I’ve been using the Michelin Pilot Sport AS3+ for a couple years now, and they’ve been great. Very responsive, no tire roll in the corners and great for all season (I live in an area with only light rain and no snow). My WRX is mainly a commuter car, no track or anything like that.

That being said, are the Michelin Pilot Sport 4’s the only tire worth looking at, or are there some others that might fit my needs.
