I bought these for my old Honda Civic Type R and am now running them on my slower Civic 1.8 Sport.
The positives :
They grip very well in dry from standstill, and they are outstanding in the wet when driven reasonable. The P Zero design looks really classy.
The negatives :
1) I bought them as a very sporty tire, the old tires on my Volk summerwheels where Neova Advan AD07, and as a true sports tire the P Zero really let me down. They do not give me any sort of road feedback you might expect from such a premium tire brand.
2) They are quite noisy and even after 25000 miles they are still as noisy as when they where new.
I could easily live with the tire noise (not nearly as bad as the Yoko' AD07) if the P Zero provided a thrilling feedback but they don't.
I think that the P Zero tire will probably benefit from being mounted on a bigger wheel then my 17x7.5 inch, so it can get a lower profile. Somewhere between 40 and 35 and possible stretched a bit.
Overall :
The tire feels secure, with great dry and wet grip but it doesn't deliver any thrilling sensation and it is an unnecessary noisy companion for daily commute. I will definitely not buy this tire again and am thinking more along the lines of Yokohamas Advan Sport V105 or Michelins Pilot Sport 4 or maybe the Sport Cup 2.
