These tires were bought to replace a full set on my STS-V. First of all the tires on the car were runflats, hard noisy tires as this car does not have a spare. The car also comes staggered 18 wheel up front 19 out back so that in its own creates a lot of fun tire shopping. I went back and forth for a full month these, pirelli, BFG's and so on. Im so glad I got these. So far 15000 miles on them this is 1 year of driving they have minimal wear. They come with D W S stamped in them Dry Wet Snow. These tires all 4 and mind you I can not rotate them still have the Snow indication of the depth of tread left. On the highway they are very quiet and smooth, no road noise all the way up to and beyond legal speeds. In the rain even at ludcris speeds very very stable and in Florida the rain comes hard and puddles are deep in a matter of minutes no hydroplaning issues to speak of. Cornering does give up a few points as they are a softer tire so if your looking for a hardcore autocross tire move on to your noisy tires this one is not for you. Straight line dry these tires let all 469 horsepower get down with very minimal spin. In wet there is one odd thing to them is just a tad to much power from a stop they will allow spin, but once your moving I can once again full power without issue. These tires have by far exceded my expectations for this car, and when that 55k miles comes up for replacement I have no doubt in my mind it will be these again.
