Re: Matching tire pressure
The system I purchased is by TST. Each tire sensor sends the tire pressure and tire temp. to the monitor. Not exactly sure if its the temp from the wheel near the sensor or from inside the tire. It reads each tire for a few seconds then moves on to another tire. If there is any change in pressure, then sensor sends that info immediately. One problem I had is trying to get the sensorsto fit inside the wheel area. The sensor aren't small, so I had to use some valve extensions. The sensors warn for low and high pressure per tire and axel. I can get the tires to match in tire pressure, but throughout the day it changes by a pound or two like DL said. I haven't had it out on the road yet, but soon!
