supe Posted January 8, 2007 Report Share Posted January 8, 2007 A light on instrument panels soon will warn motorists when a tire is under inflated. The safety regulation, issued by the government , has its roots in the Firestone tire recall of 2000. It requires new passenger cars by the 2008 model year to have systems to monitor tire pressure. Automakers will attach tiny sensors to each wheel that will signal if a tire falls 25 percent below the recommended inflation. If any of the four tires is under inflated, the sensor sets off a light. The National Highway Traffic Safety Administration estimates the upgrade will cost manufacturers $48.44 to $69.89 per vehicle. The government said under inflated tires affect a vehicle's fuel economy and can increase stopping distances, contribute to the likelihood of tire failure and lead to skidding on wet surfaces. One agency survey said 30 percent of cars and light trucks have at least one tire under inflated by 8 pounds per square inch or more. The regulation affects passenger cars, sport utility vehicles, pickup trucks and minivans. All four-wheel vehicles weighing 10,000 pounds or less must be equipped by the 2008 model year.
