Someone like @BognorMotors might have a definitive answer, otherwise it's trial and error as they are not a standard fitment.
Most of us are different depending on sizes, weight carried and tyres, but I'd start around 42psi and see how it feels.
If that feels fine, just keep an eye of the wear pattern. I smashed through a set of rear Eagle F1s in 4000 miles because I was running too high pressures, and although I'm about there, I'm still wearing out rears much faster than fronts.

Yes, 40 is good.
