What's the current recommended PSI for 21" wheels on P85D?

Upgraded from 19" cyclones to 21" turbines. ContiSportContact 245 square setup. The user manual no longer states recommended pressures. What's the current recommendation? 42 PSI?

Mine says 42 psi in the door sill- assuming it is the same as a P85.

Are you guys running Nitrogen or O2 in your MS tires?

I prefer to fill my tires with a very special mix of approx 78% Nitrogen, approx 21% Oxygen, and a small bit of other 'stuff'.
