Proper tire inflation affects which of the following aspects of a vehicle?

1. Engine performance

2. Vehicle safety

3. Transmission durability

4. Body integrity

The correct answer is: Vehicle safety

Proper tire inflation plays a crucial role in vehicle safety. When tires are properly inflated, they maintain optimal contact with the road, providing better traction, steering response, and overall handling. This enhances the vehicle's stability and reduces the risk of tire blowouts, which can lead to loss of control. Under-inflated tires can cause excessive wear, overheating, and may compromise the vehicle's braking performance, especially in emergency situations. While other aspects such as engine performance, transmission durability, and body integrity may be indirectly affected by tire condition, it is the overall safety of the vehicle that is directly impacted by proper tire inflation. Ensuring that tires are inflated to the manufacturer's recommended pressure is essential for the safe operation of the vehicle.
