I'm thinking of buying a set of used 15x10 rims but they have been drilled for screws and I dont us them.I have been told that where the holes are it wouldn't matter.and that they wouldn't cause a problem. I've also been told that the holes could be filled and filed down for very little money. Anybody ever run slicks tubeless with rims previously drilled for screws and a inner tube. did it leak or would it be a problem passing tech at the track.
