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.

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 tire but not very enduring. extraordinary dry/wet handling. no hydroplaning. grips curves well beyond the limits. except that after 12,000 km, only 5/32 remains. not very durable and very expensive

Switched from Michelin Primacy to the 4s and the ride quality and handling improvement was a nice upgrade. I live in a fairly warm climate with good road surfaces.

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..!!!

Great tires that are able to transfer >650hp to the pavement well, are very responsive in corners, quiet, and they have an outstanding mileage warranty! I highly recommend these summer tires!!

These were the original tires that came with my Mercedes GLE53 AMG Coupe. I have about 15000 miles on them but I'm see the following issues in the sidewall of the front tires. Not sure if it's wear issue or something else...

I bought these for track days and they work great on track ,only thing my car weights a little more than the sidewalls can handle, the grip wet and dry is awesome ,I graduated them to street duty and the comfort is extrodenary

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.

I have about 1,500 miles on these tires that I bought new. However, on one of the tires are two, approximate 1” vertical bulges protruding outward. Is this normal? Great looking/handling tires, other than the defects.
