Tire Pressure Monitoring Systems

Posted on by

A Tire Pressure Monitoring System (TPMS) is an electronic alert system in a vehicle that monitors the air pressure inside the tires and advises the driver if the pressure is is not operating within the recommended range.

Types of TPMS

Direct TPMS (dTPMS)

  • Measures actual tire pressure in real time
  • Uses sensors inside each tire (usually attached to the valve stem)
  • Relays data to the vehicle’s dashboard
  • Generally more accurate and common in modern vehicles

Indirect TPMS (iTPMS)

  • Uses wheel speed sensors – Anti-Lock Braking system (ABS)
  • Doesn’t measure pressure directly
  • Generally less accurate but lower cost and no internal sensors
  • Detects underinflation by comparing tire rotation speeds

How TPMS Works

  • Sensors (or software) detect abnormal tire pressure
  • A warning light (often shaped like a horseshoe with an exclamation mark) lights up on the vehicl’e dashboard
  • Some systems show exact pressure for each tire

What are the Benefits of TPMS?

  • Enhances fuel efficiency (proper inflation means less rolling resistance)
  • Increases overall safety by reducing the risk of blowouts
  • Extends tire life by reducing wear

Common TPMS Issues

  • False warnings due to temperature changes
  • Sensor damage during tire changes
  • Dead sensor batteries (especially in direct TPMS)
  • Sometimes requires recalibration after tire replacement or rotation

A Few Maintenance Tips

  • Manually check your tire pressure at least once every 6 weeks
  • Don’t rely solely on TPMS
  • Replace TPMS sensors every 5–10 years (depending battery life)
  • Reset system after inflating or rotating tires (if required)

Choosing the right TPMS for your RV, SUV or Truck

Choosing the right system is vital for safety and reducing costs, particularly for professional drivers and utility vehicle owners. Whether you need a comprehensive system for RV/SUV tire control, do long-haul or extreme weather driving, or need multi-trailer management solutions, we recommend you check out the comprehensive range of TPMS products at GUTA.
