996 Tyre pressure - Nurburgring
Discussion
Hi reading that thread about the GT3 crashes at Spa I'm getting a bit nervous about my upcoming ring trip. When I went to bedford I dropped the tyre a couple of PSI putting them at 34:42 The car was a pig and Don Palmer advised to drop them to 36:36 or even 32:32
I dropped them to about 34:36 when warm and the car was a peach. Bedford is a good place to learn about limits and the tyres can get nice and warm. At the ring I'll be doing one lap at a time and letting the car cool.
What pressures should I be looking for hot and cold? I don't want to find out the hard way.
Cheers.

As a good basis i was always told to run the car on standard pressures,then do a couple of laps(in the case of the Ring-1 lap),you will find that when you get back they will have gone up quite dramatically(say 4-8 psi).Then drop them down to the standard pressures again.
I do this at the Ring,then maybe after 3 or 4 laps do it again,then leave it like that whilst you are there.Make sure you pump them up for the journey home though.

Contisport contacts are deep tread standard road tyres? I think I am right?
If you're planning on driving fast on the 'ring and it's dry (if it's wet you're on the money) the tyres will prove to be quite awful. The deep tread will move around and the tyre will quickly overheat giving the car that jelly like feeling just when you want it to feel taught. Or something like that.
As for pressure reccomendation, you can do it by feel. After each lap adjusting down until you're happy how the car feels. Obviously after lap 1 you could probably let out a relatively large amount, and at the very least reduce to standard pressure as they are sure to have sky rocketed. Then it would be ok to make smaller adjustments front and rear until you are happy with the balance. Going down too far is a pain as you have to put air back in!
Using Michelin cup tyres the 18 inch type for a 996 GT3, I like to run 2.1 front 2.3 rear, but that is my preference and they are quite a different tyre to your conti sports.
There you go, no help whatsoever.....

i ran mich pilot sport (not cups) between 32-34/32-34 at the ring last weekend, conditions were changable but didn't get a lot of dry running except sunday.
tried my first lap at standard pressures 33/39 and they had heated to 37/44 by the end of the lap. felt very unbalanced.
just don't forget to pump them up after they've cooled.
the car was mindblowing at the ring, once i'd got used to what was possible. fantastic place, be careful but above all confident. it doesn't suffer fools gladly, as one of my mates found out in his 996c2 on the approach to hatzenbach.

Can you recommend the Mich pilot sports ? I currently have contis but they are in imminent need of replacment ? tried my first lap at standard pressures 33/39 and they had heated to 37/44 by the end of the lap. felt very unbalanced.

2something,
sorry, i couldn't really say because i haven't run the car long enough to try an alternative tyre. of course a toyo888 or cup tyre would improve grip by a considerable margin on a dry circuit. i'll prob swap to the mich pilot cups when they need changing.
i'm sure the subject has been discussed at length on this forum before.
