I would have the tire dismounted and checked inside for a nail or such. Sometimes they are not visible from the out side.
Totally agree. Had a very similar problem with a tire on my Wrangler. It would loose enough air over a couple of weeks to trigger the TPMS. I took it off, submerged it and never could find a leak. Continued driving with it for a few months until it finally got to the point where it wouldn't hold air overnite. This time when it was submerged there was a very small leak detected in the tread. The tire shop removed it from the rim and found a screwdriver bit that had migrated thru the tread all the way to the inside.
