Low Tire Pressure?

Due to setting up my Tire Minder system incorrectly I decided to clear it and start all over once I got the CG that we are at now. Saturday morning I set all of the air pressures on the tires and programmed the set pressures. This morning while it was cool I started to install the tire sensors. Everything was going OK until I come across one of my rear inside tires with only 40 pounds of pressure. My MH has been sitting in the same spot since Thursday, so I could not have hit anything to damage the tire. When I set everything on Saturdays it has been sitting here for a day and half.
I re-aired up the tire and installed my sensors. My plan is to check it several times today and tomorrow to see if the pressure drops again. If it goes low again I will call either Good Sam or CoachNet (I have both for right now).

Any ideas what would cause the tire to loose half of its pressure? My wife mention that do I think that a sore loser at the Saints/Bucs game would have let the air out. I mentioned that this option would be the best being all I had to do was re-air the tire. But I do not expect that to be the case being we are at Lazy Day's CG and directly beside the main building.

Sounds like you pulled the sensors off the tires?? If so, the Schrader valve in your valve stem didn't set completely and had a slow leak. Whenever I pull a sensor or valve cap, I use to the spit test to see if I have a bubble at the stem (slow leak).

Or if you have your tires balanced with Equal or beads, something may be stuck in the valve. I did essentially the same yesterday only I put the sensor on and the tire was flat (on toad) a couple of hours later. Guess I know where the 'spare' gasket I found goes now!😚

I checked my pressure a little while ago and the pressure is holding. So it must be that I loosened the valve stem and when I reset the sensor it tightened back up.

I will start doing the "spit" test from now on plus get a valve stem tool.

The spit test is second nature to me now.
