Tires performance as described. A little on the expensive side.

Both my car and I love these tires!

Great tires ! Now my Porsche feel much better. Tire Rack best place to buy and have your new tires installed.

Have driven for one season on these tires. Love the way they roll and track true so you aren’t correcting the steering like so many other brands. A little more tire noise than the x-ice tires but excellent handelling.

After exchanging the all season tires to the summer tires, the grip and performance on summer version tires is a big difference. Soo much better. Bravo

Had new PZero on the C4 GTS I bought and almost immediately, LOUD AS HELL…. Even though I’ve only driven about 150 miles, feel so much better and… QUIETER..!!!

Good for summer/wet weather, but you should NOT use these in the extreme cold winter months we see in the Midwest. The rubber compound in these tires will harden and, potentially, crack.

Great tires, however contact patch seems to be narrower than previous generations and doesn’t look as wide and aggressive as previous. But performance/comfort/noise wise, best tires out there

While these tires had excellent performance in dry and wet, they were too fragile, i had one go out due manufactuer defect. Then another another one go out from hitting pot hole.

Absolutely the best tires I've ever had. I have pushed them to the limit and can not believe they hold the road like they do. A great road tire as the ride quality is amazing also. You feel the road but no discomfort.
