Understanding Tire Pressure Monitoring Systems

Tire Pressure Monitoring Systems (TPMS): A Safety Essential

The U.S. Department of Transportation's National Highway Traffic Safety Administration (NHTSA) has mandated TPMS in most passenger vehicles, requiring them to alert drivers when a tire is significantly underinflated.

Why is proper tire pressure important?

• Safety: Underinflated tires can lead to premature wear and blowouts, posing a serious safety risk.
• Fuel efficiency: Underinflation can reduce fuel economy by up to 10%.
• Tire life: Underinflated tires wear out 30% faster than properly inflated ones.

How TPMS works

• Direct systems use sensors within the tire to measure pressure and transmit data to a receiver.
• Indirect systems use the vehicle's anti-lock braking system to estimate tire pressure based on wheel speed differences.

Maintaining TPMS

• Regular checks: Monitor tire pressure monthly and ensure all tires, including the spare, are properly inflated.
• Sensor maintenance: Replace the nickel-plated valve core, rubber grommet, and locking ring when servicing tires.
• Battery life: TPMS sensors typically have a battery life of around 7 years. Use a TPMS tool to check battery status.
