Undetectable Tire Leak
I use Dyna-Beads, so wheel weights aren't an issue.
I took my RV to a commercial truck tire shop. I had them remove the offending wheel and immerse it in a dunk tank. After 30 minutes of repeated dunking, they could find no air loss. This of course didn't surprise me based on what I've experienced.
I had the tire shop dismount the tire and carefully inspect the wheel. They found no defects. I told them to dismount the same wheel on the passenger side and had them swap the tires. They thought I was wasting my time, but this was a last resort. Six weeks and almost 1500 miles later, I'm happy to report that the tire is no longer losing air. I believe the suggestion of a positional tire leak was indeed correct.
Just thought I'd pass it along.
