I have a 2004 with about 30000 miles on her. When I bought it a year ago it had a slight vibration in the rear at 65-70 mph, Took it to have tires bal.They said it had a slight bent rim. Well after buying it I didn't have the money to buy a new rim and I don't drive that fast very often. Now I can afford to get a rim. So I thought I would jack it up to check it out. The one they said was bent has what I would call a slight flat spot in the rim. So while I had it up I looked at the other rim and it has a slight wiggle in the rim in one spot Both tires run true though. Is it normal for rims to not be perfect?
