So I am trashing the rotten (rusting apart) fancy wheels from my Ranger and putting used steel wheels on. I can't think of any reason for wheel covers, or even hub covers othere than to protect the grease cap on the front wheels from being dislodged by a piece of road debris, and that does not seem likely. So I may just run these with the bolts showing. I really don't care. It's a 2001 Ranger and I am not looking for anything stylish. Will the lug studs be more likely to rust without caps? If so, I can hit them with a light coat of paint.
