Tire without a tube can be plugged or you can use fix-a-flat. If a tub is punctured; it is done. That being said, tubes can be used for old tires that have tread that will not hold air or have dry rot, but they do not replace a good tubeless tire. For a split tire, just order the large o-ring for the rim, I have used caulking, cut big chunks of rubber, but nothing will work as good as the original.
