Not sure for the GS, but on the IS, Tony@WIM recommends 35psi all round, although some are now using 38 with that tyre size and are very happy with the results.

Probably worth experimenting with both and see which you prefer.

My handbook for GS430 says 245/40/18 on GS are recommended 32 all round. This was written in by previous owner after he contacted Lexus to ascertain correct pressures.
