Send your specRecord unknowns as open items. Confirm fitment and evidence before approving a sample or committing to an order.
Send rim diameter, rim width, PCD, wheel offset, center bore, bolt seat, load rating and surface finish. Include the brake envelope and target market.
Compare forged and cast proposals at the same load and mounting geometry. Request material, drawing revision and sample evidence before comparing mass and tooling charges.
List size, load index, speed rating, tread, duty cycle, quantity and destination. For example, 225/45R18 names the size but leaves the service description and application open.
Ask for rolling resistance, grip and wear evidence under comparable conditions. Record test method and conditions alongside the result.
