First, I put these tires on my wife's 2004 Lexus RX330 and my daughter's 2008 Honda Civic. I tested these tires on both cars for months. My ProContacts were at 2/32 after 30,000 miles and Continental gave me some money back on those. These tires perform better or equal to the ProContacts at a lower cost. Yesterday we had a snow storm, the tires never broke or threw me to the side in slush. The can be mushy during high speed cornering, but I run my pressure at 39 front and 37 rear so this helps. They are a little noisy but not anything that should stop you from purchasing. I think it might be the large outer blocks that create some noise. In the rain, they don't hydroplane, and it gives you a good confidence feel at high speed. The tread wear seems acceptable so far, on the Audi, Lexus and Honda. The DWS all still showing even after 12,000 miles on the Lexus. I have not noticed any balancing or vibration issues on all 3 vehicles. My tire shop has a very good balance machine, so this might help. This is my 3rd set purchased of Continental PureContact's so if that tells you anything. One more point, I have not noticed any mileage increases on all 3 vehicles. I think it saves fuel over time, so nothing to note on fill ups.
