Federal regulators proposed on September 15 that, starting in 2007, all vehicles be equipped with warning lights telling drivers when their tire pressure is low, according to the Pittsburgh Tribune-Review.
The rule would require vehicles to have a yellow light that would illuminate when the pressure on any one of the four tires was underinflated by 25 percent or more. The National Highway Traffic Safety Administration (NHTSA) said the proposal would likely cost up to $69.89 per vehicle, or a total of $1.1 billion for the industry. But the agency said the requirement would save as much as $1.7 billion in fuel and vehicle maintenance costs. Dan Zielinski, a spokesman for the Rubber Manufacturers Association, said tire makers will protest the proposal because it disagrees with setting a flat rate of 25 percent underinflation.
