Your car is a complex system of interworking parts. When one of these parts is damaged, it’s only a matter of time until other connected components are affected. One issue that can escalate quickly is incorrect wheel alignment. The alignment of your wheels significantly impacts your suspension and tire health.

What is Wheel Alignment?

Wheel alignment refers to the adjustment of a vehicle’s suspension—the system that connects a vehicle to its wheels. It does not involve adjusting the wheels or tires themselves. The key to proper alignment is adjusting the angles of the tires, which affects how they contact the road.

When checking your alignment, a mechanic primarily focuses on three aspects:

1. Camber: This is the inward or outward angle of the tire when viewed from the front. Excessive inward or outward tilt (negative or positive camber) indicates improper alignment and requires adjustment. Worn bearings, ball joints, and other suspension components may also contribute to camber misalignment.
2. Toe: Toe alignment refers to how much the tires turn inward or outward when viewed from above. If your toes angle inward, you have toe-in alignment; if they angle outward, you have toe-out alignment.
3. Caster: The caster angle affects steering, stability, and cornering. Positive caster means the steering axis tilts toward the driver, while negative caster means it tilts toward the front of the vehicle.

What Causes Improper Wheel Alignment?

A common cause of wheels going out of alignment is sudden impact, such as hitting a pothole or a curb. These encounters can seriously damage your car’s suspension, wheel alignment, and balancing, leading to reduced fuel efficiency and safety.

Small collisions or hitting a curb can also knock a car out of alignment. Since there may be little visible damage, drivers often overlook these issues.

Symptoms of Incorrect Wheel Alignment

In addition to uneven tire wear, there are several signs that may indicate a need for wheel alignment. These include:

• Car Pulling to One Side: To check for an alignment issue, drive on a flat surface and see if the steering pulls to either side.
• Vibrating Steering Wheel: If your steering wheel vibrates at higher speeds, it could indicate alignment problems. This may also lead to uneven tire wear or even a flat tire if not addressed promptly.
• Uneven Tire Wear: Misalignment significantly affects tire health. If your tires show uneven wear patterns, such as excessive wear on the inside or outside edges, it’s a sign of misalignment.

What is Wheel Balancing?

Wheel balancing is essential for smooth driving, safety, tire wear, and stability. It ensures that tires spin without causing vibrations. Unlike wheel alignment, tire balancing compensates for any weight imbalances in the tire/wheel combination and is often performed alongside wheel alignment.

When balancing your wheels, they should always be balanced off the car. Modern wheel balancers can perform both dynamic and static balance simultaneously. If you experience an out-of-balance condition, it’s best to have all four wheels balanced.

When Should I Consider Having My Tires Aligned and Balanced?

It is generally recommended to check your wheel alignment and balancing every 5,000–6,000 kilometers or whenever you install new tires. Don’t delay getting these services done. Visit a reputable tire fitment center that specializes in tire performance and maintenance for the best results.

Developing Trends in Vehicle Wheel Alignment and Balancing

Recent trends, such as lightweight suspension systems and lower-profile tires, have increased the need for regular alignment and balancing. Newer models are more sensitive to imbalance than older, heavier vehicles.

Improper wheel alignment and balancing can lead to handling issues, safety hazards, decreased tire tread life, reduced fuel efficiency, and negatively affect overall vehicle performance.
