The set-up is straightforward. Robust sensors fit into a bracket that straddles two wheel nuts, with a pair of brackets per wheel – each manufactured from a mild steel with a zinc nickel coating, for maximum durability and minimum weight. They are suitable for fitment to both steel and alloy rims. If a nut starts to loosen, a signal is instantly transmitted to the in-cab receiver, alerting the driver to the problem.

Our detection system is unlike anything else on the market and is revolutionising how the commercial vehicle industry protects itself against the dangers of wheel loss.

What’s more, the latest generation Wheely-Safe system is telematics-ready, meaning alerts can also be sent back to the transport office or workshop, as well as to the driver.

There are many reasons why a wheel may come off a moving commercial vehicle. A Transport Research Laboratory report suggested the standard design of wheel fixings – typically a heavy vehicle will use eight or 10 sets of studs and nuts per wheel – requires a thorough maintenance regime to adequately reduce the risk of detachment. However, even the best-maintained fleets can still be susceptible to issues beyond their control.

Whilst most operators follow the basic routines and schedules of maintenance, even with the best procedures in place you can still risk losing a wheel because a nut and bolt is a mechanical solution that has its flaws. When tightening wheel nuts, you have to create enough friction to keep it on, but you have to allow the wheel to go on and off, so you have to have clearance around all the holes and that allows for micromovement. Micromovement allows for things to start working loose. Put simply, a nut is a mechanically deficient way of doing things, but it isn’t going anywhere soon!

Our external TPMS sensors are quick and easy to fit – they screw on to replace the valve cap and pair automatically with the in-cab receiver, for a complete wire-free set-up.

For fleets selecting our internal TPMS sensors, they adhere to the rim of any size wheel, can be easily installed by workshop staff or your local tyre dealer, being manufactured from a flexible engineering-grade material.

All sensors are fully sealed for maximum durability and protection from the elements, and offer a battery life of 3-5 years (external) or 5-10 years (internal), depending on usage and application. Sensors can be replaced at any stage during the life of the vehicle.

Battery life is optimised thanks to an accelerometer which wakes the sensor for every journey, allowing a low-power ‘overnight’ or ‘weekend’ mode to commence when the vehicle is stationary, given that most underinflation occurs with slow leakage over time.

Precise tyre pressure readings can be taken at any time using a handheld Pressure & Brake Temperature Checker. Simply hold the handheld device close to the sensor for an instant pressure reading in psi or Bar. Alternatively, our separate WalkAround Checker is also ideal for drivers, and uses colour coded red, amber and green signals to alert a driver should maintenance be required.

Fitting our TPMS sensor technology will help you run your fleet more efficiently. An amber ‘maintenance alert’ will flash on the receiver every three seconds whilst the vehicle is in overnight mode, should the pressure in one or more tyres drop by between 15% to 25%.

A red ‘critical alert’ will flash, and one bleep will sound every two seconds for two minutes, should the pressure in one or more tyres drop by 25% or more, or in the event fast leakage of at least 2 psi per minute is detected – warning the driver to pull over safely.

If the air temperature inside a tyre exceeds 100°C, often the sign of an impending blowout, a red temperature alert will flash every two seconds whilst in journey mode, and one bleep will sound every two seconds for two minutes. This will alert the driver to pull over safely, before a potentially dangerous tyre failure occurs.

TPMS alerts include:

• ‘Maintenance’ low pressure warnings (-15% to -25%)
• Critical low pressure warnings (-25%+)
• Fast leakage
• Early high temperature warnings (85°C to 100°C)
• Critical high temperature warnings (100°C+)
• ‘Maintenance’ sensor low battery

This handheld tool is the perfect way to speed up fleet inspections for workshop staff, providing access to instant tyre pressure readings in either Bar or PSI when held next to any Wheely-Safe TPMS sensor.

The Pressure and Brake Temperature Checker provides accurate readings from the TPMS sensors without the hassle of connecting a pressure gauge to the valve, which removes air and is unhygienic – speeding up the time taken to conduct fleet checks and safety inspections.

Additional functions include reporting the highest and lowest brake/hub temperatures recorded in the last 24 hours, when held against any brake temperature sensor.

You can purchase as many Pressure and Brake Temperature Checkers as required – some fleets prefer to keep one in each vehicle, whilst others supply one to all technicians.

Our keyring-mounted WalkAround Checker is designed to support a driver’s daily inspections. They take pressure readings from any Wheely-Safe sensor, providing an immediate green, amber or red alert, to advise the driver whether a tyre is correctly inflated, in need of a top-up at the next workshop visit, or unsafe to operate in the current condition. They also record the walkaround activity to ensure this vital activity occurs regularly.

Plus, they monitor our brake/hub temperature sensors, alerting the driver if abnormally high temperatures have been recorded in the last 24 hours.

For longer vehicles, we offer both wired and five-year battery-powered dipole antenna boosters, for excellent receipt and amplification of the signals from sensors on the rearmost axles to ensure the receiver in the cab never misses a transmission. When discussing your requirements, we can advise if a booster might be needed.

Additional sensors can be purchased at any time to support the running of your fleet, such as in the event of a vehicle being involved in an incident. And because Wheely-Safe features auto-pairing as standard, just fit the new sensor in position, and it will automatically be picked up by the receiver. It really is as simple as that!

We can supply you with everything you need for installing our TPMS sensors on vehicles with twin wheels on an axle, ensuring it is easy to take pressure readings from the inner wheel on twin fitments.

Choose from our solar or wired receiver, positioned in the cab to provide instant audible and visual driver alerts.

An external TPMS sensor replaces the valve cap on each tyre. For inner wheels, we can supply valve extensions. Internal TPMS sensors can also be specified upon request, for fitment onto the wheel rim by a qualified tyre technician.

Each outer facing wheel is fitted with a wheel loss sensor, placed inside a bracket that straddles two wheel nuts. Two sensors and two brackets are required per wheel, mounted opposite each other. The wheel loss sensor double up to also monitor temperatures around the brake and hub.

For longer vehicles, the choice of either a five-year battery-powered booster, or wired booster, is mounted on the chassis to boost the signal from TPMS and wheel loss sensors on the rearmost axles.

For fleets looking to connect the Wheely-Safe system to their on-board telematics or CAN bus, we can supply a range of suitable telecan ‘black boxes’.

We recommend issuing drivers with a keyring-mounted WalkAround Checker, for reading signals from our TPMS and wheel loss sensors during their daily walkaround inspections.

Our handheld Pressure and Brake Temperature Checker enables drivers and/or technicians to take accurate readings from any of our TPMS or wheel loss sensors.
