    H = 130 mph
    Z = 149+mph

    For old retired couples that use their 2002 WS6 to cruise to Bob Evans on Sunday afternoons and never hit 75+mph, H would be alright. Otherwise, a performance car needs performance tires.

    don't get hung up on the speed ratings. with higher speed ratings, it means the tire is capable of better handling as well. independant tests have show when going from a S (112 mph) to a H (130) rated tire, the vehicle can stop about 11 feet quicker. due to tire component construction, the tire doesn't distort near as much. this leaves a wider tread footprint which means better grip.
