OK Guys thanks for the effort, However, there are too many irrelevant guessing and assumptions. Are you ready to be educated?
Here we go: 1. I drive conservativly and very skimpy on my brakes. 2) You can even say that I baby my car. 3). I do not make jack rabbit starts, rip around corners and I get 27.6 MPG combined city/highway. 3). I usually get 70,000 miles on a set of michilin with lots of ride to go. 4). My car is always in tip top shape in every respect. My tires are Bridgestone Potenza installed at approx $500 .00
No front end, tie rod or ball joint issues. The BMW dealer basically told me to enjoy the ride from my $5,000.00 worth of sports suspension options. Thats when he lost me!
My Research led me to a mechanic who knows suspensions and particularly BMW and Mercedes Benz. The problem was the BMW Dealer-- Not the Car. They make a lot of money selling tires and deliberately set up the car with Excessive Negative camber. They told me that it is within specs. They wont change it, citing that it will lead to suspension and front end problems. WRONG, WRONG, WRONG.
I trusted this mechani over at Tire Plus he adjusted the Camber to something slightly negative. About 10 percent of what BMW told me and replaced the tires at 64,000 miles. My tires are now about 50% worn with 103,000 total miles. They wear evenly and the ride is still great.
I Love this Car!!! BMW has zero credibility with this BMW owner.
