are NF tyres really required to protect warranty?

[Murph7355]

Why wouldn’t you run nF0/nf1 tyres? Is it price ?

not sure id want to run anything that wasn’t to spec given the torque and weight .

Nope. Better performance elsewhere. In part because Porsche/tyre manufacturers are so slow to release new alternatives.

I run Hankook Ion Evos...same as on the J1.2 only a little wider.

Ref warranty, there's no specific exclusion for non-NF rated tyres that I can see. There's an exclusion for "non-genuine Porsche parts" (Porsche don't make tyres ) and for "The Vehicle has been modified in a manner not formally approved by the manufacturer in writing, irrespective of whether the modification took place before or during the Period of Cover ".

That last one might exclude non-NF tyres I guess. Depending on what the issue was.

There are NF0 ProContacts, but no ExtremeContacts - I know which ones I prefer to run...

The tires with the best longevity / performance tradeoff are Michelin PS4S - not N rated.

TBH though I've gone back to P-Zeros for noise reasons, myself.

Signed off on the three-year PAW this February. Car was on non-NF winter tyres. No problems; in fact they were happy to take my money.

Not possible here, Porsche requires photos the wheels and if it's not NF, then no go.
Keep in mind the underwriters are different in every region.
