I can let go of the rims with tires that need to be replaced, not bald yet. Should be good for your purpose. How is $150?
They don't leak or anything so you can actually take car for a spin on try day to keep the fluid moving and batter charged.
Alternatively you could jack your car up on stands. But idk if that would loosen up the suspension...or leave stress marks on jack points..
NVM 16inch rims won't clear your brakes. I highly doubt it. Someone can double check.
