The **tires** are an essential part of the vehicle, as they are the only point of contact with the road. However, their ability to absorb road irregularities is limited. According to the information provided, the tires can only absorb approximately **10%** of the road irregularities. This means that the rest of the work of impact absorption and maintaining vehicle stability falls on the **suspension system**.


The suspension system is crucial for maintaining constant contact between the tires and the road, thus ensuring vehicle stability and passenger comfort. Without an adequate suspension system, the vehicle would experience more vibrations and be more difficult to control, especially on uneven terrain.

Therefore, although the tires play a role in absorbing small irregularities, their capacity is limited to 10%, and it is the suspension system that takes care of most of this work.
