[QUOTE=mdrums;9124700]I've been tracking my 997's for years in non N spec tires. You do not need N Spec tires...just make sure the size and load rating is with in spec. Michelin Pilot Super Sport tires are an excellent choice for a Porsche.

I know but I want the N for status !

Kind of off topic but I put a set on my 2008 S63 and they are terrific tires. Quiet, handle great for such a heavy car and priced less than the OEM Pirellis. I'll definitely consider them when the time comes to get a fresh pair of shoes for the 911

They are outstanding....compared to the ps2 (before they wore out) the pss feel softer....just as crisp steering.. and have less tire noise on fwy. Cornering is just like with ps2(rails).. only complaint is that the large should blocks make the side walls look much taller...ie higher profile...especially the fronts.

Tim,

Was your car a CPO'ed car you bought from a dealer? I thought I recall as such and thought they would have put new tires on.

gota911

Yes it was a CPO, but the car (and original tires) had only 2,945 when I bought the car, so the tire tread was well within CPO spec. I knew when I bought the car that 1) the car had Pirelli P-zero tires and 2) that I would need new rear tires because it has been my experience that Pirelli tires to wear quickly.

I don´t find the Pzero to be a progressive tire at all, it sticks well, but when it let go, it´s to abrupt and not progressive. Would like to hear your opinion about this question, as you are an experience driver with lots of "proper" miles made on the "proper" place for this cars

I know this thread is old but it relates to my current problem. Last January I ordered two new rear tyres for my 997S (2005 model) I simply wanted them to replace the tyres with the same brand/type and they fitted Michelin Pilot super sports which I assumed were the right tyres.
Then I bring my car to the garage for a service and the service manager says my rear tyres are not N rated. I know nothing about N ratings and don't drive the car that hard anyway so what tyres are on it don't particularly concern me except that they are the right tyres.
The tyres may be great and all that but if they are not N rated and I am involved in some accident my insurance company could say 'you had the wrong tyres on the car - sorry we are not paying out'??

I am not sure about Ireland 's insurance policies, but I don't think think this would be an issue in the U.S.

Your tire installer assumes responsibility -- not you. This is for issues of litigation, though, not insurance. Some installers stick to manufacturer specs whether you like it or not. They've done this to protect themselves.

Insurance policies: Well, they cover your stupidity and bad decisions. Sure, they cover outright accidents inflicted upon you, and they cover your poor choices and poor skills. You decide to drive like an *** in the rain? Covered. You decide to drive in 20 degree temps on Summer tires and rear-end someone when you can't stop in time? Covered.

Record your reckless driving on a mountain road and flip your M3? Covered (true story from the interwebs. Insurance rep said, "Yes, we cover stupidity.")

Now, what your rates might be and whether you get dropped? Well... severely doubt tires will do it. But being a reckless *** changes things.

I was told by my dealer that "N" spec is Porsche approved but by no means required! If the speed rating and load limits are adequate for the car, then the tires are completely acceptable. And MPSS are! DWS are as well.

Alfaguy2

Thanks that puts my mind at rest. I will leave them on until they need replacing but then will return to N rated tyres. Anybody know what the current N rating is for Michelin - N4's have been mentioned here?

Problem here with N rated tyres is that the tyre outlets say they will take ages to arrive and say its just Porsche ripping people off.

But the manager of the specialist Porsche service centre (not a dealer) I go to was pretty unimpressed when he saw the tyres on the back - he is a stickler for detail as I am but perhaps we need to relax a bit.

gota911

Each type of tire gets its own rating starting at N0. As changes to that tire are introduced, teh next verson get the N1 designation... another change moves the designaton to N2... and so on.

PS2 could be N4 but PSS could be at N0.

Hope this helps.

Tim, let me know how they work out for you over time. Those tires are what I'm planning on putting on my car next and I have a feeling my current tires aren't going to last too long......................

FWIW, my friend and p-tech recommended MPSS over the N-Rated tires at my local p-dealer. Apparently some of the N-Rated tires won't balance properly even with weights loaded up on the wheels. Often the p-dealer had to order 2 sets before their road force tire balancer could properly balance enough tires to complete a set. The MPSS, however, have been consistent requiring min. off set weights to properly balance. So far I've been very happy with my MPSS after a year. Far superior to the noisy N-rated P-Zero tires I had previously. BTW, N rated tires do have their place... Porsche requires that p-dealers use N-rated to CPO a car.
