For real life treadwear experience, all I can tell you is I have done 20000KMs, 7 track days, and about 10 autocrosses on my PSS on my e36 m3 and I'd bet I have 60% tread left.
Owner reviews for tires
Ventus V12 EVO2 is the sleeper tire in this category. A few buddies run them, they are a lot like the PSS, in that they are a summer performance tire with consideration to tire life. But at an even lower cost.
Goodyear Supercar 3 needs the most heat. The stickiest of the three. Good trackable street tire.
I'm 2 months into my fire hawk indy 500's...I CANNOT believe they're so cheap. I'm not expecting much more than 30k miles, but they grip exceptionally well even when I expected understeer, the car maintained its line. They're easily the stiffest tire I've ever owned. That can be a good and bad thing.
So far I haven't really pushed them, and I don't do much more than just some very quick backroad driving and highway miles. I've had them for almost a month (even in below / near freezing) and haven't had any issues unless there was snow on the road (obviously since they're summer tires).
I have had the Continental DW tires for between 25-30k miles. I have nothing but high praise for my DW's. Great wet and dry grip, not very loud, I've got nearly 30k miles on them and they still have plenty of tread left... I would guess another 10k. Predictable as well. I've literally tried to break them loose in rain while driving my CC, and it's very hard to do so. I've even slammed on the brakes in medium rain to try to slide from 35-40mph, and they just gripped to a stop. I love them... my wife even appreciates how quiet they are. I will point out though that most of my driving is pretty calm...It's rare that I really push them, but I have, and they were great. I'll be buying the Conti's when I get my new R in a few weeks. Edit: Let me also point out that I use mine year round. Even in the winter they've been great. I live near Nashville, TN...not much snow, but plenty of below freezing air.
I have run both .the Continental and Michelin you mention. I think the Continentals last longer and can take more abuse--at least they did on my STI
I have been using the Continental ExtremeContact Sport Plus for 2,000 miles. They are a very pleasant-handling tire (quasi-aggressive street driving). Predictable performance on dry, wet, and snow/ice covered pavement. Turn-in/steering response is similar to the Dunlop Direzza ZII Star Spec, which I previously used for both street and autocross.
We have a set of Sunny tires on our 98 Cavalier 4dr auto. (Used as summer only). Also a dedicated set of Cooper winter tires. As a summer only tire they have been fine for the last ~60,000km+ and the only reason for buying them is they were cheap, the car is old and getting pretty high in mileage. Wasn't sure how long it would last to be honest. It has surprised me and I figure the next set I buy will be a brand name all season for the summer only to have the car inevitably crap out shortly after.
I run Conti DWSes on my A3 and I think they're abysmal with anything more than an inch of slush on the roads. More than that, once the temps get below 40 I can definitely sense them losing their grip. I haven't been overly thrilled with the Contis and don't think I'll buy them again.
