TYRE TORQUE

Establishing your own tyre-monitoring programme is now a realistic option thanks to TYREDOG

For many vehicle owners, selecting a new set of tyres is considered to be what marketers call a “grudge” purchase. Seldom does the average buyer seem to enjoy discussing the merits of different brands and tread patterns, the technology behind the tyre development and the potential for reducing total operating costs by adopting a low rolling-resistance tyre compound.

Several of the prestige car brands offer tyre pressure monitoring systems that advise when pressure or temperatures vary, indicating a possible puncture or incorrect inflation pressure. But, for many vehicle owners, the regular checking of tyre pressures is often left to the dealership as being part of a regular service check item.Tyre-Dog_P4

As vehicle technology has advanced, so too have the recommended service intervals, extending from the common 10,000 km schedules out in some examples to 60,000 km and beyond. Obviously, more than ever, there’s a need for every driver to monitor the pressure and condition of their tyres, and with Chain of Responsibility requirements now dominating fleet management, that means someone, usually the driver, has to assume individual responsibility.

That’s where TYREDOG comes to the aid of even the most non-technical driver. It’s a three-minute job to swap the valve caps on each tyre for a TYREDOG pressure sensor. Just unscrew the old and replace it with the new cap, with each sensor containing its own small lithium battery power source.

The sensor communicates with a receiver mounted in the vehicle, usually fitted on the interior of the windscreen by suction cup, providing the current tyre pressure to an accuracy of +/- 1 psi. It also provides tyre temperature measurement to an accuracy level of +/- 2 degrees C.

The information is displayed on the screen of the data recorder monitor unit in a schematic layout that shows each individual tyre fitment position, temperature and pressure. The monitor unit itself is powered either by a cable link to a 12-volt socket or by two AAA batteries contained in the unit, thereby removing the need for an external power source.

When attaching the sensor caps for the first time it’s just a matter of inflating each tyre to the correct recommended pressure, slipping the supplied battery into the sensor cap and screwing on the valve stem, in the same way as when fitting a conventional valve cap. The LCD monitor then displays the pressure monitored by that sensor cap in the digital display.

The information shown on the LCD monitor not only includes the tyre pressures and temperatures, with alerts for anomalies, it also shows the battery condition of the sensors and the monitor unit itself.

Although the TYREDOG unit evaluated by Delivery was for the monitoring of four tyres, specific units are available for medium and heavy trucks, up to a maximum of 34 sensors monitored by one unit and suitable for B-double application.
