Ok, an update. It’s only 15 degrees F out there right now but I had to get out there and check some things out based on some of your input.
Of my four wheels on the RV 3 had the TPMS sensors on them, one did not. The one that did not have a sensor on it was still aired up to 118 lbs. I removed this sensor a few weeks ago because the air pressure was low, around 80 lbs. I aired up the tire to 120 lbs and left to celebrate Thanksgiving with our daughter in the Detroit area. Came back and never checked the tire to see if it was holding air pressure.
My suspicions are that the TPMS sensors are leaking air because the temperatures outside are very cold. All the sensors held air pressure all summer long with no problems. I just got done airing up all four RV tires to 120 lbs and we’ll see what they read out at tomorrow.
If it’s the TPMS sensors leaking I will try wrapping the valve stem with a little Teflon tape to see if they hold air.
Stay tune, I’ll report back tomorrow.
Again, thanks for all your input and suggestions.
