A hydrodynamical model is developed for general-relativistic strongly magnetic collisionless plasma to shed light on general processes taking place in MHD flows with anisotropic pressure tensors. The model is a generalization of the model by Lominadze et al. (1990) presented according to the '3+1' formalism by Thorne and Macdonald (1982) and the orthonormal tetrad technique. The equations of state are obtained for the ultrarelativistic limit, and they represent a significant deviation from previous transport equations. The present expressions are theorized to represent the processes that occur in relativistic MHD flows with anisotropic pressure tensors such as various kinds of astrophysical flows. These flows are expected to be found in such phenomena as relativistic pulsar winds in which radiation and pair-production processes are not significant.
