Does any one know if there is a difference between Perelli P Zero Rosso Aysmetrico N spec Vs Perelli P Zero Rosso Aysmetrico? Are they the same tire? Why is the N spec 80 bucks more expensive?

From the Tire Rack website:

"It is also important to know that while Porsche N-specification tires have been fine tuned to meet the specific performance needs of Porsche vehicles, the tire manufacturers may also build other tires featuring the same name, size and speed rating as the N-specification tires for non-Porsche applications. These tires may not be branded with the Porsche N-specification because they do not share the same internal construction and/or tread compound ingredients as the N-specification tires. Using tires that are not N-specific is not recommended and mixing them with other N-specification tires is not permissible."

So, because it's "Porsche" approved, it's going to cost more. They will never divulge whether it's actually the same tire. Same with the coolant, etc...

Regards, Maurice.

N coded tyres have stiffer side walls than the same non coded tyres, easily perceptible at the higher wall/threat ratio, for example 987 OEM 17" rear tyres.

I have Goodyear Eagle F1 GSD3's on my 996 C4. They were cheaper than N rated tyres but they're not as good. They tend to feel less stable when cornering at speed compared to the P Zeroes I had before which would tend to support the sidewall strength theory.

On the plus side they seem to be lasting forever (in Porsche terms). 7,000 miles on the rears and still 5-6mm of tread, fronts have 7mm at 8,000 !!

Having said that I'll probably try Conti's next time around. Harder wearing than P Zeroes but still N rated. I'd spend the extra cash if I were you

I went with the Sumitomo HTR Z II's $550.00 delivered from tirerack, I asked around, my buddy has them on his Boxster, a guy at work has them on his 996. I do not pitch my car into corners, mostly just cruise up and down the coast, it is a daily driver, I just couldn't pay 2X for N on the side of the tire.
