997 tyres

[culminator]

Am I right in saying that the N rated Michelin PS4S are not available for 19 wheels that are on the 997?

If so, would be recommend the non n rated Michelins or Continental Sport Contact 7s. I can get both locally and the price difference is negligible.

It’s a weekend car only

Either of those options are great. I have had non N rated without issue and were far superior to the N rated P Zeros the car came on from factory.

P Zeros are a terrible tyre. Even worse in wet conditions. I keep telling myself that I’ll swap to the Continentals, but I always end up with the PS4S’s.

Saw a Spyder RS recently on Dunlops, owner said they were excellent. Maybe worth a shot. I always use them on the wife’s Jags.

SC7s great tyre, but firmer ride and wear rate is higher than PS4S.
I would go normal PS4S and forget the N rating.

I think the non N rated tyres ruin the steering and turn in.

I ditched mine after a few weeks and went with the new Bridgetsone Potenza Sports, but would have gone CSC7 if they had been available.

But much prefer the Bridgestones to the Michelin, which are too soft.

On my E Class daily I have ditched the PS4S because they are too bloody firm! Amazing how much difference the "same" tyre can be when specced for different manufacturers.


Let's be realistic here though, there all good, and all have compromises. For me a bit more wear is worth it for keeping that great 911 steering, while others will prefer the extra wear and softer ride, on the Merc I lost the sharp steering that the Michelins had to get rid of the crashy ride.

I have done over 10k miles in 3 years on CSC7's and they are stiff (rears at the crazy recommended pressures are too hard) but I still have >3mm rear tread and >5mm front. I run wide wheels and 235/305 and 30/34 tyre pressures. A very good tyre dry and wet

[Ed.Neumann]

Good point on tyre pressures, no idea why Porsche only put the pressures for full load and going over 230kmph on the 997 on the sticker for some markets.

The recommended comfort option is 32f and 34r but is never listed.
