What is the purpose of a wheel alignment?

1. To adjust tire pressure for better traction

2. To adjust the angles of the wheels for handling and tire life

3. To balance the weight of the vehicle evenly

4. To ensure the vehicle's oil levels are correct

The correct answer is: To adjust the angles of the wheels for handling and tire life

The purpose of a wheel alignment is fundamentally to adjust the angles of the wheels so that they are set to the vehicle manufacturer's specifications. Proper wheel alignment is crucial because it directly affects handling, safety, and tire life. When the wheels are aligned correctly, it allows the vehicle to track straight and true down the road, which enhances steering response and improves the overall driving experience. Moreover, correct alignment helps to minimize tire wear. Misalignment can lead to uneven tire wear, which means that tires may need to be replaced sooner than expected, resulting in additional costs for the vehicle owner. In addition to the handling and tire longevity benefits, a proper alignment can also contribute to better fuel efficiency. When the wheels are aligned correctly, the vehicle experiences less rolling resistance, which can improve fuel economy. While adjusting tire pressure is important for traction, ensuring the vehicle's weight distribution is even, and monitoring oil levels are essential maintenance tasks, they do not directly relate to the specific purpose of wheel alignment. Thus, the focus of wheel alignment is specifically on the angles and positioning of the wheels in relation to each other and the car's body.
