So right before I left my sales guy who I'll say is a pretty good guy, gives me a set a locking lugs. He said they usually run about 40 bucks and something about they where left in a vehicle or something so he grabbed them. Anyway he was telling that for a while people where getting their spare tires stolen off the back of their jeeps because they are not really locked down and was telling me I might want to use one on the spare even if I don't use any of the others (set of 4 of course). Is this really a big issue? I live in a very small town but I work in a larger one. If I keep the wheel on is this something I should seriously do? I guess it can't hurt right.
