Practice question

What equipment can help detect tire pressure issues?

  1. Manual pressure gauges only
  2. Tire pressure monitoring systems (TPMS)
  3. Visual inspections by the driver
  4. Air compressors

Answer: B — Tire pressure monitoring systems (TPMS)

A tire pressure monitoring system (TPMS) is specifically designed to monitor the air pressure inside the tires and provide real-time information to the driver. This system alerts the driver when tire pressure drops below a certain threshold, which can help prevent issues such as reduced fuel efficiency, poor handling, and increased tire wear. While manual pressure gauges and visual inspections can also identify tire pressure issues, they rely on the driver to either check the tire pressure at intervals or visually inspect the tires for signs of low pressure, which may not be as immediate or reliable. Air compressors are used to inflate tires but do not provide any information about the current tire pressure. Thus, the TPMS stands out as an essential tool for proactively maintaining proper tire pressure and safety on the road.
