Quick Answer
Replacing all 4 tires does not necessarily require an alignment, but an alignment is usually recommended. When you get new tires, even if they are the same size, they can change the alignment of your vehicle. An alignment helps make sure your new tires wear evenly and properly.
What is a Wheel Alignment?
A wheel alignment (also called an alignment) refers to adjusting the angles of the wheels so they are set to the manufacturer’s specifications. The main angles adjusted are:
- Camber – the angle of the wheel inward or outward from vertical.
- Caster – the angle of the steering pivot from vertical.
- Toe – the angle of the wheels toward or away from each other.
Proper alignment helps optimize handling, stability, steering response, and tire life. Out of alignment wheels can cause uneven tire wear, reduced fuel economy, and handling issues.
Do You Need an Alignment When Replacing Tires?
Getting an alignment when installing new tires is usually recommended for a few key reasons:
- New tires may be shaped differently – Even if you purchase the same size and model tire, variations in tire construction can affect alignment.
- Riding on misaligned tires wears them out – An existing alignment issue will quickly wear out the new tires if not corrected.
- Alignment maximizes tire life – Aligning the wheels helps get the full lifespan out of your new tires.
- Safety – Poor alignment can make vehicles harder to control and less stable on the road.
Although an alignment is not required every time you replace tires, doing so is considered a best practice. Many tire shops include alignments with tire installation packages.
When Can You Skip an Alignment?
Here are some cases when you may be able to install new tires without an alignment:
- You recently had an alignment – If your alignment was checked within the past 6 months or so, it may still be within specifications.
- Tires are the same size – Installing the exact same tire size and model on the same wheels has less chance of changing alignment.
- No alignment issues – If the previous tires showed relatively even wear, your alignment is likely fine.
- Low mileage vehicle – Brand new vehicles that have seen very little use are unlikely to be out of alignment.
Keep in mind that unless you have confirmation of a recent alignment, it’s hard to be sure the wheels are still aligned properly. Getting an alignment check is the only way to verify.
The Benefits of Aligning Wheels
Here are some of the key benefits you can gain from having an alignment performed when you get new tires:
- Enhances driving comfort – Correct toe settings keep the steering wheel centered and easier to control.
- Prevents uneven tire wear – Alignment keeps tires wearing evenly for their full lifespan.
- Improves fuel economy – Less drag from misaligned wheels improves gas mileage.
- Restores handling and stability – Aligning the wheels can correct wandering, pulling, and other issues.
- Reduces vibration – Wheels that are in and out of alignment can cause vibration through the steering wheel and suspension.
How Much Does a Wheel Alignment Cost?
Alignment costs can range from $50 – $150 or more, with an average of around $75-100 per axle. Cost depends on the vehicle, alignment shop, and your location. Many tire and alignment shops offer package deals that include the cost of alignment when purchasing new tires.
Here are some typical alignment cost estimates:
| Service | Average Cost |
| 2-wheel alignment | $50-$75 |
| 4-wheel alignment | $75-$150 |
High-end wheel alignments with an extensive adjustment procedures cost over $200 in some cases.
Do Tires Affect Alignment?
Yes, tires can definitely affect wheel alignment. Some of the ways new tires impact alignment include:
- New tires come with their own shape – Tire construction specifications, even for the same sizes, can alter wheel orientation.
- Wear affects tire shape – As tires wear down, their shape often changes slightly, affecting alignment.
- Different brands have different specifications – Changing tire brands or models may require adjustment to restore proper alignment.
- Irregular wear changes shape – Uneven tire wear from misalignment causes shape changes that further impact alignment.
These variables make it smart to have an alignment check whenever you replace tires. Even if you stay with the same tire, wear and slight differences in construction make the wheels and tires work together differently.
Signs You Need a Wheel Alignment
Here are some common signs your vehicle likely needs an alignment service:
- Vehicle pulling to one side
- Steering wheel off center while driving straight
- Tires wearing unevenly
- Reduced gas mileage
- Vibration in steering wheel or seat
- Squealing tires
- Car drifts or wanders on straight road
- Tires showing toe wear
Any of these alignment symptoms point to a need to have your wheels realigned and can lead to accelerated tire wear if left unaddressed.
Ask the Mechanic to Check Other Components
When having your wheels aligned, consider asking the mechanic to check the following related components:
- Tire inflation – Low pressure affects handling and suspension.
- Tire condition – They can inspect tires for damage and wear.
- Wheel bearings – Listen for noises indicating worn bearings.
- Steering and suspension – Inspect for loose joints or damaged components.
- Shocks and struts – See if they need replacement to improve handling.
Checking these related parts helps maximize the benefits you get from the alignment. Fixing issues early prevents accelerated wear and damage down the line.
How Often Should You Get an Alignment?
Manufacturers usually recommend getting your wheels aligned at regular intervals, such as:
- Every 6,000-8,000 miles
- Once a year
- With new tires
- After hitting potholes
- When experiencing alignment symptoms
More frequent alignments may be needed for vehicles in rough conditions like on construction sites or rural roads. Keeping alignment in check helps prevent uneven wear that shortens tire life.
Can You Adjust Alignment Yourself?
DIY alignment adjustment is generally not recommended. While you can purchase alignment tools, getting angles within factory specifications takes specialized equipment and experience. Poor DIY alignment could accelerate tire wear and create safety issues.
However, you can take steps to tell if your vehicle needs alignment:
- Check tire wear – Inside or outside edge wear indicates alignment issues.
- Test drive for pulling, wandering, etc.
- Measure tread depth – Uneven wear is a sign of alignment problems.
Leave actual alignment adjustments to certified technicians to make sure it is done correctly. Inform them of any symptoms you noticed on your test drive.
Tips for Maximizing New Tire Life
Besides keeping alignments up to date, here are some tips for making your new tires last:
- Maintain proper tire pressure
- Rotate tires regularly
- Inspect tires for damage
- Avoid potholes and curbs
- Drive at moderate speeds
- Balance your wheels
- Check suspension and steering parts
Following the manufacturer’s maintenance schedule helps your tires — and your alignment — stay in top shape. Keep an eye out for any symptoms of misalignment or tire wear.
Conclusion
While an alignment is not absolutely required each time you get new tires, it is highly recommended in most cases. Having your wheels properly aligned helps maximize the life of your tires and ensures optimal handling and safety. The relatively minor cost of an alignment is a wise investment to protect the more expensive purchase of replacement tires. Keeping your tires and alignment maintained provides performance, safety and savings down the road.
