These tires were an upgrade to PS2's and although similar in nature, the Super Sports are a huge upgrade. I can't comment on the tread life but the tire is very soft and sticky to the touch - more than any other street tire I've owned. They immediately feel like there is 25% more tire gripping the road but the turn in is much quicker and requires less effort. Ride feels more controlled - no squishy feeling when cornering on throttle, but is also softer when going over uneven, broken road surfaces - car doesn't shake up and down or side to side as much as the PS2s - very compliant. Probably a 50% improvement in ride quality and quieter than the PS2s. Wet grip is awesome - no sense of hydroplaning up to 130km/h in misty conditions and I couldn't even get the tires to start to break away at 80km/h on damp backroad highways. Overall a very worthwhile upgrade on the PS2s.
