Choose the reason for your inquiry

Sample or dispatch
Include the sample label, lot or packing-list reference. State whether the question concerns the supplier, inspector or forwarder.
Prepare a brief we can route
- Wheel fitment
- State the model year, trim, axle and brake package. A 5×112 bolt pattern can narrow the shortlist, while offset, bore and brake clearance determine the next verification step.
- Tire specifications
- Provide size, load index, speed rating, tread and service duty. For mixed quantities list units by size, not just a container count.
- Wheel-end specifications
- Provide the OE or cross number, vehicle or authorized VIN reference, flange, encoder, bore / OD / width, seal and included hardware.
- Offer boundaries
- Catalog replenishment can reuse an existing drawing if the part is confirmed. Custom work may need a revision and separate sample approval. The supplier confirms quantities, pricing and timing by SKU.
