The only other N rated tyres for the 987 are Conti Sportcontact 2s
I'd stick with the Michelins - 14k including a track day is pretty good, and consistent with lifetimes on the previous 986

All tyres approved for Porsche have to be specially 'N' rated. So, for example, you can get the new thread pattern Michellin Pilot Sports 2 in the size and will perfectly fit the old 986 Boxsters but since they have not been N rated by Porsche for our cars we cannot use them (well, we can, but it would void our warranties and if we were to sell, then someone who knows Porsches well will not pay for those wheels)...
The w,y,z, etc you mentioned are the tyre speed rating which is more relevant to all the other cars and is being phased out...
The Porsche N rating started as historically Z only covered/recommended speed of some 130mph(?) max; so Porsche started to work with the tyre manufacturers to improve those tyres to cover all the speeds Porsche cars are capable of achieving and hence the start of the N rating... Price-wise they are pretty much the same as their non-N rated equivalents, most of the time I have found them a couple of quid cheaper.

"N" ratings, and much more about tyres, are all covered in the FAQ which is pinned to the top of the Boxster section of the Forum [

Not so - you just need to be aware that the tyres will have different characteristics. Under normal road use there should be no noticeable difference. I've run different makes and different 'N' ratings several times with no degradation in roadholding, even on a trackday.
It is not advisable to mix tyres on the same 'logical' axle.

I'm not sure that tyres have any bearing on a Porsche warranty. As my warranty ran out 3 and a half years ago I'm not up to date with the do's and don't's.
I don't really see how they could argue that fitting a specific tyre can break your car, apart from the obvious one of crashing! There was an article in Christophoros that described the process of the testing of tyres for N rating accreditation. The guy in charge of the process was quoted as saying that if we got the drivers to go around the track two seconds a lap slower they would not be able to detect any difference between individual manufuacturer's tyres. It always springs to mind whenever a thread appears regarding this make of tyre is better than that make of tyre.

Isn't the threads more related to Michelins give better mileage than Pirellis but are are really noisy (especially on the 996s) rather than performance? I spent half an hour with the Michelin guy (see pict 19 on page 33 in October PP, hehe [
]) who told me how much effort they had put in reducing the noise issue (it is mainly done by syncing the inside and outside threads to cancel the noise out) on the new Pilot Sports 2 (not yet N rated for older cars) but if you read the 997 forums the noise is still an issue...
