Tire Valve Stem Caps!
Anyway, I took them off and put the black plastic on and no more problems. Except, I hate the way they look. I really wanted something to standout so I found these (walmart I think). I took out the plastic that was lining the inside and force fitted them over the black plastic caps. Love the way they look against the silver and my diamond visions which have a blue tint as some of you know...
