I have close to 40K on these tires. My WRX was stage 1 w about 240 whp and then moved to stage 2 with about 270-280whp. I have pushed these tires, they perform pretty well. Tread design is a tad boring but they do well in the wet and dry. Not as good as a true summer tires but better than past all seasons I have had. I have a set of Conti DW06 on 18" wheels as well, they are a tad quieter but cost more as well, They are not as stiff as the Pirellis. Next will be BF Goodrich Comp 2 A/S. The Pirellis are not bad in the snow, you just have to remind yourself that any all season under 7 degrees wil not perform as well as a true snow tire but for this odd winter in Vancouver they have done pretty well. I am expecting I will get about 50KM out of them so am looking for my next tire now
Be ready for the shakes. I purchased a set of these tires for my summer wheels from Discount Tire and literally HATE these tires. On a dry 75 degree day or warmer they are "ok" but anything else these tires are awful. They shake in cold weather until the tires warm up. My stock wheel and tire doesn't do that at all under the same weather condition. When hanging lanes, you can feel the sidewalk sagging. In rain, these tires are like driving on ice. They go everywhere. I would NEVER recommend these tires to anyone. Even if it was for a winter beater. Worst tire I have ever had. Will be purchasing Yokohama like I should have done before this mistake.
I bought these tires today and within 20 mins I feel all the bumps just like dunlop sport maxx rt (summer tires). Good grip on the road but very noisy. I thought my Subaru rumble would overpower the road noise but it's louder than my engine and exhaust. Don't know about the snow weather but it's required to give a rating.
