Well, when I bought the car, one of the wheels didn't match... The matching rim was in the trunk, the guy I bought it from explained that the tire was getting worn, so he switched it off... Seemed reasonable... Now I went to get a tire mounted on the matching rim, and they tell me that when they put it on a machine to test the balance on it it's wiggling all over the place...

Where can I go to get the rim fixed, or am I pretty much screwed and gonna hafta buy a new one?
