Managed to get a screw in my tyre :( not much tread left so will have to replace it and the other side for balance which I dont mind, but... I have mitchelin pilot sports on the front with a fair bit of tread, these are N1 rated, if I put the same on the back £205 each :eek: things are ok, but if I put pirelli p rossos £165 which are N4 rated Im breaking manufacturers spec which could cause insurance problems. I am told by my dealer that n1 on the front and N4 on the back will make the car unstable (not sure i believe it). So I have to spend £40 more a tyre, and when the fonts go still have to spen £40 more each again or get a full set of pirellis now which are a higher N4 spec tyre. 2x Michelin £410 or a full set of pirelli I can get for £596 after much deal talk. I just feel Im getting screwed by red tape with the N rating, but is it worth insurance issues? Or worse handling issues when Im on a performance driving course next weekend. i know theres a few petrol heads on here, what do ya think?
