My tire is Michelin Pilot HX-MXM4, 245/40R18 93V M+S. The tire is on My 2009 MB300E4matic. The front driver side tire had a big tear about half of the outer circle in the inner sidewall. The car itself has 62000 kms, since I use winter tires that means this tire is under 50000 kms for sure. I know the warranty will be expired after 6 years but it is ridiculous that the tire won’t last over 50000 Km and put my life in risk. I contact the customer service, they tell me the tire is over 6 years old and there is nothing they can do. So, why you advertise something like 70000, 80000 and 100000 Km warranties? These are not cheap tires. I rotate and balance them once a year. The tires have never been driven in winter and it fell apart just under 50K! Shame on you! Will never buy again! I was lucky because the car detected something wrong with the tire pressure so I stopped before I got killed. I was so shocked when I saw the big tear! If you want a tire that will stop you in the middle of nowhere and risk your life then go ahead buy it. Anyone interested to see the photo just ask me, I like to share with you to see how bad the tire is!
