But these tires diminished the road noise by at least 50%---maybe a lot more. Z became a totally different, comfortable car and the ride even felt less harsh and stiff. I don't track my car and handling/performance are not my priorities. Talk to Tire Rack or your local guy. It was the best $850 or so I ever spent (and these tires may also last longer than the stock performance tires).
