Direct TPMS – Internal Vs External Sensors

tyre presure

A direct TPMS is an innovative, aftermarket solution which uses battery-powered tyre pressure sensors to measure the actual air pressure inside each tyre, providing real-time data to the driver. There are two types of direct tire pressure monitoring systems (TPMS); internal sensor systems where the sensor is inside the tyre or external systems which use external sensors. Safe T Tyre is proud to be one of Australia’s leading suppliers of TPMS, read on to learn about internal and external systems to determine which one might best suit your needs.

Internal Systems

With sensors that are strapped around the wheel or replace the valve stem and are inside the tyre,

direct TPMS with internal sensors require additional antennas in the wheel wells for reliable reception of signals.

  • They are also more expensive install, requiring additional time for installation.
  • They may have difficulty getting a clean signal, making them a less reliable and accurate option.
  • The sensors can be damaged easily when removing a tyre from the rim.
  • They do not give a pressure reading until the vehicle is moving at least 30km/ph.
  • They only give a low pressure alert only when the tyre is significantly low on pressure.
  • The sensors make it difficult to rotate tyres.
  • They are expensive to maintain.

External Systems

With sensors which read from outside of the tyre, a TPMS with eternal sensors is easier to install, maintain and use. 

  • They are less expensive, quick, and easy to install, simple to use.
  • They do not require antennas in each wheel well.
  • The sensors give a reliable, strong, and clear signal.
  • They alert to low pressure and display current pressures even while parked.
  • The sensors can be re-programmed to new positions or switched to new vehicles easily, quickly and without hassle.

Why is a TPMS Important?

Tyre pressure monitoring systems (TPMS) alert the driver when one or more tyres are significantly under-inflated, possibly creating unsafe driving conditions. Whilst a TPMS is designed to improve vehicle safety, it also provides many other benefits.

  • Increased Fuel Efficiency – Every 10% reduction in pressure results in approximately 1% reduction in fuel. Therefore, to ensure optimal fuel efficiency, it is vital to travel on tyres with the correct air pressure.
  • Improved Tyre Longevity – Underinflated tyres can dramatically increase wear and tear, resulting in tyres not lasting anywhere near as long as they should.
  • Decreased Chance of Blowouts – Tyre blowouts are incredibly dangerous for all road users. Not only can they lead to devastating accidents, but a blowout can also contribute to roadside debris which can cause other vehicles to have an accident by hitting it or trying to avoid it.
  • Better Handling and Performance – Under-inflated tyres can change the handling and increase the braking distance, increasing the chance of an accident.
