I got these tires to replace my stock tires. I put about 75k miles on them and I never had issues with them. The grip on the road is amazing, I always drove my Forester with confidence that the tires would grip the road. On dry pavement I always felt like the car would tip over before the tire would loose grip in a sharp turn.
The bad side is that they are loud. I mean if you drive over 50mph you will hear the tires roll down the road. I basically gave up having long phone conversation while on the interstate at speeds above 70mph.
I'm looking now to get new tires and I'm torn. I love the performance aspect of these tires but I'm not sure I want to put up with the noise level.
