You know, nobody ever mentions the fact that you can get rims repaired, you don't really need to buy new ones.
Look in the phone book under auto repair, or in the back of tuner magazines. also, many body shops can repair rims too (I've had it done that way before). it's much cheaper than buying replacement rims, and they will be nice & round, perfectly balanced and stronger than ever when they're done.
Until you get to know the roads in the city, keep an eye out for those potholes. after a while, you get to know where all the potholes are at. they will only kill the rims if you are going fast when you hit them, if you take them slow, they won't mess your rims up (BTW, 35 MPH over a deep pothole is too fast; it's better to just avoid them if you can't slow down.
either that, or buy a set of steelies for daily driving, and save your nice ones for racing or shows.
