Wheel alignment, also known as tyre alignment, is an often overlooked but crucial aspect of car maintenance. It involves adjusting the angles of the wheels so that they are parallel to each other and perpendicular to the ground. The specifications for these adjustments are set by the car manufacturer and are designed to maximize the lifespan of your tyres, improve vehicle safety, and enhance fuel efficiency. Misaligned wheels can lead to issues like uneven tyre wear, poor vehicle handling, and increased fuel consumption. Therefore, understanding wheel alignment and its importance can help you maintain your vehicle better and save on unnecessary costs.
What is Wheel Alignment?
Contrary to common belief, wheel alignment doesn’t involve adjusting the tyres or wheels themselves. Instead, it’s about fine-tuning the vehicle’s suspension, the system that connects the vehicle to its wheels. The primary goal of proper alignment is to adjust the angles of the tyres which affects how they contact the road.
The process of wheel alignment involves several steps. First, a technician will put specialized equipment on your wheels (both front and rear) that measures the alignment of your tyres. These measurements are then compared to the specifications recommended by your vehicle manufacturer for optimal tyre alignment. If the current alignment does not match the recommended specifications, the technician will adjust the alignment angles of your tyres to bring them into the correct alignment.
Why is Wheel Alignment Important?
Proper wheel alignment is important for several reasons:
- Prolonged Tyre Life: Correct alignment ensures even tyre wear, extending the lifespan of your tyres and saving you from premature replacement costs. Misaligned wheels can cause your tyres to wear unevenly and prematurely. Each tyre can wear differently, with some tyres experiencing more wear on one side or in the middle. Regular wheel alignment checks and adjustments can help your tyres last longer.
- Improved Vehicle Handling: Misalignment can cause your car to pull to one side or the other or your steering wheel to vibrate, which can make driving more difficult and less safe. Proper alignment resolves this issue, enhancing your vehicle’s handling and your overall driving experience.
- Increased Fuel Efficiency: Misaligned wheels can increase rolling resistance, which means your car has to work harder to move forward. This can lead to increased fuel consumption. By ensuring your wheels are properly aligned, you can improve your vehicle’s fuel efficiency and save money at the pump.

Signs That Your Car Needs a Wheel Alignment
Several indicators suggest your car might be due for a wheel alignment:
- Vehicle Pulling to One Side: If your car consistently veers to the left or right while you’re driving on a straight, even road, it’s a clear sign that your vehicle’s alignment is off. This can make driving more difficult and can even be dangerous if your car pulls strongly to one side.
- Uneven Tyre Wear: Regularly check your tyres for signs of uneven wear. If the tread is wearing down more on one side of the tyre than the other or if it’s wearing down too quickly, it’s likely that your wheels are misaligned.
- Off-Center Steering Wheel: When you’re driving straight, your steering wheel should be centered. If it’s off-center by more than a few degrees in either direction, you should have your alignment checked. This is a clear sign that your wheels are not aligned properly.
- Vibrating Steering Wheel: A steering wheel that vibrates while you’re driving could be a sign of wheel imbalance, which often accompanies misalignment. This can make driving uncomfortable and can be a sign of serious issues.

The Wheel Alignment Process
During a wheel alignment, the mechanic focuses on three main elements: camber, toe, and caster.
- Camber: This is the inward or outward tilt of the tyre when viewed from the front. If the top of the wheel tilts inward, that’s negative camber; if it tilts outward, that’s positive camber. Excessive camber can lead to uneven tyre wear and should be corrected. Camber misalignment can cause the tyre to wear down on one edge, and if left unchecked, can cause the tyre to fail.
- Toe: This refers to whether the fronts of the tyres are closer (toe-in) or farther apart (toe-out) than the rears when viewed from above. Incorrect toe alignment can cause your tyres to wear out prematurely. It can cause a feathered wear pattern on your tyres, which can be felt as a rough texture when running your hand along the tyre tread.
- Caster: This is the angle of your steering axis when viewed from the side. Positive caster means the top of the steering axis leans toward the rear of the car, while negative caster means it leans toward the front. Caster affects steering stability and balance. While it does not typically affect tyre wear, it can affect the vehicle’s stability at high speeds.
Proper wheel alignment is a critical aspect of vehicle maintenance that can save you money, improve your driving experience, and extend the life of your tyres. If you notice any signs of misalignment, it’s best to have your vehicle checked by a professional as soon as possible. Regular checks and adjustments can ensure your vehicle performs at its best and keeps you safe on the road. Remember, a well-aligned vehicle offers a smoother ride, better fuel efficiency, and a longer lifespan for your tyres.
