Kenworth announced that its T680 and T880 models are now available with the fuel-saving SmarTire tire pressure monitoring system (TPMS) by Bendix CVS as an option.

The factory-installed Bendix system uses wheel-mounted sensors in each tire to monitor the tire’s pressure and temperature. Sensors are located on the steer and drive axle wheels. If tire pressure becomes too low, or tire temperature becomes too high, the system sends a signal to the driver via the dash display.

“Fleets and truck operators are becoming more proactive in addressing tire inflation as they strive to maximize each truck’s fuel efficiency,” said Kurt Swihart, Kenworth marketing director. “Now, with the Bendix system for the T680 and T880, they can take advantage of an easier, very efficient and time-saving way to regularly monitor tire pressure and temperature and gain enhanced tire life. The result can be less downtime and more money in their pocket.”

 According to Bendix, a tire that is under-inflated by as little as 10% can result in a 1.5% drop in fuel economy, which may increase fuel spending by up to $1,000 per year for a single truck. Under-inflation by 20% results in a 30% reduction in tire life.
