If it's the same as the Mk2 GT3, then they are:
235/40 ZR 18 (91Y) PS2 N2 (front)
295/30 ZR 18 (98Y) PS2 N2 (rear)

...although I'm guessing yours a wider?

The sizes are correct. The car came from the factory on Pirelli Corsa System N6's, which are much better than the PS2's.

If you plan to track (why buy it otherwisesmile) the car Michelin Sport Cups are the tyre of choice. Toyo R888's are a lower cost alternative.

tnk u , yes the current tyres are PS2's which are fine, but i fancy something a big more focused so will go for the PCSN6's

Are the Corsa System tyres decent in the wet or are they like Michelin Pilot Sport Cups in being a bit tricky?

I have Cups on a second set of wheels for proper track days but on wet days I found the Michelin Pilot Sports to be very good and obviously also a decent road tyre - if the Pirellis would be better as an all round road/wet track tyre I'll give them a go.

The Corsa System is an excellent wet tyre. Comes with 7mm of tread from new (and at 295 width on the rear) so obviously not great in deep standing water - overall fantastic in the wet though, on road and track.

Big Thread Resurrection.

But whats latest thinking on tyre choices for 996.2 GT3/RS? Still either PS2 or some form of Pirelli P-Zero, for best road biased options??

Have seen Cup2's in suitable sizes, but not -N-Rated.

I use Cup 2s in std 996.2 sizes for road and track. N rating is irrelevant with these cars unless under warranty (are any 996s still under warranty?)
Interested to hear experiences of other brands of track spec tyres.

I also would interested to hear if people have experimented with some slightly different sizes - eg wider tyres than std.

I’d stick with the original sizes. In terms of tyres, the cup 2 is a very good all round tyre and will give you reasonable stint times before it goes off - but not as good as the earlier versions which were excellent in that respect. From personal experience the Pirelli is also a good tyre. I found that other tyres have a tendency to go off very quickly. For example, I can never get more than 4 laps out of the Toyo 888’s before it has gone off.

I generally run Cups at 2.1 bar hot on track. If it’s very wet I’ll increase the pressures to open the tread. Cups are fine in the wet if you are reasonably experienced, just be careful To keep the nose slightly loaded in standing water.

As a tip, on a clock wise circuit, my starting pressures will be 1.8bar on the passenger side and 1.85bar in the drivers. If you are a reasonably peddler In good conditions, Within 2 laps they will be pretty much spot on and you won’t need to bleed them.
