It's been awhile since I posted but i am having an annoying problem. On my 1984 733i, m-suspension, the right rear tire develops a worn ring around the inside of the tire. This has happened on two tires now. No, it is not the allignment, which is what the garage keeps telling me, but on this last set I have had it alligned three times in six months. (you bump up the curbs here alot)(to park or let other cars by)(Germany) The other three tires still look like new but this one is almost to the cords on about 2 inches of the inside. Yes, it has been a four wheel alignment. The springs are a bit weak but on both sides.

Any ideas?
