Tire pressure monitoring rule rejected by appeals court.
A federal appeals court threw out a regulation requiring tire pressure monitors in vehicles as "arbitrary and capricious." The 2nd U.S. Circuit Court of Appeals eliminated the federal rule, which would have required monitors that alert drivers to underinflated tires in all vehicles made after November. Three nonprofit consumer advocacy organizations challenged the rule in a lawsuit, saying the government, under pressure from automotive companies, adopted a less safe standard than it should have. The appeals court agreed, noting that the system the government required would have failed half the time to warn drivers when tires were underinflated. The rejected rule would have allowed automakers to choose between a less expensive indirect system that would work off the antilock braking system and a more accurate direct system of monitors in each wheel.
