991.2 GT3 tyre pressure help pls

[MARTIN993]

Evening All,
TPM is driving me up the wall.
It’s showing high pressures 32 fronts, 38 rears (which I can believe as just hacked over to Belgium ahead of Spa track day).
When I go to ‘Fill info’, it asks for more air, though.
What am I missing?
On track I’m assuming letting air out as tryes warm is sensible; how this marries up with the track setting in TPM, I cannot get me head around. The book isn’t helping much - just confuses me further.
Perhaps this warm weather and tarmac bashing is making me slow, somehow!
Any help welcome

I’ve always found the car’s view on when to add/remove air is useless.

Just stick to the door sticker for road driving and get some advice from here for recommended hot pressures when on track.

Its yust what you think most important.
If you want best grip for the race, lower the pressure, but then your tires can be trown away after the race, or you get accident on the way home by blowing tire. Even if yiu highen up the pressure after the race. The beginning damage is done, and builds up in time.

If you want to safe your tires, dont lower the pressure warm. The tires need the lesser deflection this gives, to give lesser heatproduction, because cooling down of the rubber is also less, because of the smaller temp-differences between rubber and inside air.
Read recently that F1 racing tires last only 60 to 120 km , and you dont want that for your tires.

Bought an electric tyre pressure monitor and had fun experimenting with pressures. Let about 6 psi total out throughout the day. Thanks all!

6spi sounds about right. Hopefully you enjoyed the day and pumped them back up before driving home!

Yes sir!
