Before a long trip, you see that one of your tires looks low on air. What does the handbook say about driving with low tire pressure?
Correct answer: It lowers fuel mileage, and a car in poor condition can break down and crash.
Why
Low tire pressure makes the car use more fuel. A car that is not kept in good working condition costs more to run and is more likely to break down or crash. Check your car before you drive, and add air before the trip. Gradual slowing and less stop-and-go driving also save fuel and wear on the brakes.
