By recommendation of the staff here, I tried this tire and I have been most thankful I did. I've got over 3000 miles, they're wearing great-plenty of miles left-and I've only had ONE puncture (that was this crazy, big goat head thorn that would've punctured anything). Thanks, WBW!
I've been on Continentals Grand Prix since 1995. There is no better tire for the combination of performance and puncture resistance. Love them. Racing or training, these get well over a season of miles on them (5000).
I put over 3,000 miles on the last Continental Grand Prix 4000S. It is easy to install and the wear indicators provide an idea of how much tread is left on the tire.
