Frequently asked questions about TireMoni® Tyre Pressure Monitoring Systems:

1) All models:

  • Please note the following when installing TireMoni:

Have the first time installation done by a profesisonal, so that your driving safety is maintained.

Sensors should be installed on suitable metal valves, so that the sensor does not protrude out of the rim contour.

When necessary (passenger cars, motorbikes), have your wheels balanced with sensors installed.

  • How does TireMoni recognize the wheel position?

Sensors are marked with their respective wheel position (FL=front left, FR=front right, RR=rear right, RL=rear left) and must be screwed onto the correct wheel (valve).

  • Do TireMoni sensors have to be calibrated?

Each TireMoni knows its corresponding sensors. Calibration or assigning the sensors to the display unit is not required.

  • What happens in case a sensor gets lost?

If a sensor needs to be replaced, there are special replacement sensors (with different coding); those must be ordered for the respective wheel position and can be learned by the TireMoni display unit in place of the lost sensor. The procedure is easy and is described in the operating manual.

  • Can my TireMoni display sensors of other TireMonis?

TireMoni only recognizes its own sensors. It is not possible to display or learn sensors of other TireMonis. In case a sensor is lost, using a 'neighbour's' sensor is not possible. (see also: What happens in case a sensor gets lost?)

  • If I have installed the sensors with anti theft protection, I can only remove them for inflating the tires by using the appropriate tool - correct?

This is correct: The tool (allen wrench or flat wrench for some serials) is required to remove the anti theft protection.
Consider however: Thanks to TireMoni you know exactly, when it is necessary to check and inflate your tyres. No more guesses...

  • What are the diameter and height of the sensors?

The sensors have a diameter of 20 mm and a height of 20 mm.

  • What is the issue with short valves and tyre contour protrusion?

In most EU countries the law requires that nothing protrudes out of the tyre contours. With their 20 mm height the sensors are longer than regular valve caps and in some cases they would protrude if screwed onto the regular valves. In those cases have your tyre shop install short valves (e.g. TR412, 33 mm in length). With some hubcaps however the holes for the valves are too small for fitting the Checkair sensor; in this case TireMoni cannot be fitted or the wheelcover needs to be changed. Your local tyre shop will advise you of the appropriate solution.

  • Which installation rules have to be followed when installing TireMoni?

The law requires that nothing protrudes out of the tyre contours. Should you notice that the Checkair sensors protrude from the tyre after screwing them onto the valve, have your tyre shop install short valves and make sure that the sensors remain inside the tyre contour. Disregarding this law automatically voids the operating license for TireMoni and tpm-systems AG disclaims any liability for consequences caused by disregarding this requirement.
In addition it is recommended that tyres should be balanced with the sensors installed.

  • What is the cost for exchanging four valves for shorter ones?

Please check with your local tyre shop. During a regular tyre replacement (only when fitting new ones) changing valves is included in the installation price. In this case the valves are replaced in any case and at that occasion short valves can be fitted just as well.

2) TireMoni TM-260:

  • Can the unused sensors in a TM-260 be switched off?

TM-260 can be configured such that either the composition (4-wheels of the tractor/car plus 2 wheels of the trailer) can be shown or that only the 4 wheels of the tractor/car are shown.
Configuration is changeable via menu keys; the procedure is described in the TM-260 manual.

  • Which sensor ID's for which wheel position?

Depending on the chosen car type sensor ID's are matched to wheel position as follows:

1) Car Type 1 (4 wheels):
Sensor 1: front left
Sensor 2: front right
Sensor 3: rear left
Sensor 4: rear right

2) Car Type 2 (6 wheels - 3 axles):
Sensor 1: front left
Sensor 2: front right
Sensor 3: middle left
Sensor 4: middle right
Sensor 5: rear left
Sensor 6: rear right

3) Car Type 3 (6 wheels - twins on rear axle):
Sensor 1:
front left
Sensor 2: front right
Sensor 3: rear left outer
Sensor 4: rear left inner
Sensor 5: rear right inner
Sensor 6: rear right outer

  • How to install TireMoni on twin wheels?

When installing TireMoni sensors on twin wheels, please make sure that for the two inner tyres a suitable valve extension is used. Plastic-extensions and pressure-less extensions are not suitable for use with TireMoni sensors.

Valve extensions must be clamped down on the rim at the sensor end. Ask your tyre dealer for suitable extensions and clamps.

3) TireMoni TM-400:

  • Follow these instructions when installing TireMoni:

Have the first time installation done by a profesisonal, so that your driving safety is maintained.

Sensors must be installed on suitable metal valves for mechanical stability at high speeds.

Have your wheels balanced with sensors installed.

Before the first ride check that sensors do not touch anything when the wheel rotates and that wheel rotates freely.
