A search for "tire storage"
leads to all sorts of worthless stuff, and hardly seems worth the time to me. Earlier I searched specifically for "wood" within the only the Goodyear and Michelin web sites for North America to find anything authoritative - there was nothing, although that's where I found the care guides.
"tire storage Michelin", "tire storage Goodyear", and "tire storage Bridgestone" did lead to a Michelin Tire Storage
page and another Every Day - Storage
page (nothing new), a Goodyear RV tires Tire Storage
page, and a Bridgestone / Firestone manual
with a tiny storage section. The Goodyear page does have some interesting bits:
If tires are being stored outdoors, they should be raised off the storage surface
Don't store tires on black asphalt or other heat-absorbent surfaces
- the asphalt concern is about heat
- there is no concern expressed about concrete
- storage loose and storage on the vehicle are separate scenarios
- there is lots of guidance about inflation pressure
