This review builds on an initial review I did a year ago. When new, dry performance is flawless, high level of grip and very good feedback and handling. In this regard, I would put them over the PS4 and a little bit under the PS2(N3). Surprisingly, the PZ4 is really silent and comfy, which is also a plus for motorway and long trips. On rain they are acceptable. Unfortunately, I think performance decreases significantly as they wear: very slippery on wet (not even rain) and noisy. OK on dry. Lasted about 40 thousand km.
Will not buy again. Moved to Bridgestone Potenza Sport, which, IMO, performs better in any regard.

Good tire, Grips well especially in the dry and dry braking is GOOD. But at 30,000km this set is just about toast - and as they aren't cheap I'll be looking for something to last a bit longer.

Got PZ4 RFT on a new M340i LCI. It's love-hate relationship so far. Above average in the dry, but lacking grip at the limit. Very poor in the wet, car is tail happy even at low speeds. Comfort is fine, not very noisy.
They are ok, but my previous PS4 (not S) were more linear and predictable in all situations, especially in the wet and cold. Could drive them at 2 degrees C with no problem at all.

Good predictability in the dry, I didn't particularly dare in the wet, the front tires wear out quite quickly, especially if you use the car properly.

Even on the track, they were predictable and sticky, not the same as a semi-slick of course but in its class one of if not the best.
Noted I have the Sport with the Tire protection
A great-performance tire and a good allrounder, Perfect for the sporty daily driver

Aquaplaning resistance is the only thing I'm not so fond of.

Good tire, especially in comparison to the standard fit Turanza. No cons so far. Good bang for the buck on this size.

Amazing summer tires, dry grip is incredible, displaces water very well. BAD for snow (lol)

Used them tp replace the all seasons on the front axle, driven fpr around 3.000km, they grip very good on dry tarmac, i did not drive in the wet except when the roads were a bit damp, but they were confident enought, and did not get any surprises.
They do very well on heavy braking, and are comfortable enought. So far no wear on them but not really driven that much. I drive the car on street , in a spirited manner. Sp far very happy with them, once the Pzero allseasons on the other axle will wear, i will also use Pzero pz4 as i am satisfied woth them.

Much better than I thought. Wet excellent dry fine. I would try something else next time as when wear down to 4mm they are noisy. Sidewalls are ok softish load rating. Car is Stelvio QF so powerful heavyish. I don’t do track so want same grip but more refinement.

Good tire in a warm weather (over 15c). It is dangerous when worn down to 3mm and less on a wet in cold weather. It is aquaplaning like crazy.

OEM tire for the Taycan GTS. Quite a ride I had with these tires. The Taycan is nothing to play with. It is a 600hp, 2,3 tone, elecric beast with instant torque. This NF0 version of the PZ4 can really hold its own ground against this car. Dry performance is excellent, you can pretty much do whatever you want to do. Traction is great, balance is great, steering is delightful even when you push really hard. Really love it. My only complaint is that it is a bit clumsy when it begins to slide. You get used to it through, it is not something really scary. Wet perfomance is equally good. A click below dry performance but very good overall. Comfort is kind of average, same goes for noise, it is actually a bit noisy. I really liked this tire, until...I decided to try dry drifting. The tire was literally torn to pieces after 4-5 minutes (not consecutive). Half the tire was gone after this very short session. It really cannot handle it and I am quite surprised that it is approved by Porsche for OEM. Did the same thing with different tire setup and it was just fine (considering the weight of the car). I bought a second pair right after and tried wet drifting this time. Same thing! Much less this time, but a few tire blocks were once again detached. I now have a weird love and hate relatiosnhip with this tire. Will not buy them again, even though I admire what they can do.

These tires are very good when new, providing everything beyond expectations in terms of handling, comfort and feedback. However, they wear down very fast. Drove about 20k kms on these tires and they get chewed up awfully fast, especially in the front given the car I drive is AWD. My feeling is that these tires perform better on RWD vehicles.

As the wear progresses, these tires start to lose the great characteristics that they once had - fast. First thing that is the most noticable is the noise. I believe the thread pattern of these tires influence the noise dampening, as as they wear down, it loses a lot of that ability. Second thing that you will start to feel is the reactiveness. The sidewalls begin to feel rather soft and you do not get the same kind of precision as you would when new to around 5k kms

I have switched to the Michelin PS5's since, and am finding them a lot better in terms of comfort, and similar in terms of performance.
