Tyre pressures for airfield day

[ezekial]

I am doing my first airfield day at North Weald next week. Theres a high speed corner and some kind of handling circuit.

I am wondering what kind of tyre pressures I should be running for this?

I have a 2017 440i.

255/35/19 rear and 225/40/19 front. Tyres are Goodyear Eagle F1 Asymmetric 6.

Usually for the road I run 38 psi rear and 35 front.

If anyone has some experience / tips here on what would be optimal it would be helpful. I do have a tyre inflator so can adjust on the day.

Thanks!

If you've not done that kind of thing much before try and keep them at your normal pressures, keep checking them through the day as after a hot lap or 2 they'll rise up but how much really depends on the car, conditions and how you're driving it.

Airfields can absolutely wreck tyres in my experience so budget in for a new set straight afterwards!

Ive had a lap of the nurburgring but never a full day thing like this before.

Thanks for the advice, I'll start with normal pressures and try to not scrub them too much!
