When I first got these tires, I was a little disappointed. They felt a little greasy or nervous on the highway. Well, that impression is gone. They've aged remarkably well and show signs of going many more miles. I have to say they are probably one of the best tires I've ever owned, and I've had a lot of cars from Mercedes E class down to my lowly Saturn commuter beater. Outstanding combination of elements...efficiency, ride, noise, traction. I think you'd be hard pressed to find a better overall compromise for this price. I just bought another set of them for one of my other cars today.
