I don't want to deal with separate snow tire hassle, storage and cost, so I try compromising with high-performance A/S tires. While I will give Michelin high marks for it's Pilot A/S+ all-around strong performance, good dry and wet performance, good enough snow performance to get me home in 3 inches of snow (in a 360hp rwd 550i); I frankly expect this for $200/tire. What I don't expect is 3/32 of tread left after only 14,000 miles, consisting mainly of my boring 6 mile commute to work. This is pathetic. The 500AA treadwear rating is a joke. I rotated every 6,000 miles to keep up with warranty requirements. Oh, there is another joke, the 45,000 mile warranty. Since the middle of the tire is worn down to the wear bars, but both outside treads have plenty of tread left, this is considered 'uneven wear' and will void the warranty. This is borderline fraud. Maybe if you drive a Prius, these tires will wear evenly, but they are marketed as the ultimate in A/S high performance, and I dare Michelin to show me a real performance car where these things will wear evenly for 45,000 miles. Stay away unless you don't mind shelling out $800 every 14-16k miles for new tires. I'm certainly not going to buy another pair.
