These tires are absolute garbage! I bought them in May /15 and within a week noticed that the tires on the passenger side looked really low. I went into the auto centre where I purchased them and was told that 1/2 the air had leaked out of the passenger side tires, they replaced the valve stems. 3 months later I was about to go out of town to visit a friend and noticed the back tire on the driver side was low. I took it in to another tire place and they replaced the valve stem. Last summer I lost 1/2 the air out of all tires and all valve stems were replaced again. 2 weeks ago the front passenger side tire deflated and I had to get a new tire. The other front tire has enough air in it but it's soft and looks smooshed. I do not do a lot of driving. I live 5 min. away from work and am close to all amenities. I've had so many problems with these tires that I have started to avoid busier expressways, etc. I know that I'm going to replace the remaining 3 tires soon and I've only had them for a little over 2 years. I am so disappointed with my tires and will never buy Michelin again.
