I set up my Pressure Pro system this a.m. First I made sure all my tires were properly inflated. I have 2 commercial quality tire gauges and used them both. But after installing all the sensors I am getting different readings on the monitor. Some are only a one lb. difference but one is out by 3 lbs. ( 100 lb. pressure). Is that normal?
Short answer is yes. Somewhere in the PressurePro literature is the range of error for the sensors. t it is +/- 5% I have no idea what it is for your commercial gauges.
depending on road temperature, type of tire, and a host of other things, you may see a rise in pressure of 10 to 15 percent after a dozen miles or so. Again, no worries, apparently it's perfectly normal.
