By driving correctly and moderately, and maintaining proper tire air pressure:
- Correct answer: The tires’ life span is prolonged.
- The engine’s fuel consumption is increased.
- The vehicle can drive faster.
- The engine’s oil consumption is increased.
Why this is the answer
The correct answer in the official bank: The tires’ life span is prolonged.
Smooth, moderate driving without hard acceleration, sudden braking or fast cornering reduces tire wear. A tire at the correct pressure touches the road evenly and wears slowly and uniformly. Under- or over-inflation causes uneven wear and shortens tire life. These habits therefore prolong the tires' life span; they do not increase fuel or oil consumption.
