That's one of the problems with the P Zeros, there is so many models (OE and Aftermarket) that you dont even know whats going on... but one thing is for sure, they dont last long. See the Tire Rack reviews on the various models, that's the number one complaint, whether it be the 220 or the 280 treadwear rating. (Thas also the main complaint of most performance Bridgestone tires as well...)
For example, Pirelli gives the All Season Plus tires I'm on right now a treadwear rating of 500 (w/ 50k mi warranty), I am just past 21k mi on them and I don't think they are making it that far past 25k..... I knew it couldnt be, because since the day I mounted them they felt really sticky, pretty much like to OE Potenzas…. 500 rating is like a grand touring tire..... The P Zero AS+ is even more summer biased than the Conti DWS, I got them because of that, the wear rating & TR testing rolling resistance. I lived in Delaware, I expected maybe half a dozen snow days, so snow performance was secondary....
You cant really compare treadwear ratings between manufactures as they all have their own formula.... but between Pirellis, if you consider that 500 rating from my tire, expect 15-20k mi from the 220/280 rated P Zeros.... which is about right if you look at TR reviews....
edit: Also what
@EpicTech noted about the dry/wet handing makes sense, Conti themselves rate their EC 02 on par with the PS4S in the dry, but slightly below in wet performance....
