Application and destination
Separate the vehicle application from the destination market. The first drives geometry and load. The second shapes the documents the buyer needs to review.
Build separate rows by axle, trim and brake package. For an alloy wheel quote, compare PCD, center bore, ET, rim width and load against the same baseline. If a supplier supplies an SAE J2530 report, check the reported wheel family and size with the buyer’s reviewer before relying on it.
For tires in the same program, send the size designation, load index, speed rating and duty cycle. Ask the reviewer which tire evidence applies to that SKU and market.
Include the model variant, original wheel size and brake clearance. Ask the buyer’s reviewer to establish whether a replacement wheel falls in scope for UNECE R124, then check that any approval document identifies the offered wheel and covered application.
When a supplier offers two finishes, confirm which finish is represented by the sample and how visible and hidden surfaces will be judged.
Keep destination, load rating, finish and carton language on each purchase-order line. For hot or abrasive operating conditions, describe the duty cycle so suppliers can respond with application-specific evidence.
For a hub assembly, confirm the OE cross reference, hub flange and ABS encoder. Compare an integrated hub quote with a serviceable bearing only where both meet the vehicle requirements. Consider installation tools, preload and parts to keep in stock.
These bars count the fields listed here for each review. They describe the brief itself.
Agree on the mounting datum and gauge location for runout checks. Keep the sample identifier and result together, and refer wheel or caliper interference to a qualified reviewer before release.
For a mixed order, identify each destination and tell us which wheel, tire or wheel-end part belongs to it.
