Dana Spicer’s Tire Pressure Control System (TPSC) is now available as a factory-installed option on Peterbilt's Model 357, Peterbilt Motors Co. has announced. TPSC allows the operator to match tire pressure to terrain and load conditions without leaving the cab.
Using an in-dash console, operators can activate TPCS on the go to increase and decrease air pressure in the tires, thus adjusting traction to best meet application and surface conditions. Operators can adjust tire pressure for loaded and unloaded conditions - as well as for on-highway, off-highway and emergency surface conditions - for a total of six different settings. When the vehicle returns to normal paved-road speeds, TPCS automatically increases tire pressure to prevent excessive tire wear.
"TPCS is ideal for our vocational customers who encounter highly variable terrain and load conditions, particularly those in mixer, logging and dump applications," said Peterbilt assistant gm Dan Sobic. "It helps ensure top vehicle performance when going from paved highways to rock, dirt and sandy surfaces, and back again."
