Question 4672
A vehicle is traveling with low air pressure in its tires. How much fuel will it consume?
- The same as if it were traveling with the recommended pressure.
- More than if it were traveling with the recommended pressure.
- Less than if it were traveling with the recommended pressure.
Show answer and explanation
Correct answer: More than if it were traveling with the recommended pressure.
More. With low pressure, the tire deforms more as it rolls and creates more resistance, so the engine uses more fuel to move the car. In the image, the blue passenger car’s front tire is almost flat.
