80 to 90 front, 100 to 110psi rear. i have run these pressures on my 215/75/17.5 and 9.5 17.5 tyres.

15W40 diesel engine oil will cover you from -10Centigrade upwards.
Correct tyre pressure depends on which size and type of tyre you have and on the axle load - i.e. the heavier the axle load, the higher the required tyre pressure.
