Tyre Pressures for Donington

[smiffack993]

Can anyone help with a tyre pressure issue ??? Im doing a track day on Friday and there is a good chance of rain. Can anyone suggest some tyre pressures I should start at. An inexperienced guess would be to add a fair ammount more PSI to compensate for the lack of air temperature. Although if its wet, it may better to keep the pressures lower.

Car is a C2 993.

Can anyone correct me if im wrong here or suggest anything else.....

It's quite cold and damp so you will have trouble getting much heat into the tyres. I presume your standard road settings at cold are 36 psi all round. If this is the case then I suggest you do a couple of laps and then bleed of the excess in the rear tyres to get back to 36. Shouldn't have to do much more than this.
