I have had this problem on my 2007 500 for a couple of years. Apparently the corrosion spots that show up on rim, eat into the bead, allowing air to leak out. I had the dealer dismount the tires and clean up the corrosion, which lasted for about a year. The problem is back. Has anyone come up with a permanent fix for this(other than new rims)?

 

A lot depends on where you live and drive, but something that might be getting overlooked.
What are you using to clean the wheels and tires.? Could there be something there that is accelerating corrosion?
Most of the time a coat of paint/sealer on the inside edge of the rim usually stops that.

 

yes paint sealer (Polyurethane) will work so will clear fingernail polish after its all cleaned on seal that will stop corrosion
