Thank you for your response. I do not know the technicalities of suspensions but I think the size I am upgrading to is a Volvo approved wheel size
and I do not think an OEM approved wheel size would need addition of a spacer. Kindly correct me if I am wrong. Thank you.

Never ever use spacers on air suspension as you will throw off the system completely! The system will adjust downwards automatically.

I'm not advocating the use of spacers here. Since the question was on GC and that the suspension was designed to maintained the GC. The GC change - due to change in tyre and due to a change in suspension geometry/BIW are both different, and the car would react differently for both. See my comment below. Which implies you are safe to change the tyre to a bigger size one.
