Best way to store unmounted tires

I recently purchased some Falken Azenis 615K+ tires because Tire Rack was having a fairly smokin' deal on them. I don't really need to mount them on the car for probably another 6-8 months, so will be storing them. I have never purchased tires that were not mounted on wheels immediately, so was curious about the best way to store unmounted tires. Should I put them in a closet inside the house, to protect them from the triple digit temps that will occur in the garage? Are they going go be okay stacked one on top of the other? Perhaps these are fairly silly questions for those in the know, but I don't want to mess them up while storing them.

Stacked on their sides in climate control is best. Those are sticky tires, so I would do what I can to optimize their condition.

They should be okay stacked on each other, although you may want to stick cardboard under and between the tires so the sidewalls don't get imprinted.

You don't want to stack floppy tires on side because it shoves the beads together and will be a nightmare to mount. UHP tires, generally not an issue.

This, plus wrap each one in plastic.

Laced Tires

If it's only going to be 6-8 months and they're streetable tires, then they're probably fine just in the garage. It's not like they won't be seeing triple-digit temps out there when they're mounted on a car that's parked in the garage, after all.

I think it's more of a concern for Hoosiers or some other race tire with an ideal useful lifetime measured in months rather than years.

I can't imagine putting them in plastic bags would make much difference if I put them in the guest bedroom closet. If they never get above 80*, they are not going to off gas much.
