Supplier records
Match company and site identifiers to the quote. IATF 16949 and ISO 9001 evidence describes the supplier's management system within its scope. Review product evidence by SKU and target market separately.

Continental Fitment & Specs
Prepare an RFQ for tires, wheels or wheel-end components. The desk coordinates supplier evidence and sample checks. Fitment and acceptance remain buyer and supplier decisions for the specific application.

Specification matrix
What the supplier needs to confirm
| Product line | Required brief | Comparison and verification |
|---|---|---|
| Passenger & Commercial Tires | Full size and service description, rim diameter, rim width, load index, speed rating, tread pattern, axle duty, quantity and port. | For an illustrative 225/45R18 95W line, confirm that the supplier quote, sidewall and report all use the same size and service description. For dual applications, compare single and dual load tables separately. |
| Off-Road & Specialty Tires | Size, casing or ply designation, rim width, axle load, duty cycle, operating pressure and expected surface. | Compare cut exposure, tread depth and heat constraints at the proposed load and speed. For longer road duty compare rolling resistance and wet grip on a like-for-like test basis. |
| Forged & Cast Alloy Wheels | Vehicle, pitch circle diameter (PCD), wheel offset (ET), center bore, rim width and diameter, load rating, brake envelope and finish. | For an illustrative 5×114.3 pattern and ET35 offset, check the brake envelope and sample drawing independently. Compare forging and casting on measured mass, specified material, finish, validation cost and documented sample availability. |
| Steel & Commercial Vehicle Wheels | Rim structure, bead seat, mounting hardware, load rating, bolt pattern, rim dimensions and corrosion exposure. | Ask the inspector to agree the datum, fixture and buyer acceptance limits for lateral runout and radial runout before comparing readings. |
| Wheel Hub Assemblies | OE cross reference, vehicle platform, hub flange, ABS encoder ring type and wheel speed sensor interface. | Compare the drawing revision and sample. An integrated hub reduces separate bearing setup steps when the specified interface matches. |
| Wheel Bearings & Kits | OE cross reference, bore, outside diameter, width, bearing preload, seal lip and kit contents. | Check installation tools and preload instructions. A serviceable bearing may preserve part-level repair on a compatible platform, subject to installer capability. |
| Wheel-End Accessories & Service Parts | Interface, thread, dimensional drawing, material, finish, platform and pack count. | Check thread engagement, mating seat or valve interface on the specified sample before agreeing a substitute. |
Evidence before commitment
Third-party check
Sample inspection
Log the sample ID, measuring instrument, fixture, reference surface and acceptance limit. Ask the inspector to record readings and photographs against the drawing revision.
Buyer-approved
Document scope
Compare the stated product class, market, test method, amendment, SKU and report date. Review applicability for each product. For light-vehicle radial tire checks, consult the NHTSA test procedures.
Supplier-provided
Commercial basis
Record quantity break, MOQ, Incoterm, named place, packaging and timing for each line. A stock offer and a custom offer need distinct sample and release assumptions.
Third-party check
Lot reconciliation
Use the agreed sampling scope to compare lot markings, quantity and visible condition. Resolve any discrepancy with the supplier before authorizing consolidation.
Buyer-approved
Substitution record
Record the dimensions or performance limits that changed, the evidence reviewed and the person approving the revised quote. Keep pending variants separate from approved lines.
