I'm sorry to hear you have issues with your nuts. You might want to make sure there is no lubricants on them. Sometimes they will get greasy from playing with them. Are you sure your nuts are the proper size? If their too small, the hubs will not grab tight. Another thing you might want to check, the holes the nuts go in should have rings around the ends of them, or curve in on the tips. If your nuts are too long, it will not allow the curved ends to wrap around the taped side of the nut. Send a picture of your nuts and where they go into the hub caps.
