1. What is a Tire Pressure Monitoring System (TPMS)?

A Tire Pressure Monitoring System (TPMS) is an electronic system designed to monitor the air pressure inside the tires on a vehicle. According to the National Highway Traffic Safety Administration (NHTSA), TPMS has been mandatory in all new vehicles sold in the United States since 2007 to enhance road safety by alerting drivers to significantly under-inflated tires. TPMS helps prevent accidents, improves fuel efficiency, and extends tire life by ensuring tires are properly inflated.

1.1. Types of TPMS

There are two primary types of TPMS:

• Direct TPMS: Uses pressure sensors inside each tire to measure pressure and transmit data to the vehicle’s computer.
• Indirect TPMS: Relies on the vehicle’s ABS (Anti-lock Braking System) to monitor tire pressure by comparing the rotational speed of the tires.

Direct TPMS provides more accurate readings but requires sensors in each tire, while indirect TPMS is less precise but doesn’t need additional hardware in the tires.

1.2. Importance of TPMS

The TPMS is critical for several reasons:

• Safety: Under-inflated tires can lead to tire failure, increasing the risk of accidents.
• Fuel Efficiency: Properly inflated tires improve fuel economy.
• Tire Life: Maintaining correct tire pressure reduces wear and extends the life of your tires.
