Store wheels inflated or deflated?

After a sizeable wheel/tire investment, I`d like to know which state would be the best to keep them in.
I`m surprised at the amount of air they are still holding after more than a couple of months.
Sorry for the newb question.
TIA

either or, but if deflated, you don't want the weight of the bike to cause the tires to sag, as this leads to premature sidewall cracking.

It doesn't matter if the bike is hanging, the air will bleed anyway.

But if the bike is stored on the floor, you want to keep some air in the tire, otherwise they'll dry out with the flat spot. This cause some checking of the rubber when you inflate them next spring.

Goatalope is closest, the ideal is 66.66% of riding pressure

And if you use Road Tubeless with sealant, you have to keep them inflated and regularly rotate them, or the sealant will leak out and/or puddle in the tire.

If I were the OP then pretty likely. Since I have kept my bikes from the 80's some still have sewups.

Thanks for the replies. I should have mentioned the tires are new Specialized clinchers mounted on new Ambrosio rims.
I guess I`ll leave them inflated but will suspend the bike off the cold cement floor, it`s my understanding that it`s not an ideal place as it can harm the rubber.

It's not the cold that harms them. It's the pressure on the sidewalls from being left flat and pinched for a long time. Unsealed concrete CAN leach up some of the stuff that is in it. But nothing in the concrete or that may leach out will bother your tires. Suspending the bike is wise in any event since it means that you don't need to think about going out to the shed or garage every couple of months and inflate the tires again.

+1 all my bikes save for my commuter are on tubulars. And I'm building a new pair of wheels for a good friend, tubulars, of course.

No doubt about it, wired-in tired have improved tremendously over the last 2 decades, but tubulars still set the bar to pass.
