Suggestion
Going to go one step further with the next set (rears) and go for a non OEM size too (275/35/18 instead of 285/30/18) so I can put PS4s on the back too.

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.

Evening all,
Why won't anyone sell me tyres!!
Was out in today's beautiful weather and decided to replace my ageing Pirelli zero Rosos with 2 new front of Michelin's PS4s as had heard good reviews..
Basically my tyre centre would not sell me them as they're not n rated?
Does it really matter folks?
Kind regards
Mark
No it doesn't matter. Porsche have a limited range of N rated tyres for older cars, I can't imagine that they will continue testing and approving new tyres for older cars.............
I asked that self same question of local tyre fitter and he had no issues. Got PS4 fitted to my wife's car (Hyundai veloster turbo) and they are amazing!!
PS4 a better tyre in all regards. Any tyre fitter who won't put them on is a jobsworth who doesnt understand anything beyond his tick boxes. I ordered my PS4s from Blackcircles, got them fitted at an ATS - the guy there just asked to make sure I knew which tyres I'd ordered, and that I was ok they weren't OEM, and I said of course.
Going to go one step further with the next set (rears) and go for a non OEM size too (275/35/18 instead of 285/30/18) so I can put PS4s on the back too.

No idea why Magic919 doesn't think they suit the car as the PS4 is a replacement for the previous version of the PSS and Chris Franklin at CG was happy with my choice too...
Appreciate both your help.
I've been running sport contact 2's on the rear with front zero rossos for 2 + years now and not had any problems.
It will be interesting to see how the ps4's grip in both the dry and wet. I do find the rosso's poor in the wet. And like the sound of ps4's all round!
I'll give you some feedback once they're on

N Rating is a recommendation, unfortunately N rating tyre homologation comes after new tyres a launched globally and as have seen the latest tyres can be out of step from being N rated.
the Pilot Sport 4S are the best non N Rated tyres out there and are an excellent choice
