I leased this vehicle end of September 2016 but have replaced tires 6 times within last two years due to bubble in side of the tires. I don't think it is issue with tires since I have 2016 BMW with same tires without any issues. It could the rim size or the suspension on this vehicle cause tires to bubble up. I have been leasing cars for 30 years and never had issues like this. Numerous time I have asked the dealer to find out the root cause for it but no luck so far. The issue here is it putting myself and my family danger of our life because it is happening without even going thru a pot hole.each time when it happened, it is causing me to spend 350 to replace each tire. The transmission also failed last week while I was driving on a highway but lucky I was able to pull to a side without getting hit by another car.the transmission should not fail when the car only have $37,000 miles. I am not sure if any other complains was files regarding the same issues. I want Benz to replace these tires at free of cost till they find out the issue and fix it.

The tires blew out on the NJ turnpike while driving approximately 67 miles per hour. They are pirelli cinturato P7 run flat 225 40R18. One of the other tires has a bubble in it. The vehicles lost control and was swerving severely right and left almost doing a full 180 degree turn in the middle of the highway which nearly hit other vehicles driving over 65 miles per hour. Vehicle is 2 years old and had tire issues at least 4 times prior to this incident. Tire had pressure issue and was taken for service to Mercedes of cherry hill NJ approximately a month before this blow out.

We purchased a brand new Mercedes Benz 2016 5 months ago. I am driving about 28 miles from my starting point and come to find two of my front tires with air bubbles. Come to find out 1 of my tires eventually popped and the other still had an air bubble. Took it to Benz dealership and was told nothing can be replaced under warranty. Pretty much they are selling defective tires and not offering any sort of replacement or prorated coverage. I drove from queens, NY to New Jersey. Parked the car for 4 hours and saw one of the tires go flat after it had a bubble. What was worse is that I could have been involved in a crash/accident with these defective tires.
