I don't do it on my trailer but I have friends who don't use their trailer often and when parking make sure the tires are off the ground and sitting on a 2x6 to keep them off the ground and then place a side cover on them........ I probably should myself but use my trailer regularly. (or I use to, gave it my nephew)

I'd rather walk and carry a Chevy hub cap than ride in a Ferd.
I can explain it to you, but I can't understand it for you smile
