Since the males are better suited for fighting we will be comparing the males
Body Length (mm): lion 2200 - 3000 (2.2 - 3 meters) tiger 2000 - 3300 (2 - 3.3 meters)
Weight: lions 330-430 pounds tigers 488 pounds
So the tiger is bigger which gives him an advantage
Speed: lion 50 miles per hour tiger 37 miles per hour
Although the lion has an advantage here it's still pretty close so it won't give the lion a huge advantage.
Bite force: tiger: 1,000 pounds lion: 945 pounds
Not a significant advantage for the tiger.
