It may improve handling

It increases tire longevity
It has no significant impact on driving

The correct answer is: It can cause decreased fuel efficiency, tire blowouts, and poor handling

When your vehicle's tires are under-inflated, it can lead to several negative consequences, which is why this option is the correct answer. Under-inflated tires create a larger contact patch with the road, which can increase rolling resistance. This means that your engine has to work harder to move the vehicle, ultimately leading to decreased fuel efficiency. Additionally, lower tire pressure can generate excess heat due to increased friction, making blowouts more likely as the tires are unable to adequately support the weight of the vehicle. This also affects handling—under-inflated tires can lead to a loss of control, especially while turning or during sudden maneuvers, as the tires do not respond effectively to steering inputs. Overall, maintaining proper tire inflation is crucial for optimal vehicle performance, safety, and efficiency.
