After two years, these are coming to the end of their life.
Installed on 6/9 at 114,700 miles and today with 156,300 miles on the odometer, I ordered some Pirelli P7's to replace them.
The W is finally wearing off. I would have pushed them a bit longer, but two of them have nails in them, one has a bulge in the sidewall from a pothole and is now sitting in the garage with another full sized spare installed until the P7's come in. By the time I spend money to have one nail repaired, the other two are not repairable, I could pay for much of the mounting and balancing. Besides, right now there is $70 off the purchase of 4 Pirelli tires at Sam's Club, so it's a no-brainer.
So about 42K miles on tires warrantied for 50K. Not worth spending the extra cash trying to get another 10-12K miles out of the tires.
My only complaint, and not really a valid one, is that these only last about 50K miles. I'm hoping for at least one more year out of the P7's
