The tires I purchased came after a short running time (estimated to about 10% attrition) over average road noise, which became unbearable over time. Unfortunately, it turned out only when my 2nd visit Werkt Instead, the tires have a pronounced heel and toe. On the recommendation of my workshop, the tires were objected to by me at Michelin. Their "technical department" came to the conclusion that the offending tire an advanced wear (abrasion 25%) would have. A measurement of the concentricity was stated to be therefore no longer performed as a statement about the condition of the tires when new at this Grand wear is no longer possible. (??) Finally saw Mr FB of the company. Michelin allegedly "not got a chance to make under warranty replacement". In an extensive 2-page letter I described the company. Michelin then again the exact loss experience, presented a letter from my dealership at where this was also confirmed and asked to submit a goodwill offering. (!) Already three weeks later, I received from the company Michelin an ME from standard text blocks composite short letter in which you me -. Without going into a sentence to my letter - announced that they "no way see to refund" and you would appreciate it if I could examine the tires of another appropriate institution. As already mentioned above, I had (!) Let the tires already from my dealership 2 x inspect and this came to the conclusion that the tires would have a "clear heel and toe". For me as a consumer to OA represents operation so that with my tire failure leaves out in the cold alone the company. Michelin. Come to think of litigation in relation appears too costly for the small claims, I'll accept that my supposedly highly durable tires are ripe for the special after a total mileage of only 15,000 km, where I'll bring it today towards. Since the tires were evaluated in principle well in various test reports, I basically the development of fuel-saving tires find very good and also'm not a tire specialist, I would like to conclude not judge about the "Energy Saver", since it may well be that I " Monday tires "have caught. However, before the above background, I feel the customer service of the company. Michelin very unkulant and unprofessional and will therefore in future certainly acquire any tire of this company more.
