Mixing N numbers on tyres

[mikeg996]

Sorry, I'm sure this has been asked before but I can't get the search function to work. Is it OK to mix N3 Pirellis on the rear with N4 Pirelli Rossos on the front?

Strictly speaking you shouldn't mix N ratings on the car, but for reasons of availability or supercession that would mean you'd have to purchase four tyres when you may only need 1 or 2.....

Try and obtain the correct N rating from another dealer if yours doesn't stock or cannot get hold of the right tyre.

If you are going to mix them - against Porsches' judgement - only ever mix front to rear never side to side

Thanks. I can have either, just that the Rosso N4s apparently wear a bit better. I'm not doing the rears so I'll get N3s on the front to match.
