When the tire air pressure is too low, it might cause:
- Quick wear and tear of the braking system.
- Easy wheel manipulation.
- Correct answer: Tire overheating.
- Low fuel consumption.
Why this is the answer
The correct answer in the official bank: Tire overheating.
When tire pressure is too low, the tire's sidewalls flex more with every turn of the wheel and more of the tire touches the road. This constant flexing and friction build up a lot of heat, which can cause fast wear and even a blowout. Low pressure also makes steering heavier and raises fuel consumption rather than lowering it. Check tire pressure regularly, when the tires are cold.
