Folks, I know of NF0 tyres its what I select for my 20" Tacan tyres.. In fact Until recently it was the only code approved for Taycan that I was aware of.

But for a while, I have seen references to NF1 and NF2 - but searches for NF1/2 for my tyre size R20, just show the same limited choice of tyres as a search for NF0 - and they are all coded NF0

What's the difference between these codes please? I suspect it's purely diameter 0=20, 1=21, 2=22? ....

Cheers

The numbers 0, 1, 2 have no co-relation to tyre/rim sizes. The numbers signify revisions of the tyre compound.

---

Porsche uses a two‑letter system to show which Porsche model the tyre is designed for.

NF = Porsche Taycan
Other examples for context:
  • NA → 911
  • NB → 718 Boxster / Cayman
  • NC → Cayenne
  • ND → Panamera
  • NE → Macan
  • NFTaycan
The number after NF is the revision (generation) of Porsche approval, not tyre size, wheel diameter, or performance grade.

NF0 – First Porsche‑approved specification for that tyre
NF1 – Updated revision (compound, structure, or construction tweaks)
NF2 – Further evolution of the same tyre model

- A higher number does NOT automatically mean “better”.
- It simply means newer homologation following Porsche and manufacturer updates.
- NF0, NF1 and NF2 can feel slightly different due to changes in:

Sidewall stiffness
Load handling
Noise reduction
Rolling resistance

Thank you PG for that comprehensive Info! Very much appreciated - I had no idea!

So, does that mean that IF a dealer offers NF0 only (and the websites of most big suppliers in the UK do that) does it mean it's old stock?

I can't find NF1/2 specified yet, but have not done a deep dive yet....

or simply that they can't be *rsed to update their web-site to give the actual spec - and it will say NF1/2 on the tyre even if the online spec says NF0?

cheers

No it does not mean it's "old stock".
It's just an older tyre model that was homologated a longer time ago, but that doesn't mean the tyre was made a long time ago. Michelin is making PS4 to this day, so they can be a few months old, even if they are NF0.

NF1 is not any better than NF0.

As written by @prj 🙏🏽 above... it doesn't matter.. NFO is as good and not older.

I had NF1 and NF0 on several cars, the goodyear NF1 are more prone to bubbles for some reason, the Pirelli NF1 are very noisy, at least with PAR... not sure how they are as NF0.

If you're ever worried about being given old stock, ask for the date marker on the tyres.

They have a 4 digit code. First two are the week in the year of manufacture, second two the year.

You'll be able to see these on your current tyres if interested 🙂

Thanks M that's good to know - I'm not so much worried about dates as such -

It was just that, given the info (from here) that NF1/2 are more recently approved tyre compound specs - and hence probably marginal improvements (so I thought otherwise why bother?).

This made me curious as to why I can only find NF0 in UK main suppliers and not NF1/2. I guess there is hysteresis in the manufacture/supply chain..

Anyways it was only curiosity... good to have decent info. Thanks.

This porsche dealer says

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.

I had a tyre replaced after a pothole engagement a few months back. Eagle F1, Porsche approved tyre etc.. I did not pay much attention to the NF rating. My car is in at the Porsche dealer now and they called to say that the NF rating should be consistent, i.e. all NF0 or all NF1,2 etc, particularly on the same axel. Will have a longer chat when I go pick it up.

Yes, that is quite a normal requirement on all cars (regardless of manufacturer).

A car should ideally have the same 4 tyres all around, but definitely not have different tyres on the same axle...

Thanks, I was not suggesting it is normal to have different tyres. Just saying you need to pay attention to the NF number as well (which is specific to Porsche) more than what I did, as it is not normal (at least for me and for others who have posted) to look out for such things. I checked it was Goodyear Eagle F1 305/30 R21 Y
e.g. BMWs had a star, that was it, it was BMW approved, no lettering or numbers, revision versions etc.
In addition I would have expected a replacement of the same tyre when you ask for a replacement tyre as I am evidently not a tyre expert.

If we all had the courage of our conviction, we would use any tire that matched size. Electric cars are variable wheel speed as needed, regardless of the traction of the tire, the car will adjust (generally). The only consideration is getting the best traction tires, matching or not, for your price preference. "N" stands for nonsense. If you are cost conscious, then go for whatever matches size with a high treadwear designation (>500)- all season lower traction tires. You can buy inexpensive Chinese, Vietnamese and Indonesian tires, if you wish. Go to ebay and look at matching (unpatched) take-offs. Caveat being to read the age code and avoid >4 year old tires.
