Federal Motor Vehicle Safety Standards

Riepilogo

This document denies a petition from the Rubber Manufacturers Association (RMA) to conduct rulemaking to amend the Federal motor vehicle safety standard on tire selection and rims to require manufacturers of new motor vehicles to establish a recommended cold inflation pressure (placard pressure) for their vehicles using a tire pressure reserve. The tire pressure reserve would be based on the minimum pressure the RMA believes is necessary to support the vehicle's maximum load at the activation pressure of the installed tire pressure monitoring system (TPMS). The agency has decided to deny the petition because neither the RMA's nor the agency's data demonstrate a safety need for such a requirement.
