I would think finding the rims would be as easy as going to the local tire shop and picking out what style you like, the size seems like a normal size.
Running super swampers, they are very noisy on the road, and they do wear out faster when driven on pavement a lot. I have learned that lesson.
As far as bead lock rims, you need to check with your local DMV, many states and counties it is illegal to run bead locks on the road.
