I took my Outlaws off of my Magnum Billets and put them on my stock Rincom rims. Three will not hold air. They are all leaking along the bead right at the valve stem. There are two tiny drilled holes there where the air seems to be coming from. Seems it might be a safety valve for overinfalting the tires. I have no clue. Anyone know what this is and what should I do?
