Did you know that both under- or over-inflated tires decrease the tire’s mileage up to 15% (approximately 30,000 km)?*

Did you know that the explosion of a tire – which is being inflated after run-flat damage – surges into the surrounding area at violent speed and with a force equivalent to 12 tons? It has the same impact as a truck hitting you!

(*assumptions: 30 liters per 100km, tire lifetime of 200,000km, 20% over-inflation or 20% under-inflation)

To minimize these risks and costs, we have the optimal solution for you:
IVTM, the Integrated Vehicle Tire Pressure Monitoring system

How can IVTM improve your business?

• Helps preventing tire blow-outs, accidents and damages to other road users, by timely informing the truck driver of a leak before the tire goes flat and is destroyed
• Reduces the fuel consumption and increases the lifetime of the tires, by automatically informing the driver in his cabin when the tires are under-inflated or over-inflated,
• Remotely monitors tire pressure (in combination with TrailerGUARD™ telematics, a function of the Intelligent Trailer Program) and enables the fleet manager to support the driver or dispatch a service team
• Helps preventing an explosion during the inflating of a truck tire which has previously suffered run-flat damage.

With the Return on Investment Calculator, you can quantify how much money you can save by installing IVTM

• IVTM monitors the tire pressure on all operating wheels
• IVTM warns the driver when any of the tires are under-inflated or when there is a tire leak
• In combination with TrailerGUARD telematics, IVTM will also report the tire pressures on the web portal and warn the fleet manager or dispatcher via SMS or e-mail

How does it work?

INSTALLATION

• Each wheel is equipped with a wheel module which includes a pressure sensor and a wireless transmitter to monitor the tire pressure on all wheels
• In the IVTM system setup menu, each module is identified and manually allocated to the wheel on which it is mounted
• The end-of-line test confirms the values of all tires and the correct functioning of the complete installation

OPERATION

• The system is automatically activated when the truck ignition is turned on
• A special sensor in the wheel module checks the tire pressure, and sends the information wirelessly to the IVTM control unit (ECU, one on the truck or the bus, and one on the trailer) with a secured radio frequency channel
• The control unit identifies over-inflation, under-inflation, and changing tire pressure, and distinguishes whether decreasing pressure is caused by a tire leak, or comes from normal pressure variations
• The trailer control unit sends the pressures via the CAN line* or wireless to the truck control unit (ECU). If TrailerGUARD Telematics is installed on the trailer, the pressure of each tire is also sent to the Telematics webportal via GPRS. (*Trailer CAN communication works only if a WABCO Trailer-EBS is installed)
• In case of a tire leak, the trailer control unit sends an immediate alert to the truck or to the Telematics system.
• The truck ECU sends all the tire pressures from the truck and the trailer to a separate WABCO display or to the truck/bus dashboard in the cabin…
• The fleet dispatcher can contact the truck driver to alert him of a tire pressure, and dispatch a service partner.
• When the tire has become flat, WABCO strongly recommends not to recharge it to avoid a tire explosion

SERVICING

• The IVTM wheel modules can be demounted to exchange a wheel rim or a tire
• If each IVTM wheel module is remounted in the same place on the vehicle, there is no system re-configuration required

WABCO introduced its IVTM system as the commercial vehicle industry’s first tire monitoring system in 2003 in partnership with Michelin. IVTM is a trademark of Michelin.
