With TC215 systems, you simply reset the alert levels as required.

• In standby mode, press and hold the SET button for 3 seconds. Release after the beep.
• Press the SET button repeatedly to scroll through the different settings and press the + or – buttons to adjust the setting.
• Press and hold the SET button again for three seconds to save the settings and exit the settings mode.

The new settings take immediate effect

Yes, it can, and there are a couple of options.

• If you are only monitoring the trailer tyres and not the car tyres, then just take the monitor to to the appropriate vehicle.
• If you are monitoring both car and trailer tyres, you will need one monitor for each car. You can then register the trailer tyres to both monitors. If it is a TC215B system, you only need to press LINK- to stop monitoring the trailer or LINK+ to start monitoring it.

With TC215 system: Just press the 'LINK' button when you connect or disconnect. This allows you to start or stop monitoring the trailer tyres. When unlinked, the trailer tyres are not shown on the monitor. If used with multiple trailers, a smart transceiver can be fitted to each trailer to simplify switching trailers.

Heat is transferred from the tyre through the metal of the wheel, and the system is sufficiently sensitive to measure the change as the tyres come up to normal operating temperatures, which is always several degrees above ambient.

As the seasons change, it is useful to know the tyre temperature. In cold weather, you need to have more air in the tyres the get them to the correct working pressure.

Temperature measurement is extremely useful for detecting problems with wheel bearings or with brakes binding. this can lead to tyre fires or to expensive bearing damage. Some HGV users have installed our systems primarily to give warning of overheating because they can't afford the risk of a tyre fire.

TyrePal systems communicate at 433.92 MHz, and comply with strict international requirements about causing and accepting radio interference. All devices using radio frequency signals are subject to loss of signal from time to time and this may be more marked in certain areas, especially around military or communications installations.  TyrePal systems are optimised to overcome interference as far as possible or to minimise its impact, while providing acceptable battery life.  A TyrePal sensor measures the pressure and temperature of the tyre every few seconds, while it is in motion, but unless the pressure is actually falling, a signal is transmitted to the monitor very briefly only every five or six minutes. (The exact timing varies from model to model). This is done to reduce power consumption. In the event of falling pressure, the signal is transmitted immediately and is repeated every few seconds.

The monitor displays the latest reading it has received, so if several signals are not received due to interference, it merely means that the pressure displayed is not updated for a few cycles. In the event of falling pressure, repeated transmission means that a warning will still be given within half a minute or so.

If the monitor does not receive signals from a sensor for an extended period, it displays an alert for that tyre position. The exact period before this alert is given depends on the model.

For large vehicles or trailers where the transmission distance is greater than about 7m from the furthest sensor to the monitor, we recommend the use of a signal booster or repeater. This is typically positioned at the front of a trailer, where it can re-transmit the signal from the tyre sensors, or in the case of a motorhome towing a car, at the rear of the motorhome. No configuration is required – it simply picks up the signal and re-transmits it automatically.

This is not really practical and the simplest way to use a single monitor on two vehicles is to switch the sensors from one vehicle to another.

The reason is because when you register additional sensors, the new sensor replaces any existing sensor in the same location. On systems designed to monitor more than four wheels, you can register additional sensors to new positions, but if you use this for two different vehicles, you will get ‘no-signal’ error messages from the vehicle that is not in use.

Not really.  Sensors can be locked in position so that they require a tool to remove them. This prevents casual theft.

TyrePal Solar and TC215 sensors have a brass thread which is very resistant to corrosion when used on normal tyre valves with a brass thread.

Corrosion occurs mostly where different metals are in contact in the presence of an electrolyte like salty water.  Some specialised tyre valve stems are made of aluminium. We do not recommend using the system with this type of valve as corrosion will occur where the different metals are in contact.

If the monitor does not receive signals from a sensor for an extended period, it displays an alert for that tyre position. The exact period before this alert is given depends on the model.

• Put a small amount of WD40 or silicone grease on the locking ring and on the threads of the valve stem. This film separates the different metals.
• Remove the sensors once a month during winter to prevent bonding.
• Remove the sensors if the vehicle is to be unused for several months.
• Do not use the locking rings if the vehicle is being used in extremely salty conditions, such as a boat trailer where the wheels may be immersed in the sea.

TC215B/Solar Systems
The sensors are supplied with a hex nut that, when tightened against the back of the sensor, acts as a locking nut to prevent removal of the sensors. A tool is provided with each complete kit to facilitate this.
TC215E - heavy duty
The standard sensor, TCSE has an integral shroud that rotates freely over the sensor so it can only be fitted or removed with the supplied tool. The shroud can be removed if not required.
TC215F
Flow-through sensors are secured by locking nuts.

TyrePal can supply systems with either external or internal sensors.

External sensors
External sensors are generally better for DIY fitting to existing vehicles.

• Much easier to install, as the tyres don't need to be removed
• Batteries are easily replaced and are readily available
• Can be quickly switched between wheels. This is very useful for track use or for transferring between summer and winter tyres
• Can be tested by the user very easily by switching them between tyres
• Sensors can easily be replaced if necessary

TyrePal external sensors are designed to withstand all kinds of adverse conditions and have been rigorously tested, including extended life salt spray corrosion testing.

Internal sensors
Internal sensors are more appropriate for OEM applications.

• Can be supplied pre-installed in wheel-tyre assemblies.
• No exposed parts - completely protected against physical damage
• Sensor battery is non-replaceable, but life can be matched to the service life of the tyres.
• For retrofit, the tyre must be removed for installation

Yes, for most systems, just go to the product page and you will see additional sensors listed. These can be registered for any tyre position.

TC215B/Solar 6
The sensors for the TC215B and Solar 6 are 21mm diameter x 17mm long. They weigh approx. 10g.
The sensors for the Solar Colour are 18mm diameter x 13mm long. They weigh approx. 6g.
This is within the tolerance for most wheel balancing, so rebalancing after they are fitted is not usually necessary

Batteries for the sensors are flat lithium cells, widely available, and you can order them here.
TCSO and TCSN-3  sensors use CR1632 batteries
TCSU sensors (for the Solar 4) are fitted with CR1225 batteries

They should last at least around 18 months. Replacing them only takes a few moments, just unscrew the outer cover from the sensor, slip the new battery into place (ensuring it is inserted with text side up) and replace the cover.  The battery tool provided in the kit can be used to assist.  As you replace the cover, take care that the rubber o-ring is correctly seated, is in good condition and only one o-ring fitted.

Yes, but of course, you can check the tyre pressures with the monitor, so it is only necessary when air needs to be added or removed.

For heavy vehicles, we can supply systems that don't need the tyres to be removed. These use air through sensors or sensors that fit inside the tyres.

Yes, spares and tools are included in the kit.  The battery tool is required to assist battery fitting/changing, and the hex wrench is provided for tightening the valve stem locking nut, giving security from casual theft.

Yes, and TyrePal systems really are very quick to install. There’s no wiring and no need to remove the tyres. The procedure is different for each model, so please refer to the instructions for detail.

For Solar systems, just screw the sensors onto the appropriate tyre valves and the monitor immediately displays the tyre pressures. You can then set alert levels as required.

TC215 systems can have sensors registered to any of 22 wheel positions, so you need to register the sensors prior to use.  Once sensors are registered, the display only shows data from the registered positions.

We can currently supply systems to all EU countries.  When you order on line you will be asked for the country where the goods are to be sent. The appropriate shipping and VAT (tax) options are then presented to you.

Unfortunately we cannot supply outside of the EU at this time.

Solar
A re-usable sticky pad is provided for mounting the monitor. Just place the sticky pad on a clean flat surface and position the monitor on top. Choose a position where it can be seen by the driver without interrupting the view of the road.  For security, it can be removed and hidden while the vehicle is unattended.

TC215
The TC215 is supplied with a robust windscreen mount with suction pad. Some models may also include a free-standing mount and a screw mount for permanent fixing.

Please see individual product specifications for detail.

Yes! Our sensors have been actively tested at speeds up to 300km/hr. TyrePal systems are frequently used for high performance cars such as Ferrari, Porsche and Aston Martin for track and race applications where high speeds are the norm.

Almost certainly! Systems can be configured for practically any vehicle with pneumatic tyres.

There must be room for the sensors to be screwed on to the tyre valves. Sensors are approximately 20mm diameter and 20mm long and ideally, should not protrude much beyond the tyre profile when fitted. In some cases, it may be desirable to fit shorter valve stems.

Please also check the maximum tyre pressure.  Most cars and motor-homes can use the standard version, which cater for pressures up to 99psi. For higher pressures, typically on heavier vehicles use the TC215 truck and bus system (max 188psi)

Yes. The backlight turns on automatically when it gets dark and if the vehicle is in motion. It turns off when it is light or when the monitor is in sleep mode. Press any button to turn the backlight on manually.

This is normal.  The monitor and sensors go into a sleep mode to conserve battery power when the vehicle is stationary. After a few minutes of driving, the system updates fully and shows the current tyre pressures.

If the monitor does not receive a signal from a sensor for some time, the display for that particular sensor goes blank. If this occurs while the vehicle is moving, there is a problem receiving the signal from that tyre which can sometimes be caused by temporary interference from surrounding radio signals.

For general motoring we recommend that you set your levels at 20% above the level recommended by the vehicle manufacturer and 15% below the recommended level. For example, if your vehicle has recommended “normal” tyre pressures of 35psi front and 40psi rear, you would set your front “high pressure” level at 42psi, rear at 48psi, and the front “low pressure” level at 30psi and rear at 34psi.

For temperature setting, we recommend using the factory pre-set of 70C. This is high enough to avoid spurious alerts in normal driving and low enough to give an alert in the event of a tyre overheating.

Track and race users are trying to squeeze optimum performance from the vehicle so tend to set closer tolerances, whereas other users may prefer to avoid nuisance alarms and be content to just have a warning if things are going wrong.

No. Our systems are powered by an internal rechargeable battery.

A full charge takes 2.5 hours and provides about 28 hours operation, or four weeks driving at one hour per day. It is not harmed by partial charging and does not have to be fully discharged before recharging. If the power is low, a battery warning icon will appear. It should be charged using the supplied lead, or will charge automatically via the solar panel on our Solar systems

The TC215 system can be permanently wired if required and TC215 heavy duty systems are supplied with a fused connector for this purpose.

In standby mode, press and hold the SET button (marked with a spanner icon on the Solar models) for 3 seconds. Release after the beep. Press the SET button repeatedly to scroll through the different settings and press the + or – buttons to adjust the setting.

For further information please refer to the user manual.

TCSE External sensors: 19g
TCSF Flow through sensors: 23g
TCSI Internal sensors: 33g

The TCSF heavy-duty sensors are intended for commercial vehicles, buses etc. for which wheel balancing is not required.

These heavy-duty sensors are not normally used on cars, light vans and light trailers, but if they are, the wheels will need to be re-balanced.  For these applications we normally recommend the TC215B system which uses smaller and lighter sensors. The TCSO sensors weigh only 10g with batteries, so wheel balancing is not normally required.

The high temperature alert can be left at the factory default for most users.

This temperature will not be reached in normal operation, but will be reached if a sidewall is overstressed and in danger of a blowout or fire. It may also be reached if the wheel is overheating due to brakes binding or a wheel bearing problem.

Please note that the sensor is not measuring tyre tread temperature to enable performance to be optimised for a particular tyre rubber compound. It is measuring the temperature of the sensor located on the valve stem, which could be higher or lower than the tread temperature. The sensor is reasonably well thermally connected to the tyre, and this is sufficiently sensitive to give alerts when needed.
