o no tyres again! N numbers
Discussion
what do the N numbers mean on tyers, (sorry dogsharks i carnt spel IIIther) is it just consecutive numbers or does it refer to the compound. I'll need to change my tyres soon and was considering Contisport 2's. However i'm an old fart and my priority is for a a 'quiet' tyre with lots of tread pattern that i dont have to change for a long time. Now looking at So2's but cannot find any info on Bridgestone web site. Car 944 S2. Any comments?
I think you will have trouble getting SO2s now since they are almost extinct and have been replaced sith S03s.
The S03s have hard sidewalls and so a harder ride. This is more apparent on light cars (not sure of 944S2 wieght). Running a couple of PSI under though solves the problem and the ride is as good as So2s like this.
I dont speak from experience but have asked the questions myself as am about to change from SO2s to S03s.
The alternative is to go for "Toyo Proxes T1S" which have the same soft sidewall as the S02s and so give the same ride.
Hope that helps.

So2 are available off the shelf if you look very hard.
If you don't want to look very hard,,go to the pistonheads oilypages and you will find more than 3 companies advertising who can get them the same day,,, you then enter the silly game of playing them off against each other and end up getting the tyres at a bargain price!
Edited to say that is my recent experience rather than speculation.

N Numbered tyres are Porsche approved tyres. You can fit non Porsche approved if you so wish. The various numbers refer to compound changes and in the case of the SO2 N3 to N4 (strictly SO2AZ) a tread pattern change as well. You can have different N numbers on different axles but not on the same axle.
If you want ultimate grip (IMO) go for the SO2's but the compromise is they don't last long. I get (got) about 10K of my rears. Some quote around 5K! If you are after a long lasting tyre I would advise looking else where.
Jeff's tyres (Warrington) had some last week if you want to try them 01925 247560.

You'll get SO2's & most others from here at a good price.
Toyo's seem to be better value but arn't N rated

Did they just stop doing SO2s in certain sizes then?
I cant find 205/55/15 and 245/45/16 in most places.
The bigger ones I have only ever found at Mytyres.

ISTR they don't do a 205/55/15. Put 225/50/15s on -- they're pretty much the same rolling diameter.

Bob, When Porsche test and approve a tyre for the first time it is given an N0 rating. If the manufacturer changes the spec of the tyre and Porsche retest it they then give it an N1, then an N2 and so on.
Porsche did not bring in the N system until the 964 and 968 came along. They never used this sytem on 944's so don't get too hung up about trying to find the latest N rated tyre - it will have been tested on a 996 or Boxster
If you do want an N rated tyre then the closest thing would be to find one tested on 968's but remember they stopped making 968 nearly 10 years ago anyway. Your local OPC should have a list of all the N rated tyres and for which vehicles, so just give them a call.
