I'm looking for some advice and I hope someone here can help.
I need two new front tryes for my 944. It's fitted with a set of Boxster 17" alloys wearing 205 x 50 x 17 N2 PZero Direzionale tyres up front with 255 x 40 x 17 N2 PZero Assimmetrico rears.
Anyway I've been phoning around this morning and am told you cant get these any longer and that I need to fit PZero Rosso N3's...................But! I shouldn't mix them with the PZero Assimmetrico N2 that I have on the rear.
Anyone got any advice as to what I should fit? Does anyone else have the same set up on their 944? and what is wrong with fitting N3 on the front and N2 on the rear?

Anyone help?
 
www.kwik-fit.com have them listed.....

Oh, and I just had new rear 18's on mine which pirelli don't have in stock (they aparrently run down 'cos of the xmas break). Of course the bigger boys have them in a warehouse. Kwik fit were actually cheapest on mine (in fact they worked out checper than a trade price!)
 
Thanks for that, Gave quick fit a call and they say the same, N2 PZero is end of line and they cant get them. Good and bad news on the N3's though, I can fit them as long as I dont mix N2 and N3 on the same axle.......bad news is they cant get them till the end of January!
 
Seeing as you are up in Motherwell, have you given Jim Dickson a call (01236 720205), he may have some more luck with the tyres you are looking for? Comes highly recommended by a number of the Scottish Porsche owners?
 
Oh well. you can't have everything!

Have you tried a few of the other large ones? Hi-Q, ATS etc etc. I think Hi-Q have a price match scheme, and they may have a pair knocking around the back of their shop. (although ATS were incredibly incompetent for me and wondered why they couldn't get mine in N1 when I clearly told them it was an N3).

IIRC, the Nx rating is updated once in a while, so the larger the number, the later the approval. I'm not sure on that though. So I don't see a reason why you shouldn't mix N2 and N3's on different axles either. to do it on the same axle may well mean that the tyres have actually been updated over time and they wouldn't be matching exactly. (not good!)
 
I think the rules are don't mix on the same axel but you can between front and rear. I think that is a good rule of thumb for tyres and suspension component on any car though.
 
Just be aware that the latest N ratings will NEVER EVER have never been tested on your 944 so there is no point busting a gut trying to find them. They will have been tested and approved for the latest 911 and Boxsters, but they are totally different cars to ours.

Personally, I would fit PZero Direzionales to the front but not worry about the N rating as long as they are the same tyre across the axle.
 
Thanks for all your help with this, the latest is that the guy from Kwikfit has called back to tell me he has managed to find two PZero Rosso N3.
I'm having them fitted tomorrow (£292 fitted). I agree that because they are being fitted to a 944 that the N rating is meaning less I just wasn't sure what to fit.
I'll let you all know how I get on tomorrow.

Thanks again.

Oops - just spotted this.

You'll get the same tyres from Mytyres for £119.60 each, delivered to your door. See HERE.

Your local tyre place will probably fit them - if not Drivers in Glasgow will do fit, valve & balance (filled with nitrogen-rich mix) for £7.50 per tyre.

If you can wait a few days for delivery, then it'll cost you around £250 for the pair.

Of course, if you've just paid £290+ , then pretend you didn't read this. [&:]
 
mik_ok,
I did try MyTyres and Blackcircles and was told by both that they couldn't get any PZero's only PZero Rosso's and they wouldn't be here until the middle of January.

Both fronts are well worn but legal so I could have waited but for the nail I picked up on Tuesday night!

Thanks again, and have a good Christmas and New Year!

 
Ach - nothing lost then.

Turnaround is always the downside with the interweb tyre places ~ if you don't have the luxury of time to wait, they're useless.
 
New tyre's fitted today, The Rosso's side wall looks a bit different from the PZero's, steering feels a bit sharper (think any fresh tyres would feel better tho). Apart from that round and black like the old ones.......oh! and N3 instead of N2, that must mean they are better doesnt it?
I asked the guy at KwikFit what the N rating meant. He didn't have a clue either!

Have a Merry Christmas everyone and thanks again for the help

It's a debate, but IMO as the N tyres came way after the 944 (OK maybe the originals didn't - I seem to recall someone said they just overlapped. but N2 or N3 certainly didn't) and the rating relates to cars with engines in the back or the middle then it's pointless.
 
That's what I suspected, Fen, thanks. The current Michelins are N2 rated - perhaps the previous owner buckled to an over-zealous kwik fit fitter. Normal ones it is, then.
 
Do insurers demand the use of N-rated tyres or is it factory/commercial hype only ?
 
Interesting point - I suppose they could make that argument on a later car but, as Fen says, the N rating was not OE on the 944 anyway. I've just looked at my manual and there is no reference to N marked tyres being a requirement. Perhaps it does say that in a 996/7 manual and then they might be able to argue it.
 
The N rating means that the tyre has been tested & passed a certain standard set by Porsche, so you could think of it as exceeding a certain quality level for sportscars that weight about a tonne and a half.

I've always put N-rated tyres on my Porsches & I guess I've paid a little extra for peace of mind. There are certainly tyres that fit that are suitable & may be better value for money.

While the rating didn't start until after my car was made I don't see that my car's tyre requirements are really any different from that of a Boxter (ie a later car with 16" wheels). The weight, top speed & likely use are compatable.

The number after the N isn't significant, it's just the revision number of the tyre construction/compound for that manufacturer, so an N3 from one company may be a later revision (and therefore presumably better in some way) than an N4 from another.

One thing it does seem to virtually guarantee though - if you specify N-rated tyres the fitter will probably have to order them (unless it's a specialist).

Click to expand...

Because of course Michelins etc. without N-rating are death traps...

Tyres have load, wear, speed etc. ratings and EC compliance to cover all the stuff that matters regarding the weight and top speed of a car without any manufacturer specific stuff. N-rating can mean a tyre comes out a different width than others in the same nominal size. As I said buy them if you want as it won;t do any harm but they are totally unnecessary.
