It's time for new tires for my 2008 turbo and I'm stuck between the PSS and the PS2. Reps between tire rack, discount tires.com, and Michelin tell me that the PSS is more advanced, cheaper, have a longer road life. The PS2 is N rated and the PSS is not. My adviser at my local Porsche dealership said that he wouldn't hesitate using the PSS while two guys behind the parts counter say that the N rated tires are a product of research by the Porsche engineers and Michelin and they would use N rated tires.
I would appreciate some input.

 

I'm debuting the same but likely to go with the pss. How many times are we really going over 186mph. Shhh ok don't answer that lol

 

My research has revealed that the pilot sport 4 is replacing the ps2. It was just made available in March. I think that's the way to go if you're willing to ignore the N rating.

 

The new p4s is replacing the pss and is a dual compound design. It is suppose to be fantastic and from the people that went to the launch and drive past and ps4 back to back on the same car they said is was a noticeable improvement. That's an improvement on basically the best all around summer performance tire made so its saying a lot.

I'd look into p4s. Ps2 is old tech now and as far as I know are being completely phased out of production

 

Just got the new PS4S mounted today. They are nice! Just like PSS but they're supposed to have longer thread life.

 

I'm going to pull the trigger. Where did you purchase your PS4s?

 

tirerack.com has them in stock.

 

Getting the new Michelin PS4s mounted this Thursday. Will report back on how it performs...research suggests this is the new "it" tire for 80/20 (street/track) use.

 

From this post I end up doing the 4s too. Find it the cheapest at tirecrawler.com, I'm not associated with them

 

I would certainly not be overly concerned with the N rating. There are many very good tires available without that rating, and at least 1 tire (Pirelli) that is N rated and, in my opinion, is a very poor tire. The PSS has an excellent rep, and the PS4 is said to be even better.

 

Got PS4 mounted over the weekend. Awesome tires and checks all my criterias and more

 

Still waiting to try out these PS4's, my car has been at the dealership for a week. They're having difficulty balancing them. The tire rack has sent a second set and one of those tires has a road force balance number of 51! (acceptable is below 26). Tire rack says the problem is the balancer (and poss. need for calibration), the dealership says the tires are a problem. Hopefully they calibrate the machine today (or sometime before my car is an antique!)

 

It's most likely their equipment
