These Conti's are the OE tires on my Audi A6 3.0T. I am fanatical about keeping the tire pressures correct and rotating tires around every 6K miles. I am at just over 30K miles on them and probably have about 5K left of treadwear. I was surprised to see that they had a 60K warranty on treadwear. I do have to say in the tire's defense that I drive hard on tires and have a supercharged AWD car, so I don't think the treadwear on mine is bad compared with other tires on other vehicles. I gave a 7 on treadwear only because of the stated warranty claim versus my actual mileage on them. I have driven in rain and light snow and these tires gave me confidence to drive faster than I probably should. At times, I have tried to achieve tire slip in straight exceleration and turning while excelerating. These tires hold the pavement surprisingly well for an all-season touring tire. I would almost lump this tire in the performance tire category for how it performs under hard driving. My last not is that it is relatively quite while driving on the interstate. Other similar tires I owned had a high-pitched tire whine at speed. It's time for me to replace these OEs and I will strongly consider another set of 5 (full size spare too).
