New tires installed: BF Goodrich G-Force Comp-2 A/S. Overall grip and cornering is better than the Firestone FR740s (i.e. Corolla S tires) that the car came with (although not as good as a dedicated summer tire), and the car feels less floaty. Braking should be better for emergency stops. Rain performance is good; the tires do a nice job of cutting through the water. Also, the tires don't look as skinny/narrow as the Firestones, even though they're the same width. I guess the aggressive tread pattern provides the illusion of a wider tire.
