◎Exact wheel scope
Request the manufacturer, part identifier and drawing revision. The drawing should cover wheel diameter and rim width in inches, bolt pattern, signed offset and center bore in millimeters, and the load rating with units. Ask the bidder to call out any deviation and to label the shown wheel position if the order is staggered.
▤Samples and inspection
Separate a finish sample from a production-representative wheel. Record which dimensions the sample can confirm and what needs an actual fit check. Request the applicable test report and check that the sample or drawing revision in the report matches the proposed part.
◇Delivery and exclusions
Use one ship-to ZIP and ask what the quote includes through that point. Separate wheel, hardware, protective packaging, freight, duty assumptions and any sample or tooling fee. Mark unanswered lines as open so the comparison does not treat missing costs as zero.
