Felines will win, no mater what. For example, Lions have big paws and long large claws. A lion could smack a wolf on the side of it's head and the wolf could suffer from brain concussion.
Also the lions head is bigger, and the canines are larger and have a deeper root for holding on to prey. The lion is also heavier and taller, bigger the badder.
Sorry, wolf founders. A lion will win in most cases. There has been, actually, some reports of wolf PACKS killing mountain lions or bears. I don't know about tigers though.
