Because saber toothed cats became extinct before written records, much of the behavior of saber toothed cats can only be speculated on.
There is a possibility that some species of saber toothed cats lived in groups, like modern lions. Some evidence for this is that there are bones of saber toothed cats who were crippled, but had enough time to partially heal before they died. This only seems possible if they were cared for by other members of the group.
Judging by their body structure, they hunted by ambushing prey such as bison or mammoth to a close distance (they weren't fast runners), and then they would tackle it with their very strong and muscular forelimbs. They would kill their prey by opening their mouth 90 degrees and then using their strong neck to stab the animal in the throat (they had a weaker bite force then modern big cats).
Probably quite similar than that of the big cats of today. Probably more like lions than tigers, since sabertooth cats (Smilodon for example, but there was many species) lived in plain areas, like lions of the savannah, while tigers live in forests.
