Why are these rated so highly and why does mercedes insist on putting them on?

Had on a mercedes SLK55. The back end had zero grip in the damp - wear was horrendous.

I don't get why these tires are rated so highly

I really like Pzeros. They are very good tires both on wet and dry. After 19.000 km they have 4.5mm thread left. I would definetely buy them again if I could find them V rated 205/50/17 because I am thinking of going oem size,now upgrated to 225/45/17. They need so mssometime in

Granted, a lot of the grip of this car comes from the excellent chassis and suspension but these tires are a perfect pairing for the car. The only minor point is that they seemed to wear a little quickly but that could be down to the driving style as much as the tire itself.
In the wet and dry they are a grippy, safe and fun tire that I'd imagine would be a great choice on any sports car.

Had these tires for 19,500miles, with 3-4mm left on all four. So as far as wear goes - well impressed.
Had cupra from new n driven damn hard. wet grip lets the pirelli's down for me

I've a jag xf 275cv. This tires has and excellent grip in dry, also last millage. You can go on a cornering roads extremly fast and tires answer is impresive. On wet condicions results are really good but not impresive only in last millage grip starts to be only aceptable, specially on raining conditions when aquaplaning apears.
On motorway has also an excellent grip but noise isn't the best. Fuel consumtion is good for this kind of tires.. however I've changed with 16700 miles because was finished, from my point a short millage.
50% motorway 20% city drive 30% country roads.

Just plain rubbish

Had on a merc SL - The back end was dreadful - wear was horrendous. fronts randomly wore to steel ribbing which I have never had on any tires before and none since.

I don't get why these tires are rated so highly

Very noisy, don't know if it was a bad pick for my car or if these tires are just a bad mix of rubber and etc. Seemed very good for the first 1000km, then they got very noisy and ruff. Stopping is like the car is rolling on chains. Changing lanes is like going over railway tracks.

The P-zero does not get a lot of rave reviews, and many enthusiast drivers bang on about other brands from the "Premium" suppliers.

However I really like Pirelli P-Zero. They are superbly made, of the nicest construction quality, and really good all round.

They look very nice, with an attractive modern asymmetric pattern. Their roadholding is very good, and the comfort levels in terms of noise and harshness are also great. I've not had them long enough to establish longevity and wear rates however. They do have a nice sidewall design with an integral yet unobtrusive kerb-protector. Not all high-performance tires even have this, and it's a very useful feature for any road car.

All in all, in the "ultra-high performance" segment the P-zero is kind of ignored against the Michelin and Goodyear brands, who all have a very vocal fan-base.

But it's worth remembering that the P-Zero is OEM fitment on Porsche, Ferrari, Jaguuar, McLaren, Audi to name but a few.

The only problem with P-Zeros is the confusing nature of the range. Each OEM fitment mentioned above has a specific tire in each size, so you need a tire marked N0 for Porsche, MC1 for McLaren etc. This can get confusing when changing them, and often great cost differences exist even with the same tire sizes.

Another thing is the P-Zero is a particular tire in the P-zero range. There are also P-zero Rosso (comfortable and quiet with soft tread), Nero (ultra-low profile for aftermarket fitments), Silver (hard tread for high mileage users), and System (different tread types front and rear), and corsa (road/race fitment)

This review is for the basic P-Zero, which as mentioned is an all rounder for any high-performance car that comes in a large variety of sizes.

It's a great all round tire that should please everybody. I have them on the back of my Porsche Boxster now, and have just bought two more for the front.

I've tried out lot's of tires the last years and found what others seem to know from the beginning; quality comes from the same brand over again. The last years I've gone from Hankook, Barum, Good Year, Sunny, Nokian, Michelin to Continental, Bridestone and now last season to Pirelli Zero.

What a fantastic tire, grips, holds, responses and performs. Bare in mind I drive a Volvo which is among the worst cars made. I've also been very happy with Bridgestone 050's, but they weigh 1 kg more at the same size, so my choice goes to Continental Sport-series or as now, Pirelli Zero. After 10 km of efficient driving, the surface is already warmed up and grips.

The only downside is the wear. Mine lasted for 12000 km on front axle untile they were below 0,5 mm and I had to change for a set of new ones, the same brand of course.

Very happy with these, but next choice might also be Continental. Both C. and Pirelli are ligher than competitors, Pirelli is also slightly narrower on same size, where Bridgestone meets the full measure it specifies. Conti in between.

Have these on the rears of a BMW M3, they are fine until they wear and then they become a death trap. Replaced with Goodyear Eagle F1s although louder a much better tire. I've had Continential, Vredesteins, Maxxis on various cars over the years and these P Zeros are so dangerous when wet or worn, I cannot recommend them at all for that reason alone (as others have said too). Wear was average.

This is such a hard wearing tire have done 12k on these tires and they are down to 5mm which is impressive on a Quattro. I am really impressed with the wet grip with these tires on and they corner brilliantly but then again I'm not sure how much of that is down to the Quattro but I don't care these tires are excellent.
