The local Discount Tire does not carry Kumho and Avid Touring had 'S' only rating. That force me to consider Falken 512 - Consumer Report #1 recommended tire. After reading many reviews (mostly good), I decided to go ahead and put them on.
The Falken is significantly quieter and ride is better. Every area seems better than my old Symmetry where I paid $100 each. Falken is only $260 on all 4, out the door! I'm not likely to go back to Michelin.
