I'm driving those tires in Fort Lauderdale, Florida, 75% Highway-25%City. Installed at 40k miles (11/2010), have 80k miles and still 50% of thread left (hopefully to get at least 20-25k more miles). Overall a good tire for commuting and some sporty driving from time to time. At the beginning I was impressed with the noise level (was far better than the Continental stock tire which was $60/tire more expensive than this one), but now the noise level went up. Not sure if it's the tire or something else. Have to mention I didn't do any tire rotation and they are evenly worn. Even on heavy rain I drive 75mph on the highway and they feel good. I didn't have to do any emergency breaks dry/wet. Had several hard breaks and it was OK.
