Double Seal Tire Valve Stem Issue

[swampgator352]

We recently had a tire issue while on the road that was repaired by a truck tire company and involved replacing the tire valve stem. The technician replaced our valve stem with what I think is a double seal valve stem. When we got home, I added air to my preferred PSI and installed an external Tire Pressure Monitor. Several weeks later I notice the tire pressure is a little bit low, but when I remove the TPMS sensor I find that I am unable to get a reading with a manual pressure gauge (i.e. the gauge does not show anything) and my TPMS still shows a the slightly low reading...not that the sensor was removed. While I was driving around town, the sensor does fluctuate slightly.

I'm a bit stumped. Any thoughts on how I can check the pressure on this tire?

What other vehicle or tire have you tried the gauge and tpms on on?

Ended up taking it in to a tire shop, they concluded that the last tire guy must not have put in high pressure valve stems and that the valve stem was about to burst. They replaced the valve stem this morning...so far so good.

I was in the truck tire business back in the 70’s and 80’s. Never heard of a high pressure valve stem. A Schrader valve seem is a Schrader valve stem. Now there is a difference in a valve body. Can’t imagine a truck tire center would use an incorrect valve.

Sounds like cheap rubber valve stems vs all metal stems. Had that problem years ago with a class C the air always was tough to keep topped to the correct PSI. Replaced tires and changed to metal stems, no more problems.
