These replaced Michelin Pilot A/S tires. Driving away from the shop that mounted them it was apparent immediately that these are much smoother and much quieter than the Michelins. Ride comfort is just much, much better. The next day I checked the tire pressure, the shop had inflated them to 38psi, the recommended psi is 30, which is what I ran the Michelins at. So, over-inflated by almost 30%, and not broken in, they were a much more comfortable tire. Now, after 2000 miles, they're getting even better as they break-in. I'm getting 32 to 33.5 mpg. The Michelins, from their first day to their last, got me 30 to 31.5. Haven't been through a winter yet so can't comment there, and of course it's too early to judge tire wear. But from the first couple months experience I'd say they're terrific. The only slightly odd thing about them is that they get better mileage around town than on the highway. Maybe that will change after full breakin, but I can't complain since 80% of my driving is non-highway.
