1. Safety: Correct alignment ensures that your vehicle operates as intended, reducing the risk of accidents. When your wheels are properly aligned, your car handles better, making it easier to control, especially during emergency maneuvers or adverse road conditions.

2. Tire Wear: Proper alignment helps distribute the vehicle's weight evenly across all four tires. If your alignment is off, certain tires may bear more weight than others, leading to uneven tire wear. This can cause tires to wear out prematurely, reducing their lifespan and necessitating more frequent replacements, which can be costly.

3. Fuel Efficiency: Misaligned wheels can increase rolling resistance, meaning your engine has to work harder to move the vehicle forward. This extra effort translates to higher fuel consumption and decreased fuel efficiency. By maintaining proper alignment, you can help ensure that your car operates at peak efficiency, saving you money on fuel costs over time.

4. Handling and Performance: Correct alignment enhances your vehicle's handling and performance. When your wheels are properly aligned, your car tracks straight and true, providing better stability and a smoother ride. This is particularly important at higher speeds, as misalignment can cause steering issues and make your vehicle feel less responsive.

5. Prevent Damage to Suspension Components: Improper alignment can put additional stress on various suspension components, such as tie rods, ball joints, and bushings. Over time, this added stress can lead to premature wear and potential failure of these parts, resulting in costly repairs. By maintaining proper alignment, you help ensure that your suspension components last longer and operate effectively.

6. Alignment Check After Repairs or Modifications: Whenever you make significant repairs or modifications to your vehicle's suspension or steering system, it's essential to check and possibly readjust the alignment. Changes such as replacing suspension components, installing new tires, or lifting or lowering the vehicle can affect alignment settings. Failing to realign the wheels after such changes can negate the benefits of the repairs or modifications and lead to issues like uneven tire wear or poor handling.

7. Warranty and Long-Term Value: Some vehicle warranties may require regular alignment checks and maintenance to remain valid. Additionally, properly maintaining your car's alignment can help preserve its long-term value. When you eventually decide to sell or trade in your vehicle, having a well-maintained alignment can make it more attractive to potential buyers and increase its resale value.

Overall, regular alignment checks and adjustments are essential for maintaining the safety, performance, and longevity of your vehicle. It's a relatively simple and inexpensive maintenance task that can save you money in the long run by preventing costly repairs and improving fuel efficiency.
