It is very much possible that even the tiniest kind of misalignment in your wheels can silently eat away your tires, your fuel and your wallet as well: which is very important to keep everything balanced, smooth and safe.
Because of the importance of wheels: even the car alignment also known as the wheel alignment as well: as it adjusts the vehicle’s suspension system that controls how the tires actually makes the contact with the road.
And that’s why proper alignment is actually needed to ensure that the wheels are set to the manufacturer’s precise angles of camber, caster and toe: and it directly affects the steering stability, tire wear and fuel efficiency as well.
Along with this, studies also shows that even a small misalignment of just 0.34 degrees can actually drag a tire sideways up to the 68 feet for every mile driven, which later leads to the faster tire wear and wanted fuel as well.
And according to the U.S. Department of Energy, poor alignment can actually reduce the fuel economy by up to 10%.
Even, drivers often overlook the alignment until the handling problems become unavoidable anymore, but car experts recommends the you need to check it at least every 6,000 to 10,000 miles.
So, you need to check for alignment as it is not just the matter of comfort that you can compromise but it is more about the safety, saving money and extending the life of your tires and suspension system as well and this guide literally about How to Check Car Alignment, so that you can have precise techniques about it.
What are The Common Symptoms of Bad Alignment
1. Uneven or Rapid Wear of Tires
One obvious sign of bad alignment is that your tires wear unevenly.
Instead of the tire tread wearing evenly, you may notice bald spots on the inner or outer edges.
This happens because the wheels are tilted at the wrong angle, causing the tire to wear more on one side.
According to the Rubber Manufacturers Association, misalignment can reduce tire life by up to thirty percent.
Regularly checking your tires for unusual wear patterns can help you spot alignment problems before they damage all four tires.
2. Vehicle Pulling to One Side
If you’re trying to drive straight on a level road and your car leans to the left or right, this is often a sign of misalignment.
This pulling happens because the wheels aren’t pointed in the same direction, causing the vehicle to wobble.
Drivers may think it’s just the road surface, but if the grip is the same on different roads, it’s almost always an alignment problem.
Not only is driving tiring, but it also increases fuel consumption because the engine has to work harder to keep the car straight.
3. Steering wheel crooked when driving straight
The steering wheel not being centered when driving in a straight line is another easily recognizable symptom.
In a properly aligned car, the steering wheel should be level and pointing straight ahead.
If the car appears crooked or tilted even when driving straight, it indicates that the wheels are not aligned.
It may seem like a small thing, but it can lead to reduced handling control and put extra stress on steering components, causing them to wear out faster.
4. Steering wheel vibration
Misaligned wheels can also cause vibrations that you can feel through the steering wheel.
These vibrations are usually caused by tires not riding smoothly due to uneven contact with the road.
Sometimes drivers mistake this for unbalanced tires, but alignment problems are another common cause.
Constant vibrations not only make driving uncomfortable, but also increase the risk of steering parts coming loose over time.
5. Tires squealing when cornering
If you hear squealing or squealing noises from your tires when cornering, this could be another warning sign of poor alignment.
This noise occurs because the tires are being forced to ride at an unnatural angle, creating extra friction with the road surface.
Over time, this can cause the tires to overheat and wear out faster.
Tire squealing is not only annoying, but also a safety concern, as it indicates that your car is not handling turns as well as it should.
Visual Inspection at Home
1. Check the Wear Pattern of the Tires
Tires reveal a lot about your car’s alignment.
If the wheels aren’t properly aligned, the tread won’t wear evenly across the tire’s surface.
For example, when the inner or outer edges of tires wear faster than the center, it often means that the camber angle is out of whack.
If you see a feathered or saw-toothed pattern on the tread, it usually points to incorrect toe alignment.
According to the Tire Industry Association, uneven tire wear is one of the most reliable signs of misalignment and ignoring it can reduce tire life by thousands of miles.
Checking your tires’ wear regularly, specially every few weeks or during a regular car wash, can save you from costly tire replacements later.
2. Check the steering wheel position
The center steering wheel is another easy way to know if your alignment is in the right position.
When you drive on a straight, level road, the steering wheel should be level, pointing straight ahead.
If the car is driving straight and the steering wheel appears to be tilted to the left or right, this is a sign that the wheels are not properly aligned.
If the alignment is off by even a little less than one degree, the steering wheel can appear crooked.
Over time, this can put stress on steering components and make your driving less precise.
Identifying this early helps prevent unnecessary wear on the suspension and improve driving comfort.
3. Check for suspension or tire problems
Before blaming the alignment alone, it’s important to check the condition of your suspension and tires.
Damaged or worn suspension components, such as ball joints, tie rods or control arms, can throw off or worsen alignment.
Likewise, under-inflated or unevenly inflated tires can also show signs of poor alignment.
Studies show that even a small drop of six psi in tire pressure can cause uneven tread wear and reduced handling performance.
By carefully inspecting your tires and suspension for visible damage, cracks or low air pressure, you can prevent simple maintenance issues from being confused with alignment problems.
4. Park on a Level Surface and Check Condition
Parking your car on a flat, level surface gives you a clear idea of your vehicle’s condition.
If the car appears to lean to one side or one wheel appears to be leaning in or out more than the other, this could be a sign of misalignment or worn suspension parts.
Professional mechanics often use alignment machines to accurately measure angles, but a quick condition check at home can also provide important clues.
For example, wheels that appear to be slightly turned in or out often indicate a toe problem, while a wheel that appears to be tilted in from the top may indicate a camber problem.
Taking a few minutes to step back and check your car’s position can help you spot problems before they become serious.
Simple Alignment Test at Home
1. Straight Line Test
One of the easiest ways to check your car’s alignment at home is to perform a straight line test.
For this, drive your car on a flat, smooth and empty road, preferably one with little or no slope at all.
While maintaining a light grip on the steering wheel, see if the car is traveling in a straight direction or leaning to one side.
A car with perfect alignment should drive smoothly without veering left or right.
If the car repeatedly leans to one side, even on different roads, it usually indicates a problem with the toe or camber angle.
Research by the Society of Automotive Engineers shows that even a slight misalignment can cause the car to tilt several feet in a short distance, affecting not only safety but also fuel consumption due to the added resistance.
2. String Test
The string test is a more practical method that has been used by mechanics and racers for years.
This test involves pulling a piece of rope tightly on either side of the car, making sure it passes at the same height over the front and rear wheels.
By comparing the distance between the rope and the wheels, you can see if the wheels are turned inward, turned outward or straight.
If the front of the wheel is closer to the front than the back of the rope, the car has a toe-in problem and if the opposite is true, a toe-out problem.
Although this method does not replace the accuracy of professional alignment equipment, it provides a surprisingly accurate way to identify misalignment at home.
Experts often recommend this test after hitting a pothole or curb, as it immediately reveals whether the wheels have moved out of place.
3. Plumb line or level test
Another easy home method of checking alignment is the plumb line or level test, which is used to check camber.
Camber refers to the tilt of the wheels when viewed from the front of the vehicle.
For this test, park your car on a level surface and place a carpenter’s level or hang a plumb line along the wheel.
If the top of the tire is tilted inward or outward toward the car, this indicates camber misalignment.
A slight camber angle is normal for handling and stability, but if the tilt is pronounced, it will cause uneven tire wear.
According to tire safety studies, incorrect camber can reduce the tire’s contact with the road by more than ten percent, increasing stopping distances and reducing overall grip.
Regular checks using a plumb line or level can help drivers spot these problems early and avoid costly damage to tires and suspension.
When to Get a Professional Alignment
1. After hitting a pothole or curb
The most common cause of misalignment is hitting a pothole or curb, even at low speeds.
The sudden impact can move the wheels out of their correct angle, affecting camber, caster or toe settings.
According to the American Automobile Association (AAA), damage caused by potholes causes billions of dollars in damage to drivers in the United States each year, with misalignment of wheels and suspension being one of the biggest problems.
Even if the car appears to run normally after the collision, small shifts in alignment can lead to uneven tire wear and steering problems over time.
Having the alignment checked immediately after hitting a pothole or curb can prevent more costly repairs later.
2. When New Tires, Suspension Parts or Steering Components Are Installed
It’s important to have a professional alignment whenever new tires, suspension components or steering components are installed on a vehicle.
Tires are designed to maintain full contact with the road surface, but if the wheels are not properly aligned, new tires will wear unevenly, faster than expected.
Similarly, new suspension parts such as shock absorbers, struts, or tie rods may slightly change the angle of the wheels, making the old alignment settings no longer accurate.
Automotive experts recommend aligning the wheels immediately after such an installation to ensure that the parts work properly and last a long time.
3. If multiple symptoms of misalignment are present
When the driver notices more than one symptom of misalignment—such as pulling to one side, uneven tire wear, twisting of the steering wheel, or squealing tires—it’s a strong indication that a professional alignment check is necessary.
Multiple symptoms usually mean that more than one alignment angle is out of standard.
Driving in this condition can make the vehicle unsafe, as braking distances increase and steering response decreases.
Research conducted by the National Highway Traffic Safety Administration shows that vehicles with poor alignment are more likely to lose traction in emergency situations.
For safety and long-term savings, a professional inspection is recommended at this stage.
4. Routine Maintenance Schedule
Even if there are no obvious signs of alignment problems, professional mechanics recommend having the alignment checked as part of routine maintenance.
Most manufacturers recommend alignment checks every six thousand to ten thousand miles, often at the same time as tire rotations or oil changes.
Regular checks ensure that minor alignment problems are corrected before they cause serious damage to the tire.
Studies have shown that proper alignment can increase tire life by up to twenty percent and improve fuel economy by reducing rolling resistance.
Following a maintenance schedule not only saves money, but also helps keep the vehicle safer and more efficient for longer.

Benefits of Correct Alignment
1. Better Handling and Safety
Proper wheel alignment directly improves a car’s handling on the road.
When the wheels are aligned to the manufacturer’s exact specifications, the vehicle responds more precisely to steering inputs, making driving more smooth and predictable.
This is specially important during sudden changes, such as swerving to avoid an obstacle or braking hard in an emergency.
According to the National Highway Traffic Safety Administration, vehicles with proper alignment maintain better stability and traction, reducing the risk of skidding or losing control.
In simple terms, alignment ensures that all four wheels work together harmoniously, giving the driver full control and safe handling.
2. Longer Tire Life
Tires are one of the most expensive consumable parts of a vehicle and misalignment can cause them to wear unevenly in a fraction of their expected lifespan.
When wheels are positioned at the wrong angle, more pressure is placed on specific areas of the tread, leading to bald spots or excessive wear on the edges.
The Tire Industry Association says that misalignment of tires can reduce their lifespan by up to thirty percent.
With correct alignment, tires maintain uniform contact with the road, which leads to even tread wear.
This not only delays tire replacement, but also ensures that tires maintain maximum grip and performance throughout their lifetime.
3. Improved fuel economy
Correct alignment also plays a vital role in improving fuel efficiency.
When wheels are misaligned, they generate additional rolling resistance as the tires are not facing the same direction.
This makes the engine work harder to move the vehicle forward, consuming more fuel in the process.
Research by the US Department of Energy shows that misalignment can reduce fuel economy by up to ten percent.
On the other hand, a vehicle with correct alignment runs smoother with less resistance, allowing the engine to use fuel more efficiently.
This means fewer trips to the petrol pump and long-term savings for the driver.
4. Less Stress on Suspension and Steering
Suspension and steering systems are designed so that they work best when the wheels are in proper alignment.
Misalignment puts uneven stress on parts such as ball joints, tie rods, shock absorbers and struts, causing them to wear out more quickly than normal.
Over time, this can lead to costly repairs and reduced vehicle performance.
With proper alignment, suspension and steering components share the load more evenly, making them last longer and work more reliably.
Automotive engineering studies have shown that reducing unnecessary stress on these parts not only prevents premature failure, but also maintains the vehicle’s original ride comfort and stability.
Conclusion – How to Check Car Alignment
It is not about just technical adjustment you have to do or maintain, but actually creates the difference between wasting fuel, tires and money or you can drive smart by having the perfectly adjusted vehicle.
Misalignment affects every aspect of driving—how smoothly the steering responds, how evenly the tires wear and even how much fuel the engine consumes.
Studies by the Tire Industry Association show that poor misalignment can reduce tire life by as much as thirty percent, while the U.S. Department of Energy reports that it can reduce fuel economy by as much as ten percent.
In addition, misalignment problems put unnecessary stress on suspension and steering components, which can require costly repairs if ignored.
The good news is that misalignment problems aren’t hard to spot if you pay attention to early warning signs like uneven tire wear, pulling to one side, or a warped steering wheel.
Simple at-home tests like the straight-line test, string test, or tire wear pattern can alert drivers to problems before they become serious.
However, professional misalignment should never be overlooked, specially after hitting potholes, replacing suspension parts, or routine maintenance every 6,000 to 10,000 miles.
By keeping an eye on alignment, drivers not only protect their investment in tires and suspension, but also make driving safer, smoother and more efficient.
In short, proper alignment isn’t just about comfort—it’s a balance of safety, savings and performance.
The more regularly it’s maintained, the longer your vehicle will perform at its best.
You actually have to maintain the tires perfectly aligned, as NHTSA also shows that you should look for the uneven tread wear on inner or outer edges, cracks and other trauma: and then you have to link them to find any potential mechanical issues that clearly will show if there’s any misalignment happens. As well as, routine inspection is also very important as it is the actual first-line screen before rotation or further service.[¹]

Frequently Asked Questions
Q1. What is a car alignment?
Answer: Car alignment, also called wheel alignment, is the process of adjusting the angles of your car’s wheels according to the manufacturer’s specifications. These angles are called camber, caster, and toe. Proper alignment ensures that the tires stay flat on the road and work together in the right direction. When the alignment is correct, your car drives smoothly, tires wear evenly, and fuel is used more efficiently.
Q2. How do I know if my car needs an alignment?
Answer: There are several signs that can help you identify a bad alignment. The most common signs include uneven wear on the tires, the car pulling to one side when driving straight, the steering wheel twisting, or vibrations in the steering wheel. If you hear the tires squealing when turning, that’s another clear sign. Even if you don’t notice these signs, experts recommend checking the alignment every six thousand to ten thousand miles, because problems can develop slowly without being obvious initially.
Q3. Can I check the alignment at home without special tools?
Answer: Yes, there are easy ways to tell if your car’s alignment is out of whack. You can do the straight line test by driving on a level road to see if the car leans to one side. You can also do the string test, in which you pull a string along the sides of the car to check if the wheels are straight. Another easy way is the plumb line or level test, which shows if the wheels are leaning inward or outward. While these tests can give you an indication, they are not as accurate as a professional alignment machine, so they should be used as a guide, not a substitute for professional service.
Q4. How often should I get my car’s alignment checked?
Answer: Most manufacturers and experts recommend checking the alignment every 6,000 to 10,000 miles. This often occurs with tire rotations or regular service visits, making it easy to remember. You should also get an alignment after driving over a large pothole, driving off the pavement, or installing new tires, suspension parts, or steering components. These events can change the angle of the wheels, even if the car is running normally.
Q5. What happens if I drive with a poor alignment?
Answer: Driving with a poor alignment can cause a number of problems over time. The most noticeable problem is uneven and rapid tire wear, which can cause you to replace tires more frequently. According to energy studies, poor alignment also forces the engine to work harder, reducing fuel economy by up to 10 percent. It also puts extra stress on suspension and steering components, leading to costly repairs later on. Most importantly, it also reduces safety as the car may not be able to steer properly during sudden turns, emergency braking or on wet roads.
Q6. Does alignment affect fuel efficiency?
Answer: Yes, alignment directly affects fuel efficiency. When wheels are not pointed in the same direction, they create extra rolling resistance. This means the engine has to expend more energy to move the car forward. Studies show that poor alignment can waste up to ten percent of your fuel. On the other hand, a properly aligned car runs more smoothly, saves fuel and reduces emissions.
Q7. Is wheel alignment the same as tire balancing?
Answer: No, alignment and balancing are two different services. Wheel alignment adjusts the angles of the wheels to ensure they sit correctly on the road. On the other hand, tire balancing ensures that the weight of the tire and wheel is evenly distributed, preventing vibrations at high speeds. Both are important for smooth driving and tire longevity, but they address different problems.
Q8. Can new tires fix alignment problems?
Answer: New tires can’t fix alignment problems on their own. If your car’s alignment is wrong, new tires will wear unevenly just like old tires. That’s why mechanics usually recommend checking the alignment when installing new tires. Correct alignment ensures that new tires last a long time and perform at their best.
Q9. How much does a professional alignment usually cost?
Answer: The cost of a professional alignment depends on the type of vehicle and whether you need a two-wheel or four-wheel alignment. In most cases, it ranges between fifty and one hundred and fifty dollars. Although it may seem like an extra expense, it actually saves money in the long run by protecting tires, suspension parts, and fuel economy.
Q10. If my alignment is slightly out of whack, can I drive safely?
Answer: If the alignment is slightly out of alignment, you may not notice any major problems right away, but the effects will add up over time. A slight misalignment of even less than one degree can cause a tire to drag sideways dozens of feet per mile of driving. This adds up fast and leads to uneven wear, poor handling and wasted fuel. For safety and economy, it’s best not to delay an alignment check, even if the symptoms seem minor.
