Wheel alignment, often called tire alignment, is a crucial maintenance procedure that adjusts your vehicle’s suspension system rather than the wheels themselves. This adjustment ensures that your tires meet the road at the correct angle as specified by the manufacturer. Proper alignment is vital for optimal handling, tire longevity, and overall driving safety. According to the National Highway Traffic Safety Administration (NHTSA), misalignment is a significant factor in premature tire wear and can contribute to accidents.
1.1. What Exactly is Adjusted During an Alignment?
During a wheel alignment service, technicians focus on adjusting three key angles:
- Camber: The camber angle is the inward or outward tilt of the tire when viewed from the front of the vehicle. Excessive positive or negative camber can lead to uneven tire wear.
- Caster: The caster angle is the angle of the steering axis when viewed from the side of the vehicle. It affects steering stability and handling.
- Toe: The toe angle is the direction in which the tires point relative to each other. It can be “toe-in” (pointing towards each other) or “toe-out” (pointing away from each other). Incorrect toe angles can cause rapid tire wear and steering problems.
1.2. Why is Proper Wheel Alignment Important?
Proper wheel alignment offers several significant benefits:
- Extended Tire Life: Correct alignment ensures that your tires wear evenly, maximizing their lifespan.
- Improved Fuel Efficiency: When your wheels are properly aligned, your car requires less energy to move, resulting in better gas mileage.
