One problem related to tire bubble has been reported for the 2006 Mercedes Benz E550. The most recently reported issues are listed below.
Dear sir/madam, I have a serious complaint against the continental contiprocontact tires that came with my Mercedes Benz E550 and also the new ones I recently purchased. The car has only 20k miles on it and the side walls on the tires are very weak. I had 1 bubble each develop on 2 of the tires that came with the car after driving over 2 small potholes recently. I also had a sidewall issue on the third tire that came with the car and the new one I just purchased. The recent incident was the worst where both sidewalls burst open when I hit a pot hole. I really think that the quality of the tires is very poor because it seems to be impacting the sidewalls. I would like to discuss this with someone at the supervisor and director level because this is a very serious complaint. I am also going to place a complaint with the indiana department of transport for their lack of fixing these pot holes on-time. I am thoroughly disappointed with the road conditions.
