15K, but I don't think they only last 12-15, according to tirerack if they were under a year and under 20k were covered under the warranty, but the tires have to wear even, which wasn;t my case.. So I'm assuming at least 20k. Michelins PS2 Sport aren't cheap and 12-15k would be a little too low for the price paid..

 

If you're shocks are weak (increased load = increased negative camber) and running something >= -2.0 degrees of camber I could see that happening in 15k especially if you do a lot of straight line driving.
Not to thread drop but I'm selling a rear camber kit from Bav Auto. Let me know if you're interested.

I don't want to argue, but the premium price for PS2's is for performance, not durability. Period. The compounds used on these tires prioritize grip. I've been driving on high-end sport tires for years and, in my experience, 15K is about all you can expect, unless you don't mind driving on worn (borderline dangerous) tires.

If you can get warranty satisfaction from Tire Rack, go for it. But Tire Rack's policy doesn't change the fact that performance tires wear quickly. If you want durability, I'm afraid you'll need to sacrifice performance and get some "touring" tires. Facts of life.

 

All i was saying what tirerack rep. told me that the Michelin PS2 sport tires come with warranty, I believe it was the factory one. Like i said b4 they offered me credit if the tires we worn evenly.. Which was not my case . I thru the tires out.
i'm sorry if i gave you the impression that I was truing to argue just my 2c..

 

Also keep in mind there are very clear specs on the alignments process with weights and certain a fuel load. If you are going to Tire Kingdom, these Prince's ignore this. Best shot is an idny shop that is familiar or back to the dealer. I've actually had the best luck with alignments from my dealer...

 

+1 My dealer runs service "specials" regularly -- your local BMW shops may too if you're trying to save a few $'s. Otherwise, look for an indy with BMW experience and strong positive references. In my opinion just because a shop "specializes" in alignments, it doesn't automatically make them "expert" [e.g. a hooker may not make a great wife]

 

Between a dealer and indy shop isn't much of the $$ saving, not sure how well dealer will do it, certainly will give'em a shot..

 

15k miles sounds above average for a sport tire, on sport suspension.

 

Wtf, you let them get that bad...wow! Why?

 

so be honest .. your doing burn out's or something.


if your car is having suspension issues , have a friend follow you while you drive. Have them look at all of your wheels as you drive on the street or freeway. If your wheel hops, wobbles , or has any type of movement then you know for sure it's a suspension problem.

Your rear wheel bearings might be bad .. do you hear any howling sounds as you drive ?
