  The upper bound of the fine-grained uncertainty relation is different for
classical physics, quantum physics and no-signaling theories with maximal
nonlocality (supper quantum correlation), as was shown in the case of bipartite
systems [J. Oppenheim and S. Wehner, Science 330, 1072 (2010)]. Here, we extend
the fine-grained uncertainty relation to the case of tripartite systems. We
show that the fine-grained uncertainty relation determines the nonlocality of
tripartite systems as manifested by the Svetlichny inequality, discriminating
between classical physics, quantum physics and super quantum correlations.
