The tires of your vehicle play a crucial role in the overall comfort and safety of the vehicle. The unbalanced tire is one of the most commonly encountered issues that can arise while your car is in the garage or driving on the road. Learn the symptoms of unbalanced tires.
Tire unbalancing is a situation where the tires of your car are not level with each other. Maintaining the good health of your car’s tires is vital for your safety while driving. Therefore, it’s essential to recognize the signs of unbalanced tires.
Having a good understanding of the symptoms of imbalanced tires can be a valuable asset, enabling you to address the issue before it becomes more severe. This article explains the unbalanced tire symptoms, causes, and how to fix them.
What Is Tire Balancing?
Tire balancing ensures that the weight of your tire and wheel assembly is evenly distributed. Even brand-new tires and wheels can have slight variations in weight that cause them to spin unevenly at high speeds.
Small counterweights are attached to the wheel rim during a tire balancing service to offset any imbalances. This ensures the tire rotates smoothly, reducing vibrations and uneven wear.
What is an Alignment?
An alignment is the process of adjusting the angles of your vehicle’s wheels so they are all working together on straightaways and corners.
Everyday driving can cause your wheels to get slightly out of sync from one another. That can be especially true if you hit a few curbs or potholes.
When one or more of your wheels isn’t pointing in the same direction, your tires are essentially skidding ever so slightly. This can lead to faster tire wear, pulling to one side or the other, a steering wheel that’s off-center, and loss of fuel or range economy.
What Causes Unbalanced Tires?
Unbalanced tires may be caused by different factors such as weather, poor tire pressure, damaged axle, damaged wheel, loss of tire weight, tire wear, or poor alignment of the wheels.
These causes are properly explained below:
#1. Poor Tire Pressure.
Poor tire pressure is one of the major causes of the unbalanced tires. It’s crucial to maintain proper tire inflation by adhering to the manufacturer’s instructions.
When one tire of your vehicle is underinflated, the vehicle’s balance is compromised, causing it to lean toward the affected wheel.
You may also face the same issue when some tires are over-inflated. To ensure correct tire pressure, refer to the manufacturer’s recommended limits.
#2. Worn Tires.
The worn-out tires are considered a major cause of unbalanced wheels or tires. The tires of your car constantly make contact with various roads, which can lead to accelerated wear.
When your tires wear out, irregular shapes develop on the tire body, potentially causing imbalance.
When dealing with worn-out tires, it’s recommended to consider tire rotation. This maintenance procedure not only helps restore tire balance but also extends its lifespan. Additionally, it’s important to regularly inspect tire pressure to ensure sufficient pressure.
#3. Damaged Axle and Wheel.
Sometimes, you can encounter a suspension issue, possibly because of wheel or axle damage, such as a bent or broken axle.
When your vehicle encounters issues related to the suspension system, one of your tires won’t be in line with the others, and you might experience difficulty in steering or hear unusual noises while driving.
#4. Loss of Tire Weight.
Another factor contributing to imbalanced tires is the loss of tire weight, which plays a critical role in maintaining the tire’s stability and balance.
The factors that may cause the loss of tire weight include encountering potholes or hitting speed bumps at high speeds. When tire weight is lost, the affected tire can deform or deflate, leading to unbalancing.
#5. Weather.
Weather conditions, particularly cold temperatures, can contribute to tire imbalance. Cold weather leads to the contraction of air particles, potentially causing tire deflation.
This deflation can occur unevenly, affecting some tires more than others and resulting in an imbalance.
#6. Poor Alignment.
Poor alignment of the wheels is also one of the major causes of unbalanced wheels. The wheel alignment involves adjusting the suspension system of a vehicle to ensure proper tire angles as they make contact with the road.
If this procedure is not performed accurately, it can result in wheel balancing problems.
Symptoms of Unbalanced Tires
After looking at the probable causes of unbalanced tires, here are some symptoms of the issue you should know.
#1. Uneven Tire Wear.
Uneven tire wear is one of the earliest and most visible signs of unbalanced tires. When a tire is unbalanced, certain areas experience more pressure than others, leading to irregular wear patterns.
For example, you might notice excessive wearing on one side of the tire while the other appears untouched.
Feathered or scalloped edges are also clear signs of an imbalance. These problems can reduce the lifespan of your tires significantly, forcing you to spend more money to replace them more frequently and get a worse return on your investment.
Regularly inspecting your tires for uneven wear can save you from costly replacements and ensure your car maintains optimal performance.
#2. Vibrations in the Steering Wheel.
If you’re feeling vibrations in your steering wheel while driving, particularly at speeds between 50 and 70 mph, unbalanced tires might be the culprit.
Uneven weight distribution in one or more of the tires causes these vibrations, which throws off the wheel’s rotational symmetry.
What makes this even more alarming is that similar vibrations can stem from other faults, such as misaligned suspension or failing wheel bearings.
To confirm whether the tires are to blame, consider when the vibrations occur. If they’re worse at higher speeds and seem to lessen when you slow down, it’s likely an issue of tire imbalance.
#3. Vibrations in the Seat and Floor.
While a driver may feel steering wheel vibrations up front, unbalanced rear tires can cause noticeable vibrations that radiate through the seat and floor of your car. These vibrations are not simply a nuisance; they can affect your comfort and concentration while driving.
Worse, continued driving with unbalanced tires can wear out other components of your car, such as shocks, struts, and bearings. Addressing these vibrations early can save you from additional repairs and costs further down the line.
#4. Increased Fuel Consumption.
Another sign that your tires may be unbalanced is if your vehicle’s fuel economy dips below its typical consumption.
Uneven tires create additional rolling resistance, meaning your car needs to work harder to maintain speed and stability. Over time, this added effort leads to a noticeable decrease in miles per gallon.
While the loss of fuel economy won’t be significant, it’ll still be noticeable, especially if you haven’t changed any of your driving habits or patterns.
If you notice your vehicle’s fuel economy is dipping as of late, consider checking your tires and ensuring they’re properly balanced.
#5. Vehicle Pulling to One Side.
Another common symptom of unbalanced tires is a car that pulls to one side, especially on straight roads. While pulling can also occur due to issues like wheel misalignment or improper tire pressure, unbalanced tires are a frequent cause.
This imbalance forces your tires to exert unequal forces on the ground, which tugs your car in one direction. Ignoring this issue can lead to premature tire wear and make it uncomfortable—and unsafe—to drive.
If you notice consistent pulling, it’s important to get your tires checked right away before more serious issues develop.
#6. Thumping Sound from Tires.
Hearing an irregular thumping or bumping sound while driving is more than just an annoyance—it’s likely a warning sign of tire imbalance.
These sounds result from the uneven distribution of weight within the tire, causing it to hit the road inconsistently. This thumping noise typically grows louder at higher speeds, making highway driving particularly unpleasant.
If you don’t address this problem immediately, the condition will worsen over time and lead to more substantial damage to your tires and suspension system. A quick visit to your mechanic or tire specialist can ensure prompt and efficient resolution of this issue.
#7. Increased Road Noise.
If your usual drive suddenly seems louder than normal, your tires could be to blame. Unbalanced tires often create excess road noise due to uneven weight distribution, generating more friction and reverberance.
This noise is especially noticeable on less-than-ideal road surfaces or when driving at higher speeds. While some road noise is inevitable, a clear and sudden increase could indicate an underlying imbalance.
The good news is that fixing this issue through tire balancing will restore quiet and comfort to your rides.
#8. Bad Shocks and Bearings.
Long-term driving with unbalanced tires doesn’t just damage your tires; it places added strain on other vital components of your vehicle, including shocks and bearings.
Shocks act as a cushion to your car, absorbing impact and ensuring smooth rides, while bearings help your wheels rotate freely.
Since unbalanced tires result in uneven force distribution, they can wear these parts out prematurely. Replacing shocks or bearings is much more expensive than addressing tire imbalance early on, so scheduling timely tire maintenance is a wise preventive measure.
How to Fix Unbalanced Tires?
Driving with an unbalanced tire is very dangerous. Therefore, it is recommended to fix the unbalanced tires as soon as possible. Before balancing the tires, you must have all the necessary tools.
If you are also facing tire balancing issues, follow the below-given steps to balance your car tires:
- Park Your Vehicle: Park your vehicle on a level surface and turn off your engine.
- Identify the Issue: Start by finding the main issue causing the tire to be imbalanced. You also need to find which tire is unbalanced.
- Lift Your Car: Lift your car by using a jack to remove the wheel for tire balancing.
- Remove the Imbalanced Tire: Now, it’s time to remove the affected tire using a socket set or a lug wrench.
- Balance the Tires: Contact a professional mechanic who has the tire balancing machine. Your mechanic will utilize different methods (like weights or computerized balancing) to balance your tire.
- Install Counterweights: To balance your tire, your mechanic will usually connect small counterweights to your wheel to ensure its proper balancing.
- Reinstall the Tire: When your tire is balanced, the mechanic will reconnect it to your car and retighten the lug nuts properly.
- Lower the Vehicle: After installing the balanced tire, it’s time to lower your vehicle and perform a test drive to check balancing.
Tire Balance vs. Wheel Alignment
Wheel alignment and tire balancing are two different services. However, many people think they are the same. Although both may produce similar symptoms, but they address various problems.
The main difference between wheel alignment and tire balancing lies in their objectives. The wheel alignment focuses on ensuring that the wheels are parallel to each other and perpendicular to the road surface. However, tire balancing focuses on achieving even weight distribution around the tire.
In simple wording, in the tire balancing process, wheel assemblies and the weight imbalances in your tire are corrected, whereas, in the wheel alignment, the angles of the tires are corrected to ensure they make proper contact with the ground.
Unbalanced Tires: Tire Balancing Cost
So, now that you’ve verified that you have unbalanced tires, how much will it set you back to perform a tire balancing? Thankfully, not a lot.
In most cases, tire balancing costs about $10 per tire. You can do only the front or rear tires if you like. But ideally, you should do all four at once, so that brings the cost to $40 in total.
Keep in mind that certain wheel and tire sizes may cost more. You can expect a tire balancing to cost up to $80 for some cars. But regardless of your tire and wheel size, the labor cost is already built-in to this price.
The process entails taking off the wheels from your car. Afterward, the technician will put the tires into the balancing machine to check the rotation. They’ll install, move, or remove the wheel weights appropriately until the machine says the tire’s rotation is balanced.
Our tip is to ensure that there are no hidden costs to the job. Some tire shops may do a suspension and wheel checkup without telling you and then charging you for the job.
If you don’t want to pay any more than you have to, ensure that they won’t do this and won’t charge you any extra fees. However, there’s nothing wrong with having your wheels, tires, and suspension checked while doing a tire balancing job.
FAQs.
Q: What Happens If You Drive On Unbalanced Tires?
Driving on unbalanced tires is quite rough as you may notice noises from the engine or the suspension system. It may replicate on the steering system where the steering wheel will be unstable and start to vibrate.
Among the secondary factors that might come from the problem include damage to other car parts, mostly the suspension system. In serious cases, particularly when driving at high speeds, it may lead to a loss of control and cause accidents.
Q: Do Unbalanced Tires Affect Alignment?
While unbalanced tires do not directly affect alignment, they can come in the way of wheel angling. If you drive the car for long on unbalanced tires, it may appear unaligned and cause problems with the suspension and steering system.
Q: Do All Four Tires Need To Be Balanced?
Yes, for the perfect equilibrium, you should balance all the tires. After balancing, perform wheel alignment of the occasional tire rotation for a smooth session when on the road.
Q: How Do I Know If I Need Alignment Or Balance?
Alignment vs. balance is one area that confuses many people, and they may wrongly use the words interchangeably. Alignment refers to adjusting the wheels’ angles according to manufacturer specifications, and you can perform it less regularly than tire balancing.
On the other hand, tire balance seeks to make the individual tires level for them to gain the ideal equilibrium. You should perform alignment regularly to extend the life of the tires.
Final Word
The symptoms of unbalanced tires are mostly too subtle for the average driver to notice. Things like increased tire noise, increased fuel consumption, and increased tread wear will fly under the radar in most cases.
But if the balancing is that bad, the tires will cause severe vibrations which is the main symptom of unbalanced tires.
Unfortunately, it’s a symptom of other faulty suspension components so have the suspension inspected first, and if everything looks good, move on to balancing the tires. And if that doesn’t help, get a wheel alignment.
