TSC still sells tire spoons and i have always done the board and driving on deal to break down, another trick to get them to seat is "now this is a safety first deal" to lay them on the ground spray in a fair amount of ether / starting fluid , get a lit match NOT A LIGHTER and throw the match at the bead. the small explosion that ensues is enough to seat the bead in most of the time and if you are out in the middle of no mans land on a 4 wheeler puts enough pressure in the tire to get you home.
so if you are trying to mount narrow tires on wider rims this trick helps most of the time
