What is one critical reason for checking tire pressure before a trip?

Checking tire pressure before a trip is crucial for ensuring optimal vehicle performance and safety. Proper tire pressure is essential for maintaining good traction, fuel efficiency, and overall handling of the vehicle. Under-inflated tires can lead to increased rolling resistance, which not only decreases fuel efficiency but also affects braking distance and increases the risk of tire blowouts. Conversely, over-inflated tires can lead to a harsher ride and uneven tread wear. By maintaining the correct tire pressure, drivers can enhance vehicle stability and reduce the likelihood of accidents, making it a fundamental aspect of vehicle preparation for any journey.
