i have heard that the hankook is the real bargain in performance tires
much of this is opinion, many people say the PS2 is the best tire on the market
my stock bridgestones are fine, but i can say that the PS2s have a better ride...my friends turbo w/ 20s and PS2s rides softer and quieter than my 19s w/ Bridgestones
while i am not ready yet for a new set of tires, i am going to consider the hankook

wow,
really shocking, I was thinking about buying the RE11's when my pirellis wear out but now they're off my list.
Can you make a really good point. Shaving pounds off of unsprung weight is probably the most cost effective way to improve the performance of your car. I've read that multiplier of rotational mass is somewhere between 8-10, ie loosing 20 pounds of rotational mass is the equivalent of losing 160-200 pounds of sprung weight. Trying losing 150 pounds by replacing parts with carbon fiber!
Personally, I do think that gaining our losing 4 pounds per wheel would be noticeable. Think about how much money people will spend to eek out a few more hp with an exhaust, cats, etc. And hp gain only helps with acceleration. Decreasing rotating unsprung weight improves acceleration, braking and cornering.

While it's not the end of the world to use other tires (and I don't mean to be critical of those who do so), I would stay with Porsche specific, N rated Michelin Pilot Sport N1 (what I would recommend for you to try), or Pirelli PZero. Or... if you want to be adventurous and are not driving the car in the rain or snow, move to the r compound tires, either Pirelli Corsa or Michelin Cup. (There is a thread on this somewhere, but the N rating has to do with tire construction made for the specific rear engine rear heavy configuration of the 911. Anyone corrects me as needed.)
On the tirerack site below, check out the weights of the tires, (as Chris/E55AMG mentioned) some of the tires like the RE-11 are REALLY heavy, and tire being the outer border, it's the worst place that you want to gain weight.
This topic has been discussed many times before, but to make the long story short, moment of inertia is worse the further out you are in the wheel. Heaviness at the rim periphery will affect braking, acceleration, and steering much worse than if the weight is towards center. Whether a driver could feel it or not could be debated, but the effect is there.
Michelin Cup: front 20 rear 27
Pirelli Corsa: front 21 rear 26
Bridgestone Potenza RE-11: front 27 rear 32
(A near 30% weight gain in front!!)

My OEM Pirelli P Zero tires are due to be replaced. I always felt that they were noisy. They have developed some cupping too which is a little strange. They have always been balanced and pressure maintained and never used at the track. They only have about 10,000 miles on them but the cupping has caused a highway hum that is intolerable so I must replace them.

Alcyon, thanks. I am going to use Pirelli Corsa next.

However,If you don't drive your car very often, Corsa system is probably the best choice.

Michelins PS2 are not available
I need to buy a set for the Beast TT 17k miles just making too much noise. What happened with Michelin, the fronts are being sold but no rears? Are we being set up for another price hike?
