This is my first experience with Conti's that I can say was outstanding! I am a very spirited driver in Michigan, in the worst winter we have had in 50 years and these tires performed wonderfully! 20K and these tires are still going strong and still handle competently. The only negatives (but very nominal negative) is they do generate just a bit of road noise, the sacrifice was comfort for handling (they don't take bumps great)but they are absolutely outstanding in the turns, on wet pavement and in the snow. For you high end tech. guys......These tires road-force wonderfully! I have installed 2 sets and every tire road forced to less than 10 lbs and balanced with minimal weights. The last set I installed (205 50 16's) only required a total of 3 ounces of wheel weights for all 4 tires and the tire with the worst road force numbers had 9 lbs of road force. These are GREAT tires! Forget about the Continentals of yester-year!
