I replaced Michelin A/S3 (ultra high performance all season)with the so4 (max performance summer) about 2000 miles ago and had nothing but disappointments.
1. The tire contact patch is 1 inch smaller compared to the michelins and the overall circumference is shorter, thus making my tire/wheel look "mismatch and small" to the car
2. The tires will not warm up to performance standards unless it's in 90 degree Florida heat. Today after driving 40 miles on I95, the tires still broke loose for a good 3 seconds at WOT from a stop light on a clean unsandy street. Indicated temp on dash was 75 degrees
3. But the tire is so soft that even with mild acceleration to 3k rpm from a stop will leave a trail of tire marks on the pavement. I can see it from my rear view mirror. Doubt they will last over 8k miles
4. The SO4 also tend to hydroplane much easier going through a puddle.

With the A/S3 those issues weren't existent and the rears lasted over 12k with over 50 drag race runs with burnouts. Best time 12.91 1/4 mile.
Reason I bought the so4 was based on the cheaper price and PSS is on a long wait list since every high performance car is using it from the factory.

I also had the Hankook v12 evo before the michelins. I would give them a higher initial rating than the so4
