Original tires never dismounted from factory rims

[91GT]

Does anyone have any advice on how to store tires still mounted on the original rims? I have a 91 that still has the original tires from the dealership mounted on the pony rims. Took them off and put new tires and replica wheels just to preserve the integrity of the 20 year old tires that only have 25,000 miles on them.

I saw this a while back. It might give you some ideas.
