Bought a cpo car from mb West chester, pa and immediately noticed front tire(s) making thud sound that is more noticeable at 25-30 mps; although at higher speeds the thud sound continues. Dealer says tire treads are only worn 30%, but recommended new tires (which were supposed to be on the car!!). manufacturer says it sounds like a flat spot on the tire. I even paid for extra warranty and still dealer will not replace tire. Very concerned for safety based on posts of blow-outs, etc. It's amazing that truck tires have been replaced for the same reasons, but not car tires.

We bought 2009 mb E-350 w/sport package which has amg wheels on it. Car has currently 3K miles on it. When my wife was driving, suddenly wheel material pop-out from the middle of the base (18" width) and cause sudden loss of air. Please note that there is no damage to tire (like hole, impact on the area where wheel damaged). We believe that wheel has material/design defect because wheel normally very solid hard to pop-out like this. Even dealer or no-one has seen this kind of incident. My wife is pregnant and she was driving this vehicle and now she is scared to drive this vehicle due to incident. We believe that due to safety of us and for others who are using mb w/amg wheels needs to be examine. If require, I can provide pictures of the wheel and tire.
