There is a negligible difference (2.5mm) in sidewall height but as you have changed to alloys take an experience of 2 psi less.

Refer to what the manual says and also ask your Maruti ASS as to what the recommended tyre pressure is. 185 is used by the ZXI but thats a lighter petrol engine in the front. For the diesel engine it's better to keep a 2 psi increase atleast to offset the increased engine weight and also to aid lesser steering effort.

i thinl MUL recommends 29 psi for ZXi, so a 30 or 31 should be fine for a VDi with 185's
