I'm a 15 year GM world class trained tech and recreational drag/autox gear head. This is my everyday (when it's not snowing) cruiser. It's the factory tire for the car, and I can see why, 255/40ZR19-285/35ZR19. The last performance tire I used on the previous car to this one was was the Nitto INVO and I have zero complaints about it, it was/is an amazing tire but these are nicer. The car is an 09 CTS-V with the Hennessy V650 kit and 1 inch D3 drop and sway bars on it. Even before I did the kit and suspension upgrades the car handled like a dream with the PS2's. The dry traction is second only to drag radials. The cornering grip is nuts, I can push this thing hard into the corners with confidence. Comfortwise they are smooth and don't jar your fillings (have had them up to 165mph and silky smooth). They wear in even and in cars like mine with non-rotatable staggered fitment I still see no bad edge wear. Road noise is next to ZERO. I drive the car hard and they hold up just fine. 20k on them now and I'll probably get another 6-7k out of them. If you expect to get 40k out of a summer performance tire your nuts, especially on cars with staggered fitments like 90% of the cars these tires are going on. I will be replacing these with another set of PS2's. As far as people complaining about wear issues, look at the cars they are driving: 1-staggered fitment will wear more even with a perfect alignment, 2-sport models with more aggressive alignment specs and usually more aggressive driving habbits will wear more even if they aren't aggressive drivers. I saw one complaining about bubbles in the sidewall, stop hitting potholes..... They ---- in the snow but neither the tire nor the car was designed for it. Cold traction is lower to but again, it's a summer compound tire (cold as in 50 degress and less out). I'm extremely happy with the tire, have tried most the competitors on my other cars and can say this one wins.
