I have a '01 530i with sport package (i.e. 17" wheels). When I purchased the car new the car had michelin primacy's. After 3000 miles the tires feathered so much that it seemed like I was driving a Mack truck. At the time the tires were so new that there was no history on it occuring before. So BMW replaced the tires at 6000 miles after much effort on my part and after an alignment. BMW replaced it with the same Michelin Primacy's. Again the same thing happened 3000 miles later. They blamed it on me as usual, so I went to Michelin. They blamed it on BMW but in good faith replaced the tires but installed michelin pilot sport A/S at 17000 miles. A great tire I must say. Now we are 15K miles later and these tire are doing the same thing. Excessive wear on the outside of the tires (all 4) and feathering. Anyone had this problem????? I have performed about 15 alignments so far with only 35k miles on it. BMW doesn't know what to do, michelin blames it on the car and I am stuck in the middle. Any ideas on what could cause this issue besides alingment. They did find that the camber is out of spec by a hair but BMW and the tire store do not seem to think that it could affect the tires to wear like this. Any ideas.... By the way the car has never been wreaked.... Has anyone experienced the same situation.... I know that others with 530i with sport packages have complained about feathering on the primacy's, that is why we went to michelin pilot sport A/S. However I have seen no complaints about the pilot sport A/S.
