If you really want the tires off of the ground I would recommend removing all four or the "Y" stabilizers and replacing them with eight scissor jacks appropriately placed so as to support the entire trailer. Instead of eight jacks you could use cement blocks but that is assuming you do not intend on moving the trailer maybe once a year.
