B: US DOT: NHTSA Proposes Standard for Tire Pressure Monitoring Devices ( M2
PRESSWIRE )
(Comtex 09/16 04:08:39)

Sep 16, 2004 (M2 PRESSWIRE via COMTEX) -- The U.S. Department of
Transportation's National Highway Traffic Safety Administration (NHTSA)
today
proposed a new safety standard to warn the driver when a tire is
significantly
under-inflated.

The proposal requires manufacturers to install a four-tire Tire Pressure
Monitoring System (TPMS) that is capable of detecting when a tire is more
than
25 percent under-inflated and warning the driver.

The new standard also proposes to add a TPMS malfunction indicator to the
requirements, which would warn the driver when the system is not working
properly. For example, sometimes tires are installed on the vehicle that are
incompatible with the TPMS, or sometimes other problems cause the TPMS to
become
inoperative.

TPMS is a safety warning system and is not a substitute for regular tire
pressure maintenance by drivers. Operating a vehicle with substantially
under-inflated tires can result in a tire failure, such as instances of
tread
separation and blowouts, with the potential for a loss of control of the
vehicle. Under-inflated tires also shorten tire life and increase fuel
consumption.

The new Federal Motor Vehicle Safety Standard would apply to passenger cars,
trucks, multipurpose passenger vehicles, and buses with a gross vehicle
weight
rating of 10,000 pounds or less, except those vehicles with dual wheels on
an
axle.

The new standard proposes the following three-year phase-in schedule: In the
first model year, beginning Sept. 1, 2005, 50 percent of all light vehicles
manufactured would comply.

In the second model year, beginning Sept. 1, 2006, 90 percent of all light
vehicles manufactured would comply.

After Sept. 1, 2007, all light vehicles manufactured would comply.

NHTSA will accept comments on this notice of proposed rulemaking for the
next 60
days (http://www.nhtsa.dot.gov/cars/rules/...SnprmPost2Cir/
TPMSnprmP).
Written comments concerning the proposal should be sent to the DOT Docket
Facility, Attn: Docket No.
