What is the significance of checking the air pressure in tires?

Checking the air pressure in tires is crucial because it helps avoid blowouts and ensures optimal fuel efficiency. Under-inflated tires can generate excessive heat, leading to a higher risk of blowouts while driving. Maintaining the correct air pressure allows tires to perform properly, maximizing the contact area with the road, which contributes to better handling and stability. Furthermore, properly inflated tires reduce rolling resistance, which helps improve fuel efficiency.

While the other options highlight important aspects of tire maintenance, the primary concerns are safety and performance. Compliance with safety regulations, extending the lifespan of tires, and improving traction are all benefits of maintaining proper tire pressure, but avoiding blowouts and enhancing fuel efficiency are more immediate and critical outcomes of having tires at the correct pressure. Without proper inflation, the risks to safety and economy are significantly increased.
