When to Get Your Car's Wheels Aligned

Ensuring your vehicle's wheels are correctly aligned is not just about a smooth ride; it's fundamental to your safety, the longevity of your tyres, and even your fuel economy. Many drivers overlook the importance of wheel alignment until noticeable problems arise, but understanding when and why to check it can save you a significant amount of money and hassle in the long run.

When Should You Book a Wheel Alignment?

Your vehicle's wheel alignment refers to the angles of your wheels relative to each other and to the road. Over time, these angles can shift due to everyday driving, hitting potholes, or even minor kerb impacts. When this happens, your vehicle is considered 'out of alignment', leading to several undesirable consequences.

Key Indicators You Need an Alignment Check:

• Uneven Tyre Wear: This is one of the most common and visible signs. If you notice that your front or rear tyres are wearing down unevenly – perhaps more on one side of the tyre than the other, or different wear patterns between tyres – it's a strong indication of misalignment. This uneven wear significantly shortens the lifespan of your expensive tyres.
• Increased Fuel Consumption: When wheels are misaligned, they create more rolling resistance, forcing your engine to work harder to maintain speed. This directly translates to your vehicle using more fuel than usual, costing you extra at the pump.
• Vehicle Pulling to One Side: If you find yourself constantly having to correct your steering to keep the vehicle driving straight on a flat road, it's a tell-tale sign of misalignment. The car might drift or pull noticeably to the left or right.
• Off-Centre Steering Wheel: Even when driving straight, if your steering wheel isn't perfectly centred, it suggests an alignment issue.
• Squealing Tyres: While driving, if you hear your tyres squealing, especially when turning, it could indicate that they are dragging or scrubbing against the road surface due to incorrect angles.
• Loose or Wandering Steering: If your steering feels less responsive, or if the vehicle seems to 'wander' on the road, it could be a symptom of improper alignment affecting steering precision.

Recommended Alignment Check Schedule:

Even if you don't notice any of the above symptoms, regular checks are highly recommended to prevent issues before they become serious. We advise having your vehicle's wheel alignment checked in the following situations:

• When Fitting New Tyres: This is a prime opportunity. New tyres are a significant investment, and ensuring they operate with correct alignment from day one will maximise their lifespan and performance.
• Annually or Every 12 Months / 15,000 Kilometres: Whichever comes first. This proactive approach helps catch minor deviations before they cause significant tyre wear or impact fuel economy.
• After Suspension or Steering Component Replacement: Any work involving the suspension system or steering components can alter the alignment angles. An alignment check should always follow such repairs.
• After Hitting a Pothole or Kerb: A significant impact can knock your wheels out of alignment. If you've had a particularly harsh encounter with a road hazard, it's wise to get it checked.

What is the Difference Between a Wheel Alignment and a Wheel Balance?

These two terms are often confused, but they address entirely different aspects of wheel maintenance. Both are crucial for vehicle performance and safety, but they solve different problems.

Wheel Alignment:

A wheel alignment focuses on the geometry of your car's suspension and wheels. It involves adjusting the angles of the wheels so they are parallel to each other and perpendicular to the road surface. The primary angles involved in an alignment are:

• Toe: This refers to how much the front of the tyres points inward or outward when viewed from above. Incorrect toe can cause rapid and uneven tyre wear.
• Camber: This is the inward or outward tilt of the tyre when viewed from the front of the vehicle. Incorrect camber can lead to wear on one side of the tyre.
• Caster: This angle relates to the forward or backward tilt of the steering axis when viewed from the side. It affects steering stability, cornering, and return-to-centre action of the steering wheel.

Proper wheel alignment ensures your car drives straight, handles predictably, and maximises tyre life by distributing weight evenly across the tyre's contact patch.

Wheel Balance:

A wheel balance, on the other hand, addresses the even distribution of weight around the entire circumference of the wheel and tyre assembly. Even brand new tyres and wheels can have slight weight discrepancies.

During balancing, a specialist will mount the wheel and tyre assembly on a balancing machine, which spins it to detect any heavy or light spots. Small weights are then attached to the rim on the opposite side of the heavy spots to counteract the imbalance. Balancing your wheels means your car's tyres will turn smoothly without any preventable vibrations.

An unbalanced wheel can cause vibrations that are felt through the steering wheel, the floorboards, or the seats, especially at higher speeds. These vibrations can lead to uncomfortable driving, premature wear of tyres, and stress on suspension components.

The Benefits of Professional Wheel Alignment

Investing in regular wheel alignment checks and adjustments provides a multitude of benefits for your vehicle and your wallet:

• Extended Tyre Life: Correct alignment ensures even tyre wear, meaning your tyres last longer, delaying the need for costly replacements. This is a significant factor in reducing ongoing vehicle expenses.
• Improved Fuel Efficiency: By reducing rolling resistance, your engine doesn't have to work as hard, leading to better fuel economy and lower fuel bills.
• Enhanced Driving Safety: A properly aligned vehicle handles predictably, allowing for precise steering and better control, especially in emergency situations. This contributes significantly to overall road safety.
• Smoother Ride: With wheels correctly positioned, your drive will be more comfortable, free from pulling or steering wheel vibrations caused by misalignment.
• Reduced Wear on Suspension Components: Misalignment can put undue stress on various suspension and steering components, leading to premature wear and potentially expensive repairs down the line.

Frequently Asked Questions About Wheel Alignment

Here are some common queries regarding wheel alignment:

Q: How long does a wheel alignment typically take?

A: A standard wheel alignment check and adjustment usually takes between 30 minutes to an hour, depending on the vehicle type and the extent of the adjustments required. If any seized components need to be addressed, it could take longer.

Q: Can I perform a wheel alignment myself?

A: No, wheel alignment requires specialised equipment and expert knowledge to measure and adjust the precise angles of your wheels. Attempting a DIY alignment without the proper tools and training can lead to further damage and unsafe driving conditions. It's best left to experienced professionals.

Q: How often should I balance my wheels?

A: It's recommended to have your wheels balanced whenever you get new tyres fitted, after a tyre has been repaired (e.g., a puncture repair), or if you start to notice vibrations in your steering wheel or elsewhere in the vehicle, particularly at higher speeds.

Q: Does a wheel alignment fix a car that's pulling to one side?

A: Yes, in most cases, a professional wheel alignment will correct a vehicle that is pulling to one side. However, if the pulling persists after alignment, it might indicate other underlying issues with your steering or suspension components that need further investigation.

Q: Is wheel alignment part of a standard car service?

A: Typically, a wheel alignment check is not included as a standard item in a basic car service. It's usually an additional service that needs to be specifically requested or recommended by your mechanic if signs of misalignment are observed during other inspections. Some comprehensive service packages might include it, but it's always best to confirm.

Conclusion

Don't underestimate the importance of proper wheel alignment. It's a critical maintenance task that directly impacts your vehicle's safety, performance, and running costs. By understanding the signs of misalignment and adhering to recommended check schedules, you can ensure your tyres last longer, your fuel economy remains optimal, and your driving experience is consistently smooth and safe. If you suspect your vehicle is out of alignment, or if it's simply time for a routine check, consult with experienced wheel alignment specialists.
