I just picked up an 11 wrx and the tires need replacing. The front two are at 7 but the rear left is at 4 and the rear right is at 2. I am considering a set of yokohamas, conti dws (have experience with these) or the stock summer tires. I know the debate about using all seasons so please refrain from cluttering up another thread with it. What I am looking for is the tread life on the stock tires and road noise levels with them? I know they will out handle the all seasons but I have another month and a half of winter so I don't think putting summers on right now is the best choice either. What was your experience with the stock dunlops?
