These handle very well. In fact these are the second set of them I have owned (slightly different compound now). That being said, I did enjoy the first set MUCH better. I am not sure what they did to these ones but I will never buy them again. In fact I will not be buying Continental Tires any time soon based on the customer service reply I received about my issue (read on). The issue I have are the flat spots when you park the car. The colder it is outside the worse it is. With the first set of these the flat spots would go away about 1-2km down the road (in any temperature) but with these, they never really 100% do. They are way worse then the first ones when it is REALLY cold out. It does get better the longer you drive but it never really goes away. Continental reply to me was "this is normal with high performance tires."
To be honesty, over the past few years I have taken the tires to FOUR different shops to have them balanced to see if it would help (even doing the full roadforce diagnostic). Every shop says they are good but the faster you go the worse it gets (over 120km/hr) the car has a slight bounce. It will not go away. When I put my winter tires/rims on the bounce/shake is gone. Anyways, now that I have used them for 4 summers they are VERY VERY slippery in the wet so I will be getting rid of them soon. I am nowhere near the 90,000 mile tread life that they claim (def. not the 700 tread wear rating like their website says). If you want a tire for the summer that handles very well (when they are newer) get these. They are not as quiet as my winter tires but the noise isn't bad. I never used them on ice or deep snow.
