I drive a 2005 Mercedes C55 AMG Kleemann S7 (over 450rwhq) - This by far, bar none is the best tire I have ever owned. The grip that this provides over other tires I have had on the car is biblical in comparison. Either on the autocross track (gritty surface to blacktop), this tire grips. I guess the best explination would be highlighted when I am on the bleeding edge of grip around a turn...at the point that most tires would break loose, these tires just hold on. I cant tell you how many times I have thought to myself, man, how the -------- did those tires grip like that...
As impressive as they are on a nice summer dry day, they are equally impressive in the rain. If you have a car with traction problems (yes you cobra's, vettes, merc's) ...higher TQ cars ... these are the tires for you. 10+ ...if this was the bar, nothing would ever be up to standard.

Initial Review, 1,000 Miles on Tires
November 03, 2008

This is an awesome tire. I replaced Conti SportContact 2's with a pair of these up front. The Conti's were good, but these are great. Quieter, smoother, stickier. Responsive steering, great cornering, and great wet traction. I have read complaints here that the treadlife is short, but I just got them so I don't know. I have noticed that they jump around a little on grooved concrete, but that will happen with any tire that has large continuous grooves in the center.
I purchased the 'Mercedes Spec' version of PS2's, and they seem to be a great match for my C32 AMG. They are sooooo quiet.
I'm very happy, and will definitely purchase again if I get more than 15K miles out of them. We'll see.

Follow-up Review, 15,000 Miles on Tires
May 20, 2009

I can't say enough about this tire. After of 12000+ miles on them, they have not worn like others complained about. They look almost new.
They grip great, they are so quiet, and thankfully, they haven't worn quickly.
I gave it 10's across the board because in 25 years of driving, I have never driven on better tires.

Follow-up Review, 22,000 Miles on Tires
November 29, 2009

I got 22K out of the tires up front. The shoulders are worn to the belts, but there is still some tread left in the middle. I don't think most people will take them this far; most would have replaced by now. That's not from under-inflation, but from very spirited cornering. The confidence these tires give is so satisfying, but yes the tread wear is quick. The last few thousand miles, the noise got a little louder, but still less then any other tire I've ridden. If you can afford them, you will not be disappointed.
Having said that, I am going to try the Goodyear F1's which are supposed to be on par with the PS2's, yet a little cheaper, and coincidently on sale right now. :)

This is by far the best performance tire that can be purchaced on the market. I have had a tire from almost every manufacturer and none compare. Excellent traction on dry pavement and the tire just blasts through deep puddles on the highway with little to no hydroplaning. Being an aggesive driver I would definatly recommend this tire to anyone that wants good performance. Expensive but totaly worth it.

I replaced the OEM runflats with a set of PS2s and the difference is absolutly amazing. Everything is better, the PS2s are more comfortible, quieter, and have better cornering.
I autoxed all last year and even with 14-20 hard launches a weekend for 2 months my rears still had tread when I took them off at 18000 miles. Absolutly amazing out of a summer performance tire. They also stood up to several 700 mile roadtrips, with a lot of fun along the way.
I will definently be mounting these again come April.

The Bridgestone Potenza tires that were original equipment on my 2005 Infiniti G-35 Coupe (19-inch wheels) became incredibly noisy after the first few thousand miles.

It was so bad I wonder who at Nissan/Infiniti was responsible for pairing those tires with this car. I complained to the dealer on a few occasions. I thought the wheel bearings were going out, which I understand is a common complaint, and was told it was the tread design of the Potenzas that was responsible. After waiting far too long, I finally broke down and bought a set of PS-2s. The PS-2s are quiet and react much more predictably than the Bridgestones.

If they last even 20,000 miles it will be worth it. Although I don't know how long they will last, I would still recommend the PS-2s to any Infiniti owner who is dissatisfied with the Potenzas.

Just got the PS2's for my 2002 BMW M3 and what a difference. I had the Michelin Pilot Sports and were happy with them but decided to try to the PS2's. As I was driving away from the tire place I could immediately notice that these tires were dramatically quieter than the regular Pilot Sports. They take harsh roads a little easier and handling is just as good if not better. Tread life is never good on the M's, I got 25K out of the Pilot Sports and I'll guess we'll have to wait and see what we get on these.

I just arrived back home from visiting my cousin in Munich and we drove to Spain to spend some time at his holiday house. The drive to Spain was very entertaining. He drives a Brabus tuned Mercedes with a 650hp V12 and he uses the new Michelin PS2 tires. From Munich we encountered alot of cold and wet driving conditions and the tires exhibited very impressive traction under those condtions. With temperatures only a few degrees above freezing, we were still able to take corners at break neck speeds, and accelerate hard with only minimal tire spin. As we continued on our trip the tires showed that they are very suitable for long distance driving by being smooth and quiet. Even on the rain soaked autobahn the tires were easily capable of driving safely at speeds over 260kph. But it should be noted that German highways are built with such high quality standards which makes it possible to drive safely at such high speeds.

As we got closer to Spain, the weather began to improve and temperatures began to rise, the tires grip also improved. Hard cornering is no problem for these tires. Accelerating to 100 kph in well under 4 seconds seemed too easy. On one stretch of highway in Spain we got the Benze up to 320 kph and again the car remained very stable and smooth. Never in my life have I driven so fast and at those speeds the scenery whips by so fast that your brain almost does not have time to realize what just passed by. A tire has to be built very good to handle such speeds and its understanding why the Michelin PS2's are expensive. All that R&D does not come cheap, and the tires are built in France where factory workers are paid considerably more than in the U.S. and Asia.

So after that experience, when my Kumho's wear out (also great tires) I am getting me a set of PS2's! Is it any wonder these tires come standard equipment on some of the most amazing super cars on the planet. Including the new Bugatti Veyron with 1000hp, 0-100 in 2.6 seconds and a top speed of 406kph!

Fronts lasted 30K
Rears Lasted 60k

Driving style: Very Gentle

Excellent tire highly recommended works superbly in all conditions except snow, but then again its a summer tire and not designed for snow use.

Simply superb best tires I have ever used!!!!!!!!

When it comes to tires I have narrowed them down to:

Michelin PS2, Continental CSC3, Bridgestone RE050A

Depending on which is the best value at the time all the above tires give excellent grip in the dry and wet and feel very progressive on the limits.

In the dry I think the Michelins just shade the Bridgestone's, Continentals are best for preventing aquaplaning in a bend or straight line.

The Michelins are best in the wet too with again Bridgestone just behind in second. So all three are superb tires but I find the Michelins last the longest with Bridgestone 2nd and the Continentals 3rd.

In terms of value for money I would say the Continentals and Bridgestone are good with the Michelin being pricey and in 3rd place.

I was reluctant to pay about ?30 more per corner for these tires compared to the usual suspects Conti's and bridgestones. And due to the S3 quattro chassis I got awesome grip anyhow and was content with the tires already used.

A friend convinced me to try the Michelin PS2 and since then I won't fit another tire. Dry grip and cornering is excellent, wet grip and cornering excellent. Dry and wet braking these tires really do stop the car and eat into the ground when doing so giving you so much confidence and grip.

They are very progressive on the limit and the road feedback is excellent too. I am happy with the wear rates from these as they are Ultra High Performance but with my spirited driving style these are a good buy. they grip from the first mile superbly right down to about 2mm and under 2mm they just go very hard and maybe lose about 10% of the performance but that would be the same with any tire under 2mm coming close to 1.6mm.

I am so impressed with these tires, they give the car a good smooth balance and have lasted almost 40k.

I have never thrashed any of my cars and like to drive smooth and be gentle, however on some A roads these tires have gripped really well and give a nice firm feel.

The only drawback is that they are expensive up to 30% more than the competition.
