These were fitted after the OEM tire, a Michelin Primacy, and were wholly transformative for the communication, handling and limit behaviour of the FR-S (also Toyota 86, Suabru BRZ) chassis. The limit was higher, and the breakaway was transparent, smooth and controllable. In the dry, they were a massive improvement, but in the wet, even more so over OEM. The wet grip felt like 80% of the dry grip, meaning I had total confidence in anything but a giant, hydroplane-inducing puddle. Even if there was one side of the car in an unavoidable puddle at speed, I wasn't worried because the other side of the car had sufficient grip.
I did not use them in the snow or ice.
I am not a driver concerned about wear or tire life - I value handling feel and grip over comfort and life. I had no issues with either the comfort of the wear rate of the tires. After a particularly spirited drive, the shoulders would show signs of wear, but that would clean up after a week or so of sedate commuting.
The only complaint was that there was a minor delay (or lack of instant response) around center at highway speeds. But these are All Seasons, and the wet weather performance more than made up for that minor gripe. I recommend these to anyone who drives spiritedly, especially in locations that get lots of rain - like the Pacific Northwest and similar areas.
