Why is tire pressure checked during a vehicle inspection?

Checking tire pressure during a vehicle inspection is essential for several reasons, primarily related to safety and fuel efficiency. Properly inflated tires ensure optimal contact with the road, which enhances handling and braking performance. Under-inflated tires can lead to increased wear, reduced traction, and the risk of blowouts, all of which compromise safety.

Moreover, maintaining the correct tire pressure contributes to fuel efficiency. When tires are inflated to the manufacturer's recommended levels, the vehicle experiences less rolling resistance, subsequently improving gas mileage. Conversely, if tire pressure is too low, the engine must work harder to maintain speed, leading to higher fuel consumption.

The other options do not pertain to the primary reasons behind checking tire pressure. Tire color, the age of the tires, and the vehicle's speed rating are not directly relevant to the inspection of tire pressure, which primarily focuses on safety and performance on the road.
