Evidence Before Commitment

Label each item as supplier-provided, third-party issued or buyer approved. Record which documents still need review.

Supplier Records

For each offer, record the SKU, plant named in the supplier record, revision and quoted Incoterm with named place. Compare prices against the same pack unit, currency and size quantities.

Sample Check

Agree on the lot, sample selection, method and acceptance limits. For tires, capture sidewall markings, tread depth, test load and inflation. For wheels, record the runout fixture, measurement location, units and sample ID.

Document Scope

Check issuer, scope, holder and revision. ISO 9001 and IATF 16949 refer to quality systems. Ask which UNECE or DOT/FMVSS requirement applies to the offered tire and destination before requesting item-level records.

Fitment Cross-Check

Record wheel PCD, offset (ET), center bore, rim diameter and width. For hub assemblies, compare the OE cross reference, hub flange, ABS encoder and wheel speed sensor interface against the same vehicle reference.

Quote Alternatives

Stock and custom offers may differ in size availability, sample approval and SKU minimums. Compare one-source consistency against multi-source coverage, with added inspection and shipment handoffs listed beside the price.

Buyer Acceptance

For a rolling-resistance versus grip comparison, record test conditions and the operating duty before interpreting the results. Ask the buyer to sign off on the selected item, exceptions and remaining checks.
