Actually, the stock tiedowns are just OK for light items, and are not particularly conveniently placed. If you tie down a tire though, be advised your tire may demonstrate aerodynamic qualities in a crash if you just use the stock tie downs. If you are still around to care, you will have new drain holes in the floor where the tie downs used to be.
Far better would be to weld a captive nut to some fairly size-ish 3/16" plate or thick large washers, then attach same to the floor via welding or epoxy to just hold it conveniently in place. Then put 'em wherever you want.
Will tack weld for pizza. You purchase, cut, drill and fasten.
