Ok. I live in Michigan and I have bought these tires on April 2012. Starting from April to winter tires got mileage around 15k miles and tread came from 9 to less then 4mm. Totally crap. That's not all.
Already in September I heard noise from rear. I thought is't right bearing wheel, but when switched on Nov to winter tires nose is gone! Whole winter I didn't hear it (thanks to Dunlop - Graspic DS-3 - good tires for winter, and already on my 2nd car). How I hear vibration noise again. And most bad thing that tire service said that "to hard to balance this tires". They even gave discount for next time because this tires will not live than 2 month with my annual mileage.
Definitively will buy again Michelin. Expansive but really good tires.
bought these tires from costco kept on bringing them back to be rotated tires are very very loud! I am very dissatisfied wish i never bought them. costco has every excuse in the book to not take them back or exchange them for another set of tires and I told them I am willing to pay the wear charges just give me quiet tires! Im sure they know about the noise and had more complaints. sad that a store that huge cant satisfy their loyal customers! they ar also very hard on bumps.
