Hi Barry,
I recommend 32 PSI all round for normal use. If you want to save some money on fuel, go up to 37 psi all round, it will sacrifice a little grip though.
More importantly, the pressures should be fairly even, side to side. Without power steering a low tyre on one side can feel like a tracking fault, making the car pull towards the low pressure tyre.
Most of the published tyre pressure data is for the original crossply tyres, these were operated at a much lower pressure because the carcass is a lot less rigid.
I hope this answers your question.
Paddy
