These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

3 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

POST 1 / ORIGINAL POSTEROriginal post

Hi guys I need advice on tyres my 996 c2 cab has got pirelli all round now the front need changing 225/40/18 n4. I was shopping around and found dunlops for £150 pair new but not sure if n rated. Does it matter about the "N". Got no idea what the N4 etc means. Any help? Thank you.

POST 2Original post

N rating indicates that the tyre has been approved by Porsche, the number is just the sequence order of approval, e.g. first tyre approved for a particular model is N0 the next is N1 etc. I wouldn't recommend fitting a non-N rated tyre.

POST 3Original post

N rating means the tyres have been tested and approved by Porsche. As each manufacturer develops a particular series of tyres, so the N rating goes up by one (starting at N0), Therefore N4 means it is the 4th design revision of that tyre. It is a contentious issue, but it isn't recommended to mix tyres of different brands or N ratings. There is plenty of info if you do a search, and there is some info in the members section (which you won't be able to access). Drop me an email to richard996 at gmail d0t c0m and I'll attach it to a reply.
