Wheel Alignment & Balancing: When to Book

Ensuring your vehicle's wheels are correctly aligned and balanced is a crucial aspect of regular car maintenance. Neglecting these services can lead to a host of problems, from uneven tyre wear and poor fuel efficiency to compromised handling and even safety concerns. This article will delve into the common indicators that suggest you need a wheel alignment and balancing, as well as the general guidelines for how often these services should be performed.

Understanding Wheel Alignment

Wheel alignment, often referred to as 'tracking' in the UK, refers to the adjustment of your vehicle's suspension components. These adjustments ensure that your wheels are set to the correct angles, which is vital for optimal tyre performance and longevity. The primary angles that are adjusted are:

• Camber: The inward or outward tilt of the tyre when viewed from the front of the vehicle.
• Caster: The angle of the steering axis when viewed from the side. It affects steering stability.
• Toe: The angle of the tyres when viewed from above. It's like the direction your tyres are pointing – either slightly inwards (toe-in) or outwards (toe-out).

Improper alignment can cause your vehicle to pull to one side, make steering feel heavy or imprecise, and significantly accelerate tyre wear.

Understanding Wheel Balancing

Wheel balancing is a process that ensures the weight is distributed evenly around the tyre and wheel assembly. Tyres and wheels are never perfectly uniform in weight. During the manufacturing process, small weights are added to counteract any imbalances. However, over time, particularly after hitting potholes or kerbs, these weights can become dislodged, or the tyre itself can wear unevenly, leading to an imbalance. An unbalanced wheel can cause vibrations, typically felt through the steering wheel or the seat, especially at higher speeds. This vibration can lead to driver fatigue, premature tyre wear, and strain on suspension components.

When Do You Need Wheel Alignment?

There are several tell-tale signs that your vehicle's wheel alignment may be off. Paying attention to these symptoms can save you money on premature tyre replacement and improve your driving experience:

1. Uneven Tyre Wear

This is perhaps the most common and significant indicator. If you notice that your tyres are wearing down more on one side than the other, or if you see feathering (where the tread blocks are worn smooth on one edge and sharp on the other), your alignment is likely out of sync. Specifically:

2. Vehicle Pulling to One Side

If you find yourself constantly having to correct your steering to keep the car travelling in a straight line, even on a level road, your alignment is likely the culprit. This can be a subtle pull or a more pronounced drift. While a flat tyre can cause this, if your tyres are properly inflated, alignment is the prime suspect.

3. Steering Wheel is Off-Centre

When you're driving on a straight and level road, the steering wheel should be perfectly centred. If it's noticeably crooked, even when you're going straight, it's a strong indication that your front wheel alignment needs adjustment. This can be due to hitting a pothole or kerb, which can knock the steering geometry out.

4. Squealing Tyres

While aggressive driving can cause tyres to squeal, if you hear squealing tyres during normal cornering, it could be a sign of misalignment. The tyres are being forced to turn at an incorrect angle, causing them to scrub against the road surface.

5. Poor Handling and Steering Feel

If your car feels less responsive, or if the steering feels loose or vague, it could be related to alignment issues. Conversely, if the steering feels overly stiff or difficult to turn, this might also point to a need for an alignment check.

When Do You Need Wheel Balancing?

Wheel balancing is usually performed in conjunction with tyre fitting or when you notice specific symptoms. Here are the key indicators:

1. Vibrations

This is the most common symptom of unbalanced wheels. You'll typically feel these vibrations through the steering wheel, especially at speeds above 50 mph. Sometimes, the vibrations can be felt in the driver's or passenger's seat. If you notice any unusual shaking or shuddering of the vehicle, it's time to get your wheels balanced.

2. Uneven Tyre Wear (Specific Patterns)

While alignment causes specific edge wear, imbalance often leads to a more generalised, patchy wear pattern, often referred to as 'cupping' or 'scalloping.' These are bald spots that appear in a circular pattern on the tyre tread.

3. Steering Wheel Shimmy

A specific type of vibration is the 'shimmy' in the steering wheel. This is a rapid, side-to-side movement of the steering wheel that occurs at certain speeds, clearly indicating an imbalance.

How Often Should You Get Them Done?

While the signs above are the most direct indicators, there are also general recommended intervals for these services:

Wheel Alignment Intervals:

• After hitting a significant pothole or kerb: This is a crucial time to check your alignment, as even a single impact can disrupt it.
• When fitting new tyres: It's highly recommended to have your alignment checked and adjusted when you fit new tyres. This ensures your new tyres wear evenly from the start.
• Every 12,000 to 15,000 miles (or annually): Many manufacturers recommend a routine check of the wheel alignment as part of your regular vehicle service. This proactive approach can prevent issues before they become noticeable or cause significant tyre wear.
• If you notice any of the aforementioned symptoms: Don't wait for the scheduled service if you experience pulling, uneven wear, or steering wheel issues.

Wheel Balancing Intervals:

• When fitting new tyres: All tyres must be balanced when they are fitted to the wheel rim.
• When refitting tyres after repair: If a tyre has been repaired (e.g., for a puncture), it should be re-balanced.
• When vibrations are felt: As soon as you notice any steering wheel shimmy or vibrations, get your wheels balanced.
• Every 6,000 to 8,000 miles: Many tyre professionals suggest re-balancing your wheels roughly every 6,000 to 8,000 miles, or at least once a year, as weights can shift over time. This is often done in conjunction with tyre rotation.

The Synergy: Alignment and Balancing

It's important to understand that wheel alignment and balancing are distinct services but are often performed together. An improperly balanced wheel can sometimes mimic symptoms of poor alignment, and vice-versa. For example, vibrations from imbalance can make the steering wheel feel 'off.' Therefore, if you're experiencing symptoms, a mechanic will often check both to diagnose the root cause accurately. It is also common practice to have both services performed when you purchase new tyres.

What Happens During the Service?

A professional wheel alignment involves placing your vehicle on a specialised lift and using laser or camera-based equipment to measure the current angles of your wheels against the manufacturer's specifications. Adjustments are then made to the suspension components (like tie rods and control arms) to bring these angles back into the correct range.

Wheel balancing involves removing the wheel from the vehicle, mounting it on a balancing machine, and spinning it to detect any heavy spots. Small counterweights are then clamped onto the rim of the wheel at precise locations to offset the imbalance, ensuring a smooth rotation.

Common Misconceptions

One common misconception is that alignment and balancing are the same thing. While both relate to the wheels and tyres, they address different issues: alignment corrects angles, and balancing corrects weight distribution.

Another is that you only need these services when something goes wrong. However, preventative checks and services at recommended intervals can save you significant money and hassle in the long run by preventing premature tyre wear and potential suspension damage.

Frequently Asked Questions

Q: How much does a wheel alignment typically cost?
A: The cost can vary depending on your location, the vehicle type, and the garage. However, a standard front-wheel alignment might cost between £50 and £100, while a four-wheel alignment could be between £70 and £150. It's always best to get a quote from your local garage.

Q: How long does a wheel alignment and balancing take?
A: A typical wheel alignment service can take anywhere from 30 minutes to an hour. Wheel balancing usually takes about 15-30 minutes per wheel. If both services are performed together, expect the process to take between 1 to 2 hours.

Q: Can I do wheel alignment myself?
A: While you can perform basic checks, precise wheel alignment requires specialised equipment and knowledge. It is strongly recommended to have this done by a qualified professional to ensure accuracy and avoid further damage.

Q: Will my insurance cover wheel alignment?
A: Typically, routine maintenance like wheel alignment and balancing is not covered by standard car insurance policies. However, if the misalignment is a result of an accident where an insurance claim was made, it might be included as part of the repair process.

Q: My car pulls to the left after hitting a pothole, what should I do?
A: This is a classic sign of misaligned wheels. You should book your car in for a wheel alignment check as soon as possible. Continuing to drive with misaligned wheels can cause uneven tyre wear and affect handling.
