I checked the door sticker says 33 front 31 rear but they are for 16" tyres
not my 17"!. I live in the uk and my car is a import jap spec sti.. .

You may need to experiment but as a very general rule, the wider and
probably the greater circumference the new tire is versus the stock tire
the LESS pressure would be required. I doubt it would be more than 2-3
psi less though. If you race, monitor the handling, if not, monitor the
wear - too low pressure, wear on the outside - too high, wears the
center (assuming proper toe and other alignment).

Why not check at your local tire reseller as I am sure that he
will have publications with the correct pressure for your size
vehicle.

14, 15, 16, 17 inch, the pressures should be about the same.

While different tire models (even the same size) may require
different pressures to match the preferred ride/handling
trade-offs, the starting point should be the recommended
pressures on the sticker. Move upwards from there until
handling becomes better and the ride gets to your
tolerance for harshness. This is a very rough guide.
There is no absolute 'right' pressure for any car/driver combination.

The pressures are calculated to provide the right size
tire patch area which is relatively constant for each
model of tire. Only the shape of the patch area may change.
