I use about 10 rolls of duck tape and wind it around the tires, pack them in black trash bags, about 4 times, push them under the bed.
When spring time comes I take the tires out of the trash bag, leave the duck tape on unit the fist race. Before leaving to the first event I take off the duck tape and the tires will sick like hell.
If you don't have duck tape and have no space under your bed, the bags will work also
Good luck and cheers.
