Anybody ever experience an endless air leak with their wheels? I have a 96 Z28 with chrome wheels that I bought over a year ago. One wheel constantly loses air - less than 1lb a day. I have had a mechanic dismount it, clean it, and use sealer on the bead (definitely where it is). Little help. Then he put green slime sealer in. No help. Then I took it to a Goodyear dealer who stated that the wheel had a little bend in it (suspicious of this), which they charged me $25 to fix and remount. I still have the leak. Where do I go from here?
