and manufacturing assumptions against the project requirements.

03 / Validate

Agree on the test scope and the evidence needed to close open risks.

04 / Release

Confirm drawing revision, inspection requirements and procurement terms. Any later change should be reviewed for its effect on fitment and the evidence already collected.

Clear gates, explicit evidence

Every proposed gate should name its owner, input and acceptance criteria. Ask for the documents applicable to the specific wheel and destination before making a purchasing decision. A gate can include a drawing review, a sample inspection or a test report, depending on the work agreed. Record open items and the person responsible for closing each one so that the decision trail remains clear.

Start with your specification

Send the dimensions and duty profile you know; identify open questions in the same request.
