What to enter in a sourcing brief
Numbers in the table illustrate how to record a specification. Use the approved drawing and requirements for the application.
| Product family | Fields to submit | Check before a release |
|---|---|---|
| Forged and cast alloy wheels | Vehicle, axle, rim diameter × rim width in inches, pitch circle diameter (PCD) such as 5×114.3 mm, wheel offset (ET) such as ET35, center bore, load rating in kg, finish and target market. | Check brake and fastener clearance on the intended vehicle. For a sample, agree the mounting datum and gauge locations for radial runout and lateral runout. |
| Steel and commercial wheels | Rim diameter and width, mounting profile, bead seat, axle position, load per wheel, coating and corrosion exposure. | Match the quoted drawing to the hub and mounting hardware. Ask which load and duty the supplier evidence covers. |
| Passenger and commercial tires | Size such as 225/45R18, load index, speed rating, tread pattern, duty, quantity and destination port. | Compare wet grip, rolling resistance and tread depth against the intended duty. Match requested documents to the quoted size and market. |
| Off-road and specialty tires | Size, carcass or ply rating, load and speed limits, duty cycle, terrain, tread pattern, quantity and destination. | Ask for the conditions behind cut and heat resistance claims. Record speed, surface and loading separately for distinct duty cycles. |
| Wheel hub assemblies | OE cross reference, vehicle/VIN where required, axle, hub flange, ABS encoder ring, wheel speed sensor interface, seal and hardware. | Confirm the flange and encoder interface together. Ask for a sample ID, drawing revision and the sensor compatibility check. |
| Wheel bearings and kits | OE reference, bore, outside diameter and width in mm, bearing preload requirement, seal lip design and included kit parts. | Compare integrated and serviceable options against the actual hub. Document any required press tools, replacement fasteners and installation procedure. |
| Wheel-end accessories | Vehicle platform, size, thread pitch, seat geometry, material, surface finish and packaging. | Verify mating surfaces and thread engagement on the proposed assembly. Record packaging and labeling separately from component specifications. |
For a mass-sensitive wheel program, compare a forging and a casting at the same fitment, load and finish. Use measured sample weight and construction-specific test evidence. For replenishment, a matching stock design can avoid tooling, while a custom drawing gives control over offsets and finishes and needs its own sample approval.
Evidence before commitment
Drawing match
Compare the buyer-approved drawing number, dimensional tolerances and revision to the supplier quote and sample label.
Third-party report scope
Ask which model, size, rated load, report revision and market a report or approval covers. Record open questions with the issuer or responsible importer.
Sample check
Agree the fixture, mounting datum, instrument and rotation procedure before measuring runout. Record the reading, sample ID and drawing limit.
Buyer disposition
Record the buyer's acceptance, exception or repeat-sample request. Keep approvals specific to the selected revision and configuration.
Shipment file
Check carton labels and quantities against the packing list. Mark any mixed-container loading and lot-separation instructions.
