Peterbilt Motors Co. is now offering a four-channel version of Dana Spicer's Tire Pressure Control System (TPCS) as an option on its Model 367, providing each tire with an independent inflation/deflation valve. Consequently, loss of air to one of the drive tires — in the event of a tire puncture, for example — will not disable the vehicle.
Vocational customers, particularly in mixer, rescue, dump and logging applications, spec TPCS so that operators can increase and decrease air pressure in the tires using an in-dash console, thus adjusting traction to best meet application and surface conditions, Peterbilt says.
Operators can adjust tire pressure for loaded and unloaded applications, as well as for on-highway, off-highway and emergency surface conditions. When the vehicle returns to normal paved road speeds, TPCS automatically increases tire pressure to prevent excessive tire wear.
