if a month or two I do nothing.
You may want to add some stans, keep it aired up and shake it from time to time
My alternate wheels always have very different tires so I don't need to swap tires so they do get rotated from time to time
I would buy an Aeronautical air tight box with 36 cubic inches of extra space and store at 14 Celsius degrees in an unlight space 140 meters from the back of house on the left side if facing north. I Would highly recommend running a continuous dehumidifier to be safe.
