Not a good chance of walking in and walking out with a set of wheels. Why? Most places don't keep wheels in stock, reason being it is a 1/100th chance of getting the same size by width and bolt pattern of the customers wheels. If you wanted used, then that is different, there might be a few stores around you that sales used but still it is a hard time finding them.

Don't suggest you getting SEAR's wheels, but they can usually get them in 3-4 days I work there and that is usually the time it takes.
