Ensuring your vehicle's tyres are correctly aligned and tracked is a fundamental aspect of car maintenance that many drivers overlook. While it might seem like a minor detail, proper wheel alignment and tracking can significantly impact your driving experience, your vehicle's health, and even your safety on the road. At Tadworth Tyre Specialists, with our 35 years of experience in the supply and repair of all tyres, we understand the importance of this often-underestimated service. This article will delve into why you need a tyre alignment and tracking test, the benefits it offers, and the tell-tale signs that indicate your vehicle might be due for a check-up.
What Exactly Are Tyre Alignment and Tracking?
Before we explore why these tests are necessary, it's crucial to understand what they entail. While often used interchangeably, alignment and tracking are distinct but related. * Wheel Alignment (or 'Geometry'): This refers to the angles of your wheels in relation to the car body and the road. There are three main angles to consider: camber, castor, and toe. * Camber: This is the inward or outward tilt of the top of the tyre when viewed from the front of the car. If the top of the tyre tilts inwards, it's negative camber; if it tilts outwards, it's positive camber. The correct camber ensures even tyre wear and optimal handling. * Castor: This is the angle of the steering axis when viewed from the side of the car. It affects the steering stability and the tendency of the wheels to return to the straight-ahead position after a turn. A positive castor angle is standard for most vehicles. * Toe: This refers to the direction your tyres are pointing. If the front of the tyres are closer together than the back, it's 'toe-in'. If the front of the tyres are further apart, it's 'toe-out'. Correct toe settings are vital for preventing tyre drag and ensuring straight-line stability. * Wheel Tracking (or 'Thrust Alignment'): This is often described as the parallel alignment of your wheels with each other and with the direction of travel. Imagine looking at your car from above: tracking ensures that all four wheels are pointing in the same direction, allowing the car to move forward in a straight line without any sideways 'crab' motion. If the rear wheels are not pointing straight ahead, the car is out of tracking.
Why Are Tyre Alignment and Tracking Tests Important?
Neglecting wheel alignment and tracking can lead to a cascade of problems, affecting your vehicle’s performance, your wallet, and your safety. Here’s why regular checks are essential: 1. Prevents Uneven Tyre Wear: This is arguably the most significant benefit. When your wheels are misaligned, tyres can be forced to scrub or drag against the road surface. This can lead to rapid and uneven wear patterns, such as feathering, cupping, or rapid wear on the edges or the centre of the tyre. Properly aligned wheels ensure that the tyres roll smoothly, maximising their lifespan and saving you money on premature replacements. 2. Improves Fuel Efficiency: Misaligned wheels create more friction and resistance as you drive. This increased drag means your engine has to work harder to maintain speed, consuming more fuel. Correcting alignment can lead to noticeable improvements in your car's fuel economy. 3. Enhances Steering and Handling: Proper alignment ensures that your steering is responsive and accurate. If your car pulls to one side, the steering wheel isn't centred when driving straight, or the car drifts when you release the steering wheel briefly, it's a clear indication of misalignment. Correcting these issues will result in a more comfortable and controlled driving experience. 4. Increases Safety: A vehicle with misaligned wheels can be unpredictable. It might pull sharply in one direction, especially when braking, or be more susceptible to veering off course due to road imperfections. This compromised handling can be particularly dangerous in emergency situations, increasing the risk of accidents. Properly aligned wheels contribute to a stable and predictable vehicle, enhancing overall safety. 5. Reduces Strain on Vehicle Components: Misalignment doesn't just affect the tyres. It can also put undue stress on your car's suspension components, steering system, and even the chassis. Over time, this can lead to premature wear and tear on these parts, resulting in costly repairs.
What Causes Wheel Misalignment?
Several factors can cause your car's wheel alignment and tracking to go awry: * Impacts: Hitting potholes, kerbs, or being involved in even minor collisions can knock your wheels out of alignment. * Wear and Tear: Over time, the various components of your suspension and steering systems can wear down, leading to subtle changes in wheel angles. * Adjustments: If you've had new suspension parts fitted or recent work done on your steering, it's possible that the alignment was affected. * Driving Habits: Aggressive driving, such as sharp cornering or heavy braking, can contribute to misalignment over time.
Signs That You Need a Tyre Alignment & Tracking Test
Your vehicle will often give you clues that something is amiss. Being aware of these signs can help you address issues before they become more serious: * Uneven Tyre Wear: As mentioned, this is a primary indicator. Inspect your tyres for wear patterns on the edges, centre, or specific spots. * 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, it's a strong sign of misalignment. * Crooked Steering Wheel: If your steering wheel isn't centred when you're driving in a straight line, your wheels are likely not aligned correctly. * Vibrations: While vibrations can be caused by many things, including unbalanced tyres, they can sometimes be linked to alignment issues. * Squealing Tyres: If your tyres squeal during normal cornering, it might indicate they are not pointing in the right direction.
The Alignment and Tracking Testing Process
At Tadworth Tyre Specialists, our alignment and tracking tests are carried out using advanced, state-of-the-art equipment. The process typically involves: 1. Initial Inspection: Our experienced technicians will first visually inspect your tyres and suspension components for any obvious signs of damage or wear. 2. Vehicle Assessment: The vehicle is placed on a hydraulic lift, and the wheels are fitted with sensors. 3. Data Comparison: The collected data on your wheel angles is compared against the manufacturer's specifications for your specific vehicle model. 4. Adjustments: If any deviations are found, our technicians will make precise adjustments to the suspension and steering components to bring everything back into the correct alignment and tracking. 5. Post-Test Verification: After the adjustments, a final check is performed to ensure all angles are within the optimal range.
How Often Should You Have Your Alignment and Tracking Checked?
There's no single answer, as it depends on your driving conditions and habits. However, as a general guideline, we recommend: * Annually: A routine check once a year is good practice for most drivers. * After Pothole Impacts: If you hit a significant pothole or kerb, it's wise to get your alignment checked. * After Accident Repairs: Any work involving suspension or steering components should be followed by an alignment check.
Frequently Asked Questions
Q1: How long does a wheel alignment and tracking test take?A1: Typically, a comprehensive alignment and tracking test and adjustment can take between 60 to 90 minutes, depending on the complexity and the vehicle. Q2: Is wheel alignment expensive?A2: The cost can vary, but it's generally a worthwhile investment when you consider the savings on tyre wear, fuel, and potential repairs to other components. It's a preventative measure that pays for itself. Q3: Can I check my car’s alignment myself?A3: While you can often spot obvious signs like a crooked steering wheel or uneven tyre wear, precise measurements require specialised equipment. It's best left to the professionals. Q4: My car pulls slightly to the left, is that alignment?A4: A slight pull to one side is a very common symptom of misaligned wheels. It's a good idea to have it checked. Q5: What’s the difference between wheel balancing and wheel alignment?A5: Wheel balancing corrects imbalances in the tyre and wheel assembly to prevent vibrations. Alignment corrects the angles of the wheels relative to the road and each other. In conclusion, a tyre alignment and tracking test is not just another garage service; it's a vital part of maintaining your vehicle's performance, safety, and economic running. By understanding the signs and the benefits, you can ensure your vehicle is always performing at its best.
