I'm surprised no one has responded.
2.3-2.4bar and 70deg C according to this:

The air pressure is going to be different for all cars. Yokohama has not given us any exact pressures. They normally recommend to start with factory pressures and work from there. The ambient temps and type of track would have a lot to do with starting pressures.

On the track, I run mine at 40psi front and 24psi rear. However, mine are medium compound and the weather is usually >80F.

I realise that.

but the optimum carcass temp wouldn't be different between cars as long as the compound is constant, and no one's seen that info either.
