Trailer Storage

[Wolfeboro Matt]

What is the best method of "storing" a trailer for long periods of time? Specifically, I'm wondering about the tires. Should I raise the trailer up on cinder blocks or something so as to get the pressure off the tires? Or should I go out and rotate/spin the tires on a regular basis?

I've taken to winterizing and storing the boat at the marina, so its likely that the trailer will sit for months and months at a time.

Thanks!
