I'm really not sure that the PS2's are significantly better than competing tires. Other tires do just about as well in the independent tests. The PS2's are a good tire, no doubt, but there are others that are as good, and those others tend to be better value for money. I had PS2's on my 2007 S Coupe, and personally I was actually a little underwhelmed.

 

Look for posts from Zoomzoommo. He has a set of the RE-11 and he's posted very positive feedback and a video. The RE-11 will most probably be my next tire.

 

One thing to keep in mind regarding tghe RE11's, they aren't equal in load rating and speed rating of the OEM tire. It is probably inconsequential but just wanted to throw that out there.

while tire shopping this morning I found out the same thing and I actually think it is important, maybe not the top speed rating (well, but even that for the occassional empty road in the middle of nowhere), but the load rating and the stress on the tire.

I decided to go with Pirellis PZero Rosso 305/30 19" instead, saved about $500 on the Michelins I considered and had the best test result at a recent test at Sport Auto (done on a Techart 911S - http://www.sportauto-online.de/somme...2-1037240.html - Google will translate it)

 

I agree with you actually and it is the reason why I wouldn't get these tires. However, a few have tracked these tires (not AutoX) and they had good results. Did you go with the Nspec Pirelli's? I want to know how you saved $500 as the price I see for the Nspec are about the same as the PS2s.

I got PZero Rosso Assimetrica 305/30ZR19XL 102Y N1 (I think the N1 refers to your Nspec, right?) - http://www.discounttire.com/dtcs/tir...89123&pc=41030

Total price installed including tax for all four tires came to $1750 vs $2137 for the Michelins (and my car has currently Michelins that are terrible - purely because of age (just bought the car, 2006 with 26000 miles and it had the original tires, pretty much shot!!!!).

 

Tirerack has the set of 4 delivered for around the same price at $1760 delivered to my door. The Pirellis were $100 cheaper...

I like the Pirellis, I know I'm a minority in this opinion but as far as performance goes I think they are up there with the PS2s. Its just when they age they get noisy.

Dave

 

Dave - the price of $1750 is installed, all in, i.e. mounting, balance, warranty, rotation (lifetime), sales tax etc.

 

Not bad at all..I think you will like the Pirellis. My rears went out at around 15k miles and was deciding to go with a whole set of 4 PS2s or just 2 new Pirellis in the 305 size, I went back with the Pirellis.

Good job..

Dave

 

Well, will send an update next week with a report on the new tires, both the new size (305&245 as opposed to the current 295&235) as well as report on the Pirellis ....

 

Stick with the Michelin Pilot Sports. or get PS2 Cups.

If you go with Bridgestone, use Bridgestone Potenza RE050A (Max Performance Summer) They are N0 (Porsche) rated.

 

What does "N spec" mean? Also, what are N1 and N0 ratings?

Thanks

 

Here you go..

stick with the 305's they are a great tire, if you are looking for a excellent tire, ps2 are the way to go, on the street and for the highway. Especially if you drive everyday, you get better wear than the other choice, which would be pirelli? nitto idk about them, i never had those on a car b4. good luck with everything though.

 

Porsche designs and manufacturers some of the highest performance vehicles in the world. Because of the integral role that tires play in vehicle performance, Porsche has integrated tire development throughout their process of vehicle development. To be an Original Equipment tire provider on a Porsche vehicle or be approved by Porsche for the replacement market requires the joint product development efforts of the tire engineers working alongside the Porsche vehicle engineers.
The focus in recent radial tire development for Porsche vehicles has primarily included optimum handling on dry surfaces and the safest possible behavior on wet surfaces, even at high speeds. Tires developed by various manufacturers, in concert with Porsche, offer a specific set of wet grip properties which few, if any, other automobile manufacturers demand in equal measure from the tires they use on their vehicles.
Tires may be specified for a particular vehicle or range of vehicles and must successfully pass the tire company's laboratory tests to assure that they would be capable of adequately supporting the Porsche vehicle while allowing it to reach its top speed on the German Autobahn. Additional laboratory, test track and race track tests are conducted to confirm that the prototype tires meet Porsche's noise, hydroplaning and handling requirements. Prototype tires will also be evaluated to assess their high-speed durability, uniformity and serviceability. Upon test completion, the tires will be released for production.
Production tires that have passed all of the tests and received the engineering department's release can be branded with an N-specification. The N-specification brandings include: N-0 (N-zero), N-1, N-2, N-3 or N-4. These markings on a tire's sidewall clearly identify them as approved by Porsche for their vehicles. The N-0 marking is assigned to the first approved version of a tire design. As that design is refined externally or internally, the later significant evolutions will result in a new generation of the tire to be branded with N-1, N-2, N-3, etc., in succession. When a completely new tire design is approved, it receives the N-0 branding and the succession begins again.
It is recommended that only matching tires be used on Porsche vehicles. Since many Porsche vehicles are fitted with differently sized tires on their front and rear axles, this means matching the tire make, tire type and N-specification. If a vehicle was originally delivered with N-specification tires that have been discontinued and are no longer available, it is recommended to change all four tires to a higher numeric N-specification design appropriate for that vehicle. Mixed tire types are not permissible.
