Coming from Continental tires on the rear and Khumo's on the front, I feel like I just bought a brand new car. The Tirerack reviews were very helpful. I chose the tires with the highest review ratings for my driving habits and am exceptionally pleased with the results. Most impressive is the overall quietness of them; something important to me as a daily highway driver. I had previously scheduled an appointment for dynamating the rear but now I won't need to. The ride seems smoother as well.
