My Civic, Tires..skipping?

Help with my Civic! I am going to try to explain this the best that I can. When I am driving and making turns, around the corner say...and I am going not REALLY fast, but fairly fast, My tires sometimes seem like they are SKIPPING on the road. Hmm, I know that sounds odd...
My car seems like it is shaking as I make that turn, but I know it is the tires that is the cause of it. It is the Honda "rims" (if you can even call them that, the kind that you attach the Honda hub caps to). Any ideas on what it may be.
