Do my tyres cost me too much ?

A good tyre management system provides savings for you:

1. On the life of the tyres

2. On fuel consumption

3. Due to fewer problems and breakdowns

4. And especially with less staff workload

FH: "Since we installed b.Alert TPMS V2, we have had virtually no problems with our tyres anymore. At the same time we notice that the tyres are in a much better shape than before and that we have much less work to keep it that way. I am sure that this will bring cost savings. "

When should I check tyre pressures?

• According to tyre manufacturers, pressures should be checked every 2 weeks.

• In reality only 2-3% of tyres a week suffer pressure drop enough to warrant inflating

• so do I check the 95% of tyres that don’t need it? A useless work load !

• Or do I check much less than needed and watse money and take risks?

So, Which tyres should I inflate?

This is the key to working efficiently. Every week 2-3% need inflating, barely 40 tyres out of 1,800 on a fleet of 300 trailers for example. How do I know which 40?

A technical soluton is needed to identify them.

With b.Alert TPMS V2, the exact tyres that need inflating are simply identified.

To what pressure should I inflate tyres?

• Pressure depends on the temperature of the air inside the tyre
• It will be quite different between summer and winter
• It will be quite different after standing still or after driving

The correct pressure to inflate to at any particular moment is likely to be different each time. This pressure can be easily calculated if you know the temperature of the air in the tyre.

The calculation is based on knowing the correct pressure at a reference temperature, for example 15 ° C.

It is also at this temperature of 15°C that it is possible to decide if a tyres needs inflation or not.

How hot does a tyre get in the summer? An example:

• Ambient temperature 40 °C

• Air temperature near the tyre 64 °C

• Air temperature inside the tyre 106 °C

• Aire pressure inside the tyre 10 bar

But 10 bar at 106 ° C means 7.6 bar at 15 ° C, which is well below the correct pressure of 9 bar at 15 ° C. This tyre is seriously underinflated and needs inflation upto 11.8 bar!

DV : "We have known for a long time that in the summer we have to put more pressure in the tyres than in the winter in order to keep the pressures consistent. We also know that we need to put hot tyres on a higher pressure after driving. We just never knew what the right pressure was. But b.Alert has solved this for us."

Are blow outs predictable?

• A blowout starts mostly by driving an almost empty tyre. It heatens and due to deformations, at last the rubber tears apart.

• Due to a damage, the tyre heats up excessively and the rubber tears apart as it weakens due to the high  temperature

• due to a tough collison of the tyre or by driving into a sharp object an important tear evolves.

Both the first two causes are relatively long upfront detectable (at least 30 minutes). If alarmed in time, the correct measures can be taken.

AS : "We drive a lot to Southern Europe. Always long drives and very hot tyres. For yearswe are confronted with a lot of blowouts, especially on the inner wheels. They inflict an explosion of the outer tyres with a lot of collateral damage.
Since we work with b.Alert TPMS V2, we are always timely alerted."

Are you worried that brakes rub, bearings fail, brake pads crack, ... ?

Each of these problems create heat in the air outside but around the wheel and the b.Alert temperature sensor can quickly detect it.

MJ : "When we installed b.Alert TPMS V2, we got a few temperature alarms. I thought they were false alarms, but the cause was worn bearings. Luckily we got early warning, were able to intervene in time and avoid damage, costs and disruption."
