Check it regularly and you may appreciate it when you have to use it. I've got a compact spare tire which has a smaller volume than usual and higher pressure than usual meaning it will deflate much faster than regular tire.
It's supposed to be inflated to 60 psi. When I checked it last night, it was down to 30psi.
