A regional fleet asks for steer and drive tires in one order. Split the request by axle position, size and single or dual load index. Before comparing the freight line, check that both quotes use the same units per SKU, packing basis and named destination. If one quote substitutes a drive pattern, mark it as an alternate rather than blending its price into the base offer.

An aftermarket catalog has two plausible matches against one OE cross reference. Keep the hub flange dimensions, connector, ABS encoder ring type and mounting hardware on separate quote lines. Request a sample drawing or interface evidence before treating the assemblies as interchangeable. A dimensional fit can still leave a wheel speed sensor mismatch.
Send the part or size list and identify the price basis you need. The selected supplier confirms MOQ, availability and lead time for the quoted SKU.
