Question:
I've been told that when the tires of an automobile hit something, let's say a small animal, the animal would be thrown forward, in the direction that the car is heading. However, with the gripping treads on the tires, shouldn't the thing be pulled under the tire, and crushed by the immense weight of the vehicle? Thanks in advance.


Replies:
It depends upon which part of the tire hits first. Overall, the tire is moving forward, so in general a collision with something will impart a forward momentum to whatever gets hit. However, the bottom of a tire really isn't moving at all. The "gripping treads" of a tire won't pull anything under a tire, because they're not moving backward. Instead, the lower forward quarter of a tire is mostly moving downward; it will push down on anything under it as the car moves forward. That's why small items are crushed instead of thrown clear.
