Summary: I bought this tyre as Jaguar use it as an OEM tyre on the F-type, I was not disappointed, I have a matching set all round now and have driven a lot of road miles and done one track day on them. They have performed very well in all conditions and with some slight pressure adjustments they performed excellently on track, even with large amounts of oversteer!
Summary: 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 tyre, grips, holds, responses and performs. Bare in mind I drive a Volvo which is among the worst cars made.
Summary: 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 tyre. 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.
Summary: This is such a hard wearing tyre have done 12k on these tyres and they are down to 5mm which is impressive on a Quattro. I am really impressed with the wet grip with these tyres 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 tyres are excellent.
