MICHELIN Wheel Security & TPMS Heavy Fleet


MICHELIN Wheel Security & TPMS Heavy Fleet takes a fresh approach to tackling wheel loss, compared with systems such as simple indicator tags, more complex full rim indicators and special wheel lock nut systems. Given these solutions have not eradicated the issue of wheel loss from the industry, we focused on developing a technology which detects the in-motion onset of wheel loss prior to detachment.

Our solution is miniature and robust, providing an in-motion alert to the driver after approximately one turn of adjacent wheel nuts (1mm of movement). It straddles two wheel nuts and is held in place with a bracket. When the wheel nuts start to work loose, the switch opens, and a radio frequency alert is immediately sent to the display unit in the cab, warning the driver of imminent danger. It can also be linked with telematics systems to provide alerts to the transport office or workshop team as soon as a loosening wheel is detected.

The wheel loss sensor comprises a fully sealed electronic/radio unit and a sealed switch coupled with a plated mild steel bracket (zinc nickel coated for maximum corrosion resistance). Alloy wheel rims can be accommodated also with prior notification. We recommend fitting two sensors to each axle end, and for balance, fitting them opposite each other.

MICHELIN Wheel Security & TPMS Heavy Fleet also communicates with a receiver in the cab in the same way that traditional Tyre Pressure Management Systems connect, so we’ve combined these functions to deliver a fully integrated in-motion driver alert package consisting of a TPMS, patented wheel loss system and brake/hub temperature alert system too.

After five years of development, today’s product is a fully patented solution. Extensive testing has shown MICHELIN Wheel Security & TPMS Heavy Fleet does exactly what we aimed for – an in-motion alert to the driver after approximately one turn of adjacent wheel nuts. The sensor has passed extensive laboratory and field testing, including successfully running across several fleet operators and manufacturer vehicles prior to its launch.

Crucially, this means for the first time that a driver will receive an alert the instant a potential wheel loss issue is detected – no matter what speed they are travelling, or in what weather conditions – allowing them to pull over safely.

Due to its location next to the wheel rim and braking mechanism, our onboard heat sensor is also perfectly positioned to send alerts to the cab if a brake issue is detected. Temperatures exceeding 100°C often indicate maintenance issues such as sticking brakes or hub failure.

By monitoring the maximum and minimum temperatures of each sensor, any unusual braking temperature patterns can be spotted early. For example, sticking brakes will result in the sensor detecting higher temperatures, whilst ineffective brakes will show little or no temperature rise. This additional feature is invaluable for brake management, and helps to reduce a major cause of commercial vehicle fires, downtime and accidents.

The MICHELIN Wheel Security & TPMS Heavy Fleet sensors incorporate some clever twists, to achieve an intelligent but small and ultra-durable sensor. Key features:

  • robust, waterproof and resistant to temperatures of 125°C
  • suitable for commercial vehicle tyres inflated to a maximum of 188psi
  • compact design (diameter of 25.3mm, height of 22.6mm)
  • auto-pairs with the receiver on each journey
  • if fitted to a trailer will pair with a new truck seamlessly
  • no need to input pressures into the receiver – the sensors auto-calibrate provided tyres are correctly inflated prior to fitting when cold
  • two LEDs mounted around circumference to indicate the sensor in distress
  • an accelerometer to wake up the sensor on a new journey, allowing for low power sleep mode when the vehicle is stationary. Hall Effect Sensor and NFC (Near-field communications) allow for instant downloading of sensor pressure and battery levels.
  • low power / long battery life design as no need for sending regular tyre pressure data
  • fully sealed unit with no battery changing required – anticipated 3-5 year lifespan, depending on usage and application
  • supplied with an anti-theft lock nut and accompanying spanner
  • no programming required

The display unit provides:

  • an early low-pressure warning via a flashing icon every 20 seconds if a tyre becomes under-inflated by 20 per cent or over-inflated by 25 per cent
  • an audible alert is added when the pressure either drops by 30 per cent, or should the tyre be over-inflated by 35 per cent or more
  • for fast leakage (at least 2 psi per minute), all icons flash in addition to a beeping alarm, alerting the driver to pull over
  • tyre temperature sensor set at 100°C.

MICHELIN Wheel Security & TPMS Heavy Fleet can be supplied with a contactless tyre pressure checker for use by the driver during daily walkaround inspections. The pressure checker is a pocket-sized device capable of giving a digital pressure reading when placing the device close to the sensor. The same device will also provide the maximum temperature reached in the last 24 hours in the hub area when checked against the wheel loss sensor.

The pressure checkers are compatible with all Wheely-Safe sensors, meaning a fleet manager, technician or tyre fitter can complete a pressure check across multiple vehicles using the same device.

Just imagine the time and cost-saving! What’s more, no more air loss every time you take a pressure reading.

Development partners

MICHELIN Wheel Security & TPMS Heavy Fleet has been developed in close consultation with specialists ranging from large global vehicle manufacturers to a number of major transport groups. These development partners have been invaluable in providing feedback for all the varying installation and application needs – as have our supplier partners Michelin and Tructyre.

How long does it take to fit?

This is dependent on how many tyres and axles are to be protected. As with the MICHELIN TPMS Light Fleet system, the components are very easy to fit and no programming is required.

How long is the warranty?

MICHELIN Wheel Security & TPMS Heavy Fleet comes with a 12-month warranty, effective from the date of purchase.

What do I do if I have a technical issue?

Please contact us via for prompt technical assistance.

Can it be fitted to cars and light commercial vehicles?

We would recommend fitting the MICHELIN TPMS Light Fleet system.


Which telematics systems is it compatible with?

It is compatible with all telematics systems.

Do I need to fit batteries?

Each wheel and valve sensor has a built-in battery projected to last 3-5 years, depending on vehicle use and applications. An accelerometer in each sensor allows it to go into low power mode when stationary for a period – for maximum battery conservation.

The pressure checker requires a pair of AAA batteries (supplied).

How do I program the correct pressure settings into the unit?

Quite simply, you don’t. We’ve designed our TPMS sensors to automatically calibrate to your tyre pressures when first installed – and they are designed to handle different pressures on different axles. This is unique to our system, avoiding the need for bulky, monitor-style receivers with fiddly buttons. Simply ensure your tyres are correctly inflated before installation when the tyres are cold.


How many sensors can the system monitor on a journey?

Up to 50 tyres can be monitored on a journey, making it perfect for operation with trailers. The system automatically stores up to two weeks of tyre and wheel incidents, including the 50 most recently paired TPMS sensors and 50 wheel sensors.

What happens if a sensor is damaged in an accident or needs replacing out of warranty?

Additional sensors can be purchased at any time.
