Performance Tire Comparison
My Original Eagle runflats are pretty well worn out and am looking for a replacement set(all 4)
I had ARH headers, x-pipe, and Corsa Sport exhaust installed and now the rubber on these tires is disappearing fast.
I am serious about buying runflats again for safety reasons but...
Any advice would be greatly appreciated!

Runflats are safer? I think runflats are a crock. You can drive 50 miles with no air, but then the tire is destroyed and you need to replace a $300 tire. Get a ContiComfortKit and buy some non-runflats. You can drive way further than 50 miles on a sealed tire and if the sealant destroys the tire sensor, you need a new $60 tire sensor then.
The ride quality is remarkably better with non-runflats and you have more high performance tire options. A popular street tire with the autocrossers around here is the Bridgestone Potenza RE-11. I run Michelin PS/2s in the summer (got the set at half price) and Pirelli Sottozeros in the cold.

When i was wondering whether to keep runflats on our C5, I ran across several posts by people who had blowouts (hit a sharp piece of metal, etc) at speeds over 100 and the most common reaction was that they didn't know the tire was flat until the car started throwing messages at them. That's a safety issue.
Sometimes a flat happens in the middle of a long tunnel or bridge, where stopping is dangerous, car control can be a problem if you keep driving even if you're wiling to destroy your wheel and your fender. That's a safety issue.
Bill Cosby's son was killed during a robbery as he was changing a flat tire. That's a safety issue.
There are disadvantages to runflats, as you point out. But oveall, they are safer.
BTW, the NCCC 2009 autocross champions for our region, man and woman, both used Michelins PS2 ZP runflats to win. They previously had the non-runflat version of that tire on their car but switched to the runflat, said it performed better.

Safety can be a "mind perception" thing, or it can be real. You choose. But if the examples above aren't "safety" then that is ignoring real-life situations. I've experienced a few of the examples; for those reasons and more, I appreciate the reality of runflats.

Runflats are indeed safer, your other points don't addres that.

Run flats give you the choice to drive on and not stop say in a tunnel, on a bridge, middle of a construction zone (where a lot of flats happen) or in a bad neighborhood. I personally don't want to be out of my bright AO C6 in the middle of a bad neighborhood. I took a wrong turn off I-80 into Gary, IN and I swore I saw 3 drug deals and most of the locals were packing. That was in my Impala which was clearly the nicest car around.

Pick any tire and you can find a thread stating it's the best thing since sliced bread. Everybody has their favorite.
They're safer for the reasons stated above. Imagine trying to plug one on a narrow road at night in the rain.

I just replaced the original goodyear supercars on my 2005 coupe with Michelin Pilot sport PS2 ZP tires and they are great. They are much quieter and much smoother over bumps. I know that there will always be an improvement with new tires but I feel that the Michelins are superior to the Goodyears.

Sorry kids, I bought a performance car for performance.
Once I ditched those god awful runflats and put on good tires (my first mod) I started to realize what a fantastic and responsive automobile the Corvette really is.
Runflats are heavy, floppy, unresponsive, noisy and overly expensive. If you haven't driven a Corvette with good, performance tires you don't know what you're missing, but I guess as they say, ignorance is bliss.

Tirerack has the ZP version of the PS2 as the same weight as the regular PS2. A lot of people tend to compare tires of different categories. I bet if they did a comparision of the PS2 ZP to the regular PS2 there wouldn't be a difference. If GM could get a better time around The Ring with the ZR1 on non-runflat PS2s they would have done it.
