Long Term Storage

I'm finished using my CT for the year.
I just use it for transporting racing karts in the summer.
I would like opinions as to what you all do about the tires.
I put new tires on this summer and I'm wondering if I should get the tires totally off the stones in my parking area, put boards under them, or just take some of the trailer weight off of them?
Thanks all,
