Should you get a wheel alignment?

At Local Tire Guys, we’re more than just your neighbourhood tyre experts; we’re your vehicle’s best friends. And as part of our commitment to being the best in the business, we firmly believe in keeping our cherished customers informed. When it comes to the alignment of your vehicle, understanding what’s going on beneath your car can make a world of difference in ensuring its longevity and your safety. Many drivers overlook the importance of a proper wheel alignment, but it's a vital aspect of vehicle maintenance that directly impacts tyre wear, fuel efficiency, and the overall driving experience. This guide will delve into the key components of wheel alignment and help you understand when your vehicle might need this essential service.

The Fundamentals of Wheel Alignment

Wheel alignment, often referred to as 'tracking', is the process of adjusting your vehicle's suspension to meet the manufacturer's specifications. This ensures that your wheels are positioned correctly in relation to the road surface and to each other. The primary goals of a wheel alignment are to:

• Reduce tyre wear and extend the life of your tyres.
• Improve fuel economy by reducing rolling resistance.
• Enhance vehicle handling and stability.
• Ensure a smoother and safer driving experience.

Three key angles are adjusted during a wheel alignment: camber, caster, and toe. Let's explore each of these in detail.

Camber: The Tilt of Your Tyres

Imagine standing in front of your car and looking directly at your tyres. The way they lean towards or away from your car’s frame is described by the term ‘camber.’ It’s measured in degrees, and the ideal setting is typically close to 0 degrees, meaning the tyre is perfectly perpendicular to the ground. However, slight positive or negative camber is often designed into a vehicle for optimal handling.

Negative Camber

This is when the top part of your tyre leans inward, towards the car. While it can give a sporty look and improve cornering grip, an excessively negative camber can lead to uneven tyre wear, specifically on the inner edge of the tyre. This is because more pressure is concentrated on the inside tread.

Positive Camber

Here, the top of the tyre leans away from the car. Like its counterpart, too much positive camber can result in wear on the outer edge of your tyre. This occurs as the outer shoulder of the tyre bears the brunt of the contact with the road.

Proper camber adjustment ensures that your tyres have maximum contact with the road, leading to better grip, especially during cornering. When camber is out of specification, you might notice your car pulling to one side or uneven wear patterns on your tyres.

Caster: The Balance and Stability Factor

Shift your viewpoint to the side of your car. The caster angle is a bit more elusive to the naked eye but plays a vital role in your driving experience. Caster concerns the tilt of your steering axis (imagine a line running through your car’s shocks or steering pivot points). It affects how your steering wheel returns to centre after a turn and the overall stability of your vehicle at different speeds.

Positive Caster

A backward tilt of the steering axis, or positive caster, is the most common setting. It ensures stability at high speeds and contributes to the self-centring of the steering wheel, making your driving experience smoother and less fatiguing, especially on long journeys. Think of the caster angle on a shopping trolley wheel – it’s angled to trail behind, making it easier to push.

Negative Caster

A forward tilt of the steering axis is referred to as negative caster. This is less common and can lead to a feeling of looseness in the steering, particularly at higher speeds, and the steering wheel may not return to centre as effectively.

The caster angle is crucial for maintaining directional stability. If your caster is out of adjustment, you might experience a steering wheel that feels heavy, drifts to one side, or doesn't return to centre smoothly after a turn.

Toe: The Direction Your Tyres Point

For this, picture a bird’s-eye view of your car. ‘Toe’ refers to the direction your tyres point in relation to the centerline of your vehicle. It’s the angle between the tyre’s longitudinal axis and the vehicle’s centreline. Toe settings significantly impact tyre wear and how the vehicle handles during acceleration and braking.

Toe-in

If the fronts of the tyres point towards each other, it’s referred to as toe-in. This can increase stability, especially during straight-line driving, and can help keep the steering wheel centred. However, if excessive, it can lead to rapid tyre wear on the inner edges of the front tyres.

Toe-out

This is when the fronts of the tyres point away from each other. It can make your car more responsive and quicker to change direction, often used in performance vehicles. But, like toe-in, if it’s too much, it can reduce the lifespan of your tyres by causing wear on the outer edges.

Ensuring the correct toe setting is vital for balanced steering and prolonged tyre life. Incorrect toe settings are one of the most common causes of rapid and uneven tyre wear.

When Should You Get a Wheel Alignment?

Regular checks are recommended, but certain signs indicate that an alignment is definitely needed:

• Uneven Tyre Wear: If you notice wear on only one side of a tyre (inner or outer edge), or a feathering pattern across the tread, your alignment is likely off.
• Vehicle Pulling to One Side: If your car consistently drifts to the left or right when you're driving on a straight and level road, even when you're not touching the steering wheel, an alignment issue is probable.
• Crooked Steering Wheel: If your steering wheel isn't centred when you're driving straight, it’s a strong indicator that an alignment adjustment is required.
• Vibrations or Shaking: While vibrations can be caused by other issues (like unbalanced wheels), they can also be a symptom of poor alignment.
• After an Impact: If you've hit a significant pothole, curb, or been involved in an accident, your wheel alignment can be knocked out of specification.
• After Replacing Steering or Suspension Components: Any work done on these systems often necessitates a wheel alignment to ensure everything is correctly positioned.

The Alignment Process at Local Tire Guys

When you bring your vehicle to Local Tire Guys for an alignment, our trained technicians will use state-of-the-art equipment to measure and adjust the camber, caster, and toe angles according to your vehicle manufacturer's specifications. The process typically involves:

1. Inspection: A thorough check of your tyres, steering and suspension components for any damage or wear.
2. Measurement: Using laser or electronic alignment equipment to accurately measure the existing angles of your wheels.
3. Adjustment: Adjusting the suspension components to bring the camber, caster, and toe angles back into the manufacturer's recommended range.
4. Test Drive: A brief test drive to confirm the steering is centred and the vehicle tracks straight.

Understanding the Costs and Benefits

Investing in a wheel alignment is a cost-effective measure in the long run. While there is an upfront cost, it can save you money by:

• Extending Tyre Life: Properly aligned wheels ensure that your tyres wear evenly, meaning you won't have to replace them as frequently. This is often the most significant cost saving.
• Improving Fuel Efficiency: Reduced rolling resistance from correctly aligned wheels means your engine doesn't have to work as hard, leading to better miles per gallon.
• Enhancing Safety: Correct alignment ensures optimal grip and stable handling, making your vehicle safer to drive, especially in adverse conditions.

Common Misconceptions About Wheel Alignment

It's important to distinguish wheel alignment from wheel balancing. Wheel balancing addresses uneven weight distribution within a tyre and wheel assembly, which causes vibrations at speed. Alignment, on the other hand, deals with the angles of the wheels themselves.

Another misconception is that alignment is only needed when you buy new tyres. While it's a good practice to check alignment when fitting new tyres, it's crucial to have it checked regularly and whenever the signs suggest an issue.

Frequently Asked Questions (FAQ)

Q1: How often should I get my wheel alignment checked?
It's recommended to have your wheel alignment checked at least once a year, or every 10,000-12,000 miles. However, you should check it more frequently if you experience any of the symptoms mentioned above or if you've had any significant impacts.

Q2: Can I do a wheel alignment myself?
While basic 'string alignment' methods can give a rough idea, a proper wheel alignment requires specialized equipment and expertise. For accurate and safe results, it's best to have it done by a professional.

Q3: What is a four-wheel alignment?
A four-wheel alignment adjusts all four wheels of your vehicle, which is standard for most modern cars. Some older or rear-wheel-drive vehicles might only require a front-end alignment, but a four-wheel alignment is generally more comprehensive.

Q4: Will a wheel alignment fix my steering wheel shaking?
A steering wheel shake is more commonly caused by unbalanced wheels. However, if the shake is accompanied by the car pulling to one side or the steering wheel being off-centre when driving straight, an alignment issue could be contributing.
