Kenworth announces the addition of the SmarTire™ Tire Pressure Monitoring System (TPMS) from Bendix® CVS as an option on select Class 8 trucks.
The SmarTire technology monitors the pressure and temperature of each tire on a commercial vehicle to provide real-time tire status information to the driver. The technology is designed to warn the driver of tire-related problems, such as low pressure and high temperatures, before they become serious issues. The system reads pressure and temperature information from inside the tire and communicates wirelessly to an on-board receiver.
“With so much riding on their truck tires, fleets are finding that they need to be more proactive in addressing tire inflation issues,” said Erik Johnson, Kenworth on-highway marketing manager. “By equipping their trucks with the SmarTire Tire Pressure Monitoring System, truck and fleet operators can help avoid fuel mileage penalties, large bills for roadside assistance and penalties during roadside inspections. They can also gain more tire life, and reduce expenses that for many truck operators are second only to fuel costs.”
According to Bendix, a tire that is under-inflated by as little as 10 percent can result in a 1.5 percent drop in fuel economy, which may increase fuel spending by up to $1,000 per year for a single truck. Under-inflation by 20 percent results in a 30 percent reduction in tire life. A tire failure on the road due to improper tire inflation can also rack up large roadside assistance charges, depending on when and where they occur.
SmarTire’s in-vehicle display will be incorporated as a gauge in the Kenworth truck dash. It will provide information including actual tire pressure tire and temperature for each wheel location, along with a deviation value which show the amount of over or under-inflation from the tires’ cold inflation pressure (CIP).
