The P Zero may be a 220 but that's only because it's an old, POS tire that wears out too quickly compared to more modern designs. It does not have the same grip level of a Pilot Super Sport or Pilot Sport 4S in the dry or wet. Pirelli's next generation PZ4 tire still can't match the Pilot Super Sport.
Aside from differences between manufacturer ratings, the PSS and PS4S last a lot longer than a tire with their grip level normally would because the inner portion of the tread is actually a harder compound than the outer portion, you do straight-ahead driving on the harder rubber that takes longer to wear out but the softer rubber is there where it needs to be for cornering. This is why PSS has always been surprisingly easy to spin in straight line drag races, it isn't quite as good of a drag racing tire as some others in this category because the full width of the contact patch is not the stickier, softer rubber compound.
I deal with a LOT of GTRs at work, I'm very familiar with the various stock tires they come with and I'll just say the Nismo's tires may be runflats but they are also fairly serious performance tires as far as streetable runflats go...
"SP Sport Maxx GT 600 DSST CTT tires are currently available in three versions: one for 2013 and earlier model year vehicles, another for 2014 and later cars, and the third version, NR1, specifically for the GT-R NISMO. As indicated below, tires for 2014 model year and later cars feature shallower molded tread depths to provide sharper handling and more performance from the beginning, with the NR1 tires featuring the least tread depth to place the highest focus on the extreme dry performance."

Agreed on your tire compound point...plus as per my post - they seem to combine and average out compound numbers.
The Dunlops however, stink. Tires are a major sore spot in the R35 community. Everyone changes over to R888's (and now R888R's) for any real performance needs.
