My view on this. Like he said, the 4S tires are perfect for high performance summer road use. They have a better tread wear than the OEM. The Goodyear's are better for track conditions but not purpose built in my opinion. The tread wear on good track tires should be somewhere between 75-100 if i'm right. The Goodyear's seem to fall right between summer road tires and track tires.
The Goodyears are the best option if you wanted one set of tires to do it all. But they aren't great for the track or great for the road. When these are toast, i plan on running the 4S for the road (or a different tire with a better tread wear), and getting a dedicated track tire/wheel. That's how it should be done
