Misaligned wheels can hurt your car's performance, safety, and wallet. Here’s what you need to know:
Key Signs of Alignment Problems:
Causes of Misalignment:
Regular alignment checks (every 6,000–8,000 miles or annually) help avoid these issues, improve fuel efficiency, and keep your car safe. If you notice persistent problems, consult a mechanic for a professional alignment service.
Wheel alignment fine-tunes your suspension, ensuring better handling and tire contact with the road.
Alignment focuses on adjusting your suspension system - not the tires - to improve how your wheels meet the road. This adjustment helps maintain smooth handling and even tire wear.
Benefits of proper alignment include:
"Alignments help keep your wheels pointed in the right direction. When your wheels are misaligned, you may experience a few uncomfortable and potentially dangerous symptoms, such as reduced fuel economy, premature tire wear, and difficulty steering".
To better understand alignment, it’s important to know the three key angles: camber, caster, and toe.
Alignment relies on three critical angles, each playing a role in how your vehicle performs:
Camber measures how your wheels tilt when viewed from the front. Negative camber (top of the wheel tilts inward) improves cornering, while positive camber (top tilts outward) enhances stability on uneven roads.
Caster refers to the forward or backward tilt of the steering axis. Most modern cars use positive caster, where the steering axis meets the road ahead of the tire’s contact patch. This creates a self-centering effect, which keeps your vehicle steady when driving in a straight line. For performance setups, caster angles can exceed 7 degrees when paired with radial tires.
Toe alignment determines whether your wheels point slightly inward or outward compared to the centerline. This adjustment ensures your vehicle drives straight and helps prevent uneven tire wear. Professional alignment services usually cost between $65 and $100. Some shops offer lifetime packages for around $200, which include alignments every 6,000 miles.
Spotting alignment issues early can save you money on repairs and make your driving experience safer.
Uneven tire wear is a clear sign of alignment trouble. Checking your tires regularly can help you catch problems before they escalate.
"Poor alignment is a common cause of uneven tire wear... Poor alignment can shorten your tires' lifespan by thousands of miles." - Firestone Complete Auto Care
Beyond tire wear, misalignment can also affect how your car handles and steers.
If your car veers to one side while driving, it’s another sign of alignment problems. Before jumping to conclusions, check if your tire pressure is correct and if weight is evenly distributed. This issue becomes more obvious at higher speeds, making driving uncomfortable and potentially dangerous.
"The most common reason a car pulls to one side is that the wheel alignment is off." - BEMAC
A steering wheel that doesn’t stay centered when you’re driving straight is another red flag. Other related symptoms include vibration in the steering wheel, slow recentering after turns, and inconsistent responsiveness.
Pinpointing the reasons behind alignment problems is the first step to finding solutions. Knowing what leads to misalignment helps you avoid issues and keep your vehicle running smoothly.
Everyday driving puts your car at risk of hazards like potholes, speed bumps, and loose gravel. These can throw off your wheel alignment and harm suspension parts. Driving carefully can reduce these risks.
Suspension components like ball joints, shocks, struts, springs, and bushings wear down over time. This wear can lead to excessive movement and misalignment. Regular inspections are key to spotting these problems early and maintaining proper alignment.
Modifying your vehicle’s ride height or suspension system - whether through lifting, lowering, or adding aftermarket parts - can disrupt alignment. This is especially critical for modern vehicles equipped with Advanced Driver Assistance Systems (ADAS).
"When changing the ride height - the distance from the highest point on the fender well to the ground of the vehicle - by either raising, lowering or changing the relationship of front to rear, the ADAS sensors/cameras are in a different orientation than they were from the factory." - Lee Daugherty, vice president, ADAS sales and development, chief collision technology, VSG
To address this, a professional alignment service is essential to recalibrate both your wheels and ADAS sensors. For best results, aim for alignment checks every 6,000 miles.
Once you've identified alignment issues, you can attempt basic checks at home or consult a mechanic for a professional evaluation.
You can perform simple alignment checks using common household tools. These methods aren't as accurate as professional equipment but can help spot obvious problems.
String method for toe alignment:
For camber, use an angle finder to check the tire's vertical tilt. Additionally, inspect the tread for saw-tooth wear patterns: inward-pointing tread blocks suggest excessive toe-in, while outward-pointing blocks indicate too much toe-out.
If these checks show persistent problems, it's time to get a professional inspection.
You should see a mechanic if:
"If your brake pedal becomes very soft, starts to make a high-pitch squeal, or your steering wheel vibrates when you brake, then you should pull over immediately. Brakes are not something to play around with."

The cost of professional alignment services depends on the type of service and provider:
Prices can vary based on your vehicle and any added services. It's a good idea to schedule an alignment after hitting major road hazards or replacing steering or suspension parts.
Getting your wheels aligned isn’t just about keeping your car driving straight - it’s about safety, performance, and saving money. Misaligned wheels can increase stopping distances by up to 20% in bad weather and wear out tires much faster - tires meant to last 60,000 miles might only last 10,000 miles. On top of that, proper alignment can improve fuel efficiency by up to 10%, saving the average driver over $100 annually. Considering a basic two-wheel alignment service costs around $50–$100, it’s a smart way to protect your wallet and your ride.
As Barry's Auto Body puts it:
"Wheel alignment is a crucial aspect of vehicle maintenance that is often overlooked. Proper wheel alignment ensures your vehicle handles appropriately, responds predictably to steering inputs, and maintains optimal performance." – Barry's Auto Body
To keep things running smoothly, aim to check your alignment every 6,000–8,000 miles or at least once a year. It’s especially important after hitting a big pothole, getting new tires, or adjusting your suspension. While you might spot some alignment issues yourself, professional services provide the accuracy needed to ensure your car stays safe and efficient on the road. Regular checks by a pro will keep your vehicle performing at its best.
