Yes, for VF and MY16 VF2 the SS and SV6 got the same 18" wheels as each other (for MY17 Holden deleted the SS-V, and MY17 SS got the MY16 SS-V 19" wheels).
Calais non-V also got 18's, some of them look a bit suss to my eye though (whereas the SS/SV6 wheels aren't as ... fussy).
That silver wagon confuses me a little, because I thought it would be an MY17 SV6 based on the wheels. They may have been used on other special editions maybe, but I'm about 90% sure that the wheels in that pattern with the machined face & black highlights are MY17 SV6, and the same wheels in a silver-all-over un-machined finish are MY16 SV6/SS. So maybe the police DID get special SS's in MY17, with 18" SV6 wheels instead of the 19" MY17 SS ones.
The sedan is wearing VF1 SS/SV6 wheels.
