What is the difference between TPMS and ATIS?

In Episode 1 of Pressure On, Marcus Cornwell of Celerity DRS talks us through the differences between a traditional TMPS and a more proactive Automatic Tyre Inflation System.

A TPMS uses a sensor mounted in the wheel to measure air pressure in each tire, and when air pressure drops below the manufacturer’s recommended level, the sensor transmits that information to the vehicle’s computer system and triggers a dashboard indicator light or notification.

Although the driver is given a warning about the loss of tyre pressure, unfortunately the problem is still there and the driver will have to stop the vehicle, check for damage to the tyre and potentially have to call for roadside assistance. Alternatively, they may ignore the warning and continue on their journey. This may lead to a blowout, further damage to the vehicle and potentially put their own life (and other road users’) lives at risk.

This type of situation is where an Automatic Tyre Inflation System really starts to shine!

An Automatic Tyre Inflation System (ATIS) not only monitors the tyre pressure and updates the driver to any change in pressure, but the system will automatically re-inflate the tyre to maintain the optimum pressure.

An ATIS not only monitors the tyre pressure and updates the driver to any change in pressure, but the system will automatically re-inflate the tyre to maintain the optimum pressure – even if the tyre has been punctured and while the vehicle is still moving. In the event of a puncture, this would allow the vehicle to continue towards its destination, allowing the driver to get home safely or meet their delivery deadlines – all without the cost and downtime associated with roadside assistance and the repair or replacement of a tyre.

Automatic Tyre Inflation Systems also significantly reduce the chance of a blowout and the potentially dangerous consequences we associate with them i.e. damage to the trailer and debris flying off and hitting other road users – dangerous stuff!
