Well, letâs talk size first. Tigers are heavier, weighing up to 800 pounds to the lionâs 550. But the two cats arenât so different in size. You might remember from high school health class that muscle weighs more than fat, which helps explain the tigerâs extra pounds. So it seems that the tiger would have a physical advantage over the lion.
This will make the tiger canines to be atleast 4 times bigger and heavier than the lions. Here is the picture of a 6 inchish tiger canine compared to 4 inchish tiger canine (credits to grizzlyclaws). The first one on the left (6 inchish), and the second one on the right (4 inchish).
