Purchased in 2009 to replace factory tires on my car. After not being able to drive through lightly packed snow on mountain pass roads and getting stuck overnight waiting on the nearest (and only) gas station in the area to open up to buy snow chains, I decided a highly-rated performance all-season tire purchase was in order, even though the original tires had many miles of tread life left on them. After sifting through countless review websites, I settled on the consistently highest-rated high-performance all-season tires. Although not as inexpensive as other offerings, I can truly say you get what you pay for! with tires. Western Washington roads are some of the worst in the country in regards to tread life, but after more than 3 1/2 years of driving in all weather conditions (mostly wet, with some snow/ice and a fair amount of dry weather) the tires perform as well as on day one. Tread depth is down to 7/32 from the original 10.5/32, which is a very nice surprise after the amount of time and miles driven. Sidewalls stay nice and firm for optimum handling in higher-speed cornering and loss of traction is never an issue during spirited driving with fast starts and hard stops. I will most definitely look to purchase these tires (or their upgrade, if Michelin upgrades them) again when the time comes. You will not be disappointed with this purchase!
