What is the consequence of driving with under-inflated tires?

• A. Improve fuel economy
• B. Cause overheating and blowouts
• C. Decrease tire wear
• D. Contribute to better handling

Answer: (B)

Driving with under-inflated tires significantly increases the risk of overheating and blowouts. When tires are not adequately inflated, they are more prone to flex and deform as they roll, which generates excessive heat. This heat can lead to tire failure, resulting in a blowout that can compromise vehicle control and safety.

Proper tire inflation is crucial for ensuring that tires maintain their shape and performance characteristics. Under-inflated tires create greater rolling resistance, which not only affects fuel efficiency but also exacerbates wear on the tire structure. The increased friction and heat generation diminish the tire's lifespan and overall safety while driving.

Conversely, the other options do not accurately reflect the effects of under-inflation. For example, under-inflated tires do not improve fuel economy, decrease wear, or contribute to better handling; in fact, they negatively impact vehicle performance in these areas. This highlights the importance of maintaining proper tire pressure for both safety and vehicle efficiency.
