I bought these because I drive about 50k miles a year for work. They had a great warranty and I didn't feel like going with a lesser tire and replacing them every 6 months. What a pleasure they are. I replaced the factory run flats, and the ride felt much better. NC downpours are no problem, just now at 51k miles did I first feel the slightest bit of hydroplaning, and I am pretty much at the wear bars. They have been very quiet until the last 2k miles, now they are noisy, but again, I can't complain. I'm 6k miles past the warranty (28k past the warranty for the rears since they are larger than the front). I'm buying another set right now, that's why I'm on the website now writing the review.
