Well I have had mine on my truck for a year now. I read in my owners stuff that they will bleed off about 4 pounds a week. The left one might bleed off 4 pounds in a month maybe more. The right one bleeds off 4 pounds in about 3 to 5 days. So today I was switching from my highway Michelins to my Off road Maxxis Bighorn tires. I decided to figure out where the leak was. I filled the bag up to about 50 pounds and put soap on the connection right above the bag. Bingo, this was the one. So I pulled the tube out and found out it was not cut square so I cut it off and replaced it. I filled it up and no leak. I hope that does it.
