What is a consequence of driving with underinflated tires?

Driving with underinflated tires leads to reduced steering control because insufficient air pressure in tires can cause them to flex more than intended, which affects the responsiveness and handling of the vehicle. Underinflated tires deform under load and can lead to poor contact with the road surface, impacting steering precision and stability. This can especially be dangerous for commercial vehicles that require reliable steering and handling due to their size and weight.

In contrast, improved traction in wet conditions, increased fuel efficiency, and extended tire life are not associated with underinflated tires. In fact, underinflation tends to reduce fuel efficiency due to increased rolling resistance, can lead to shortened tire life due to uneven wear, and generally results in poorer traction rather than improved traction in any condition. Understanding the importance of maintaining proper tire inflation is crucial for both safety and performance in driving commercial vehicles.
