Depends on the car and spare. On my car the spare is a much more thin tire compared to my regular ones. It’s meant to act as a short-term fix to get a proper tire back on. This type of spare isn’t meant to be used long-term.
Since it’s a different form than a typical tire, many spares (mine included) are almost double the PSI (~60) than my typical tire.
I’d say just make sure you check on the tire itself! It’s definitely likely it’s different from the main tires for many makes and models.
