You might not think about your car’s wheel alignment every day, but it plays a critical role in the health of your vehicle. Proper wheel alignment ensures your tires wear evenly, your vehicle handles safely, and your fuel efficiency stays optimized. Unfortunately, many drivers aren’t aware of the impact that poor wheel alignment can have until it starts causing noticeable issues.
At Express Auto/RV Care Center, we’re here to help you understand how alignment affects not only your tires but also your fuel efficiency—and how keeping your alignment in check can save you time, money, and frustration in the long run.
What Is Wheel Alignment?
Before we dive into how misalignment affects your car, let’s clarify what we mean by “wheel alignment.” Wheel alignment refers to adjusting the angles of your vehicle’s wheels so they meet the manufacturer’s specifications. When your wheels are properly aligned, they are perfectly positioned to contact the road at the correct angle.
There are three main aspects of alignment:
- Camber: This is the angle of the tires when viewed from the front of the vehicle. If the top of the tire tilts inward or outward, this indicates improper camber alignment.
- Toe: This refers to the direction your tires point when viewed from above. Imagine your car’s tires are your feet—when the tires point toward each other, this is called “toe-in.” When they point away from each other, it’s called “toe-out.”
- Caster: Caster refers to the angle of the steering axis when viewed from the side of the vehicle. Caster affects steering stability and how the car handles at higher speeds.
When these angles are even slightly off, you can experience a range of problems, from uneven tire wear to poor fuel efficiency. Let’s explore how poor alignment affects these areas and more.
How Poor Wheel Alignment Affects Your Tires
Your tires are the first point of contact between your vehicle and the road, and they play a vital role in your car’s overall performance. When your wheels are misaligned, your tires can suffer from uneven wear, reducing their lifespan and performance.
1. Uneven Tire Wear
One of the most obvious signs of poor alignment is uneven tire wear. When your wheels aren’t aligned correctly, certain parts of the tire bear more weight and friction than others. This causes some areas of the tire to wear down faster than the rest, which can lead to premature tire replacement.
For example, if your car’s camber alignment is off, you may notice that the inside or outside edges of your tires are wearing out more quickly than the middle. This uneven wear not only shortens the life of your tires but can also lead to safety issues, as worn tires don’t grip the road as well as evenly worn ones.
2. Increased Risk of Blowouts
As your tires wear unevenly, they become more vulnerable to blowouts, especially when you’re driving at high speeds or on rough roads. A blowout occurs when a tire rapidly loses air pressure, which can cause you to lose control of your vehicle.
Maintaining proper alignment helps distribute the wear evenly, reducing the risk of blowouts and ensuring your tires perform optimally.
3. Poor Traction and Handling
When your tires are worn unevenly due to poor alignment, you may notice that your car doesn’t handle as well as it should. Poor alignment can make your vehicle feel unstable, especially when turning or driving at higher speeds. This is because misaligned wheels reduce the contact area between your tires and the road, decreasing traction and control.
In wet or slippery conditions, this lack of traction becomes even more dangerous. Proper alignment helps maintain full contact with the road, ensuring your car handles smoothly and safely in all driving conditions.
How Poor Wheel Alignment Affects Fuel Efficiency
Most people don’t realize that poor wheel alignment can also have a significant impact on fuel efficiency. When your wheels are misaligned, your car has to work harder to move, which means it consumes more fuel. Here’s how:
1. Increased Rolling Resistance
Rolling resistance is the friction that occurs between your tires and the road as they roll. When your wheels are properly aligned, this resistance is minimized, allowing your car to glide smoothly and efficiently.
However, when your wheels are misaligned, they create additional friction or resistance as they fight to stay on the road. This increased resistance forces your engine to work harder to maintain speed, which results in higher fuel consumption.
2. Drag from Misalignment
Misaligned wheels can create drag, which is essentially the force that opposes your car’s motion. When your wheels aren’t pointing in the same direction, your car isn’t moving as efficiently as it should. Even if the misalignment is minor, it can cause your engine to work harder, burning more fuel in the process.
This drag reduces your miles per gallon (MPG), meaning you’ll spend more money at the gas pump than you would with properly aligned wheels. Over time, these extra trips to the gas station can add up significantly, making alignment not only a safety concern but a financial one as well.
Signs Your Car Needs a Wheel Alignment
Now that we know how poor alignment affects your tires and fuel efficiency, how do you know if your car is misaligned? Here are some common warning signs that it’s time for a wheel alignment:
1. Your Car Pulls to One Side
One of the most common symptoms of poor alignment is your car pulling to the left or right when driving straight. If you find yourself constantly adjusting the steering wheel to keep the car going straight, it’s a clear sign that your wheels are misaligned.
2. Uneven or Rapid Tire Wear
As mentioned earlier, uneven or accelerated tire wear is a telltale sign of poor alignment. Regularly check your tires for signs of uneven wear, such as more wear on one side of the tire than the other.
3. Steering Wheel Isn’t Centered
When driving straight, your steering wheel should be perfectly centered. If you notice that the steering wheel is off-center, even by a small amount, it’s likely that your alignment is off.
4. Vibrating Steering Wheel
If your steering wheel vibrates or shakes while driving, it could be due to misaligned wheels. This happens because the tires are pulling in opposite directions, causing a vibration through the steering system.
5. Noisy or Squealing Tires
Tires that are out of alignment may produce unusual noises, especially when turning or driving at higher speeds. If you hear squealing or humming from your tires, it’s a sign that they’re not properly aligned with the road.
Benefits of Regular Wheel Alignments
Keeping your wheels properly aligned offers several benefits that go beyond just improving your tire life and fuel efficiency. Here are some additional reasons to schedule regular alignments:
1. Enhanced Safety
Proper alignment ensures that your car handles smoothly and predictably, reducing the risk of accidents. A well-aligned car has better traction, stability, and control, making it easier to navigate turns, curves, and sudden stops.
2. Improved Driving Comfort
Driving a car with misaligned wheels can be frustrating and uncomfortable. You may find yourself constantly correcting the steering wheel or dealing with a bumpy ride. Regular wheel alignments help provide a smoother, more enjoyable driving experience.
3. Cost Savings
While getting your wheels aligned may seem like an added expense, it can actually save you money in the long run. By extending the life of your tires and improving fuel efficiency, regular alignments help reduce the need for premature tire replacements and extra fuel costs.
When to Schedule a Wheel Alignment
So, how often should you get a wheel alignment? The general rule of thumb is to have your alignment checked at least once a year, but there are several factors that can impact how often you need one, including:
- Hitting potholes, curbs, or road debris
- Driving on rough or uneven roads
- Installing new tires
- After suspension or steering repairs
If you notice any of the warning signs mentioned earlier, it’s a good idea to schedule an alignment check sooner rather than later.
