The **tires** are the part of the vehicle that most withstands the bumps and unevenness of the terrain. This is because they are part of the **suspension system**, whose main function is to maintain contact between the tires and the road at all times. This system helps the vehicle not lose stability and allows passengers to travel more comfortably, even when passing over small obstacles on the road.


When the suspension system fails, bumps are more noticeable, indicating that the tires are crucial for absorbing these irregularities of the terrain. Additionally, a suspension system in poor condition can lead to faster tire wear, reinforcing their role in impact absorption.

On the other hand, the **chassis** is the internal structure of the vehicle that supports all the parts, but its main function is to protect passengers in case of an accident, not to absorb bumps. The **rims**, on the other hand, are part of the wheel balancing system, which ensures that the wheels rotate correctly, but they are not specifically designed to absorb terrain impacts.
