Start with the wheel interface

A structured specification makes geometry, loads and the intended vehicle application visible to every reviewer.

Freeze the specification

01

Fitment

Record rim diameter and width, PCD, offset, center bore and available clearance. Include vehicle platform, axle position and mounting hardware so the interface can be reviewed as a whole.

02

Duty and load

Define the load rating, operating environment and relevant duty cycle. A wheel that fits geometrically still needs an assessment against the loads and use conditions.

03

Validation

Set sample quantities, test methods and acceptance criteria before testing. Radial and lateral runout checks belong alongside the agreed mechanical test scope.

04

Traceability

Keep drawing revisions, material records and inspection results linked to the reviewed configuration. Changes should return to the appropriate approval point.

Compare testing scope

Geometry and interface

Dimensional inspection addresses mounting features, rim profile and clearance. Measurement conditions and tolerances should be recorded with the drawing to make results comparable.

Mechanical duty

Rig or road evaluations can address agreed loads and operating conditions. The applicable method, sample and market determine what a result demonstrates.

Fitment record — request applicable platform
Test plan — agree method and acceptance criteria
Inspection record — identify revision and lot

Questions before a program starts

Which dimensions are essential?

Begin with diameter, width, bolt pattern, offset and center bore; provide hub and brake clearance details when available.

Which standard applies?

That depends on wheel type and destination market. Request the relevant evidence instead of assuming that a system certificate is product approval.

Prepare an engineering inquiry

Share your drawing, platform and duty profile to frame a useful technical discussion.
