What is one of the major impacts of low tire pressure on a vehicle?

1. Improved handling and control

2. Increased fuel efficiency

3. Reduced tire wear and pressure

4. Compromised vehicle handling

The correct answer is: Compromised vehicle handling

Low tire pressure significantly compromises vehicle handling because it affects the contact patch between the tires and the road. When the tires are underinflated, they cannot maintain optimal shape, leading to reduced stability and responsiveness when steering. This can result in longer stopping distances and decreased overall vehicle control during maneuvers, especially in emergency situations. The vehicle may also experience increased rolling resistance, which can further influence handling characteristics negatively. In summary, maintaining proper tire pressure is crucial to ensure that the vehicle adheres to the road effectively, allowing for safe and reliable driving dynamics.
