Porsche N1 compound (tyres - again!)

I suspect this is a topic that has probably been discussed to death on this forum over the years, but with me being a new member please be patient!

I have a real mixed bag of partly worns at the moment since changing my original wheels to Boxter 17" wheels. They are currently a pair of (well worn/barely leagal) 205/55/17 Pirelli P Zeros on the front and a mix of Continental and Falken(?) 255/40/17 on the back which have a good 8mm of tread or so on them.

I need to change the fronts soon and would like to go for the Continentals since I had them on my previous car which I used to abuse on the local roundabouts and found them to be a great all-round tyre with good wear resistance (they lasted me a good 50k miles and were still legal when I sold the car on and got my 944 turbo) so would like to go for Conti's again. This also has the advantage that I will only need to replace one rear tyre to get a full set of same brand tyres, but I am open to any advice on other tyres.

However i've heard about the Porsche N1 compound so:-
[sm=spanner1.gif] Is it worth specifying the N1 compound and do all main brand tyre manufacturers make N1 compound tyres?
[sm=spanner2.gif] Or is it not really worth worrying about since I probably wont notice the benefit on the road?
[sm=spanner3.gif] And how will I tell if my current Conti is an N1 compound or standard compound?

Thanks in advance for the advice. I must say i've found the forum a great source of general info since using it and feel I have got to know the 944 reasonably well in the short space of time I've owned it. I look forward to being able to getting some experience under my belt and contributing to the forum a bit more.

Cheers, Scott.

Q: However i've heard about the Porsche N1 compound so:-

A: N1 is old hat now, probably equates to a tyre that could be ten years old -I think they are upto N4 now

Q: Or is it not really worth worrying about since I probably won't notice the benefit on the road?

A: N rated tyres are homologated by Porsche for Porsches. AFAIK, the only difference is a stiffened sidewall. Since your car may not have originally been specified with N rated tyres, it shouldn't be problem, but......However, with matching tyres and N ratings, I'm sure that you WILL notice the difference

Q: And how will I tell if my current Conti is an N1 compound or standard compound?

A: It should be printed on the side....

Now, this is the important bit, read my lips...do NOT mix tyre makes or N ratings on your Porsche -end of story.

Have fun!!

Nearly - but it is slightly more complicated than that:

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.


You can find out all about N-spec tyres --> HERE <--
This link is also available in the --> General FAQ <--, where more tyre info - including Porsche tests, can be found. However, as stated above, it does not really apply to 944's.

Same axle - don't mix, same car but in pairs across the axles I don't see is a problem.
 
Me Again.

Always seem to be commenting on tyres!

Wouldn't personally mix tyres front or rear (reasonshavealreadybeendonetodeath etc....)

Also,

Here is a great article on N spec tyres.

I guess this means you definately can't mix N and non-N, but I would say if N means Porsche approved then you might as well use them!

Thanks to Mark for the differences in the N ratings - something I didn't know (which happens alot according to my Wife!)
 
Conti's are now N2 I believe, at least for 968 17" wheels. I had to change both my rears for N2s as I couldn't find one N1 anywhere. My fronts are not even N rated, so a previous owner has obviously fitted the wrong tyres at some point.
