Cross-check tire fitment, normalize quotations and request model-level evidence. Use the same size and service description across your catalog, sample brief and shipment record.
Use a reference row such as 225/45R18 95W with the approved rim, tread pattern and target market. Cross-check the supplier SKU against the size and service description. Document a different load index or speed rating as a proposed substitution for fitment review.
Record the sample lot, photographs of the sidewall, tread depth in millimeters and the approved comparison specification. A 225/45R18 95W sample marked with a different load index or speed rating from the quote stays open until the buyer resolves the discrepancy. Record the exact tire size and approved rim as well as the markings. Record any exception against its acceptance criterion and identify who will decide whether the sample can proceed.
Match the document issuer, manufacturing site, product family, SKU and target market. Evaluate ISO or IATF system scope separately from any tire-category or SKU evidence for the intended market.
Compare existing and custom options on MOQ per size, sample cost, labeling and lead-time basis. Stock can simplify a repeat order. Custom supply can address a pattern or marking gap, with a separate approval step and quantity threshold to confirm.
Request the method and revision, exact specimen, conditioning, inflation, load, speed, surface and measured result as applicable. Use equivalent test conditions to compare rolling resistance and wet grip. For a buyer comparing a highway option with a mixed-road option, ask both suppliers for results for the same tire size under comparable load and speed. Consider tread life and tread depth against the actual duty cycle, and keep absent or out-of-scope results open in the comparison.
Check the offered and packed quantity by SKU, lot or date-code rules and the destination port. If splitting between suppliers, resolve packaging and labeling differences before the forwarder reviews the load plan.
Agree on exact fitment fields, quantity by size and the receiving market.
Hold currency, Incoterm, named place and packaging basis constant.
Match the sample, checks and any applicable market evidence to the offered SKU.
Send the buyer the open exceptions and reconcile packing before the forwarder handoff.
