6. Description of content:  This notice of proposed rulemaking (NPRM) proposes to establish 
a new Federal motor vehicle safety standard  mandating tire pressure monitoring systems 
capable of detecting when a tire is significantly under-inflated. A prior version of the 
standard, adopted by the agency in June 2002 in  response to a mandate in the Transportation 
Recall Enhancement, Accountability and Docume ntation Act, was vacated by a decision 
issued by the U.S. Court of Appeals for the Second Circuit in August 2003. This NPRM, which is consistent with the Court's decision, proposes to re quire installation in new light 
vehicles of a tire pressure monitoring system cap able of four-tire, 25-percent under-inflation 
detection. This proposed rule differs from the fina l rule also in that it tentatively responds to 
issues raised in petitions for reconsiderati on of the June 2002 final rule and proposes to 
require a TPMS malfunction indicator.
