Why N rated tyres for Porsche ?

This is worth a watch ... PS4S for BMW but just an example of how the manufacturers work with Michelin ....

Still not as good as newer, non N rated tyres.

Yep, there are those that insist on buying N rated tyres that havent been updated in decades and then there are those that claim non-N rated invalidates your insurance and MOT

Possibly the case that newer tyres could be better -- if available in the right size -- it would be useful if Porsche could keep us informed but I guess they get a cut out of an N rating and wouldn't use non-N rated tyres on new cars ... ??

I do it through a combination of laziness and use of extended warranties in the GT cars. Out of warranty I make other choices.
