I just picked up some C5's today and I noticed that there were little cracks in the rims. Not just one of them, but a couple on all four.

The cracks are appearing where the spoke meets the outer dish part of the rim. I was wondering if this was normal wear and tear or is it something serious, and if I took it in to a wheel shop, would they be able to fix something like that? I'll have pics up soon to show what I'm talking about. Hopefully it won't be too much of a problem. Thanks in advance.
