Wheel alignments are one of the most important maintenance services to keep your vehicle performing at its best. Wheel alignments allow even contact with the road because all four wheels are positioned correctly.
If your vehicle is out of alignment, you may notice uneven treadwear, pulling, and an off-center steering wheel. Misalignment can also reduce fuel efficiency and shorten your tire’s lifespan.
Understanding the signs of a bad alignment can help you address problems early and avoid unnecessary tire wear.
SCHEDULE A SERVICE APPOINTMENTWhat Is Wheel Alignment?
A wheel alignment (sometimes called a tire alignment) is a service that adjusts the angles of your wheels so they match the vehicle manufacturer’s specifications.
During an alignment, technicians measure and adjust the position of your wheels to ensure they sit correctly relative to the road and each other.
Proper alignment helps:
- Keep your vehicle driving straight
- Improve steering and handling
- Reduce uneven tire wear
- Improve fuel efficiency
- Extend tire lifespan
Even minor alignment issues can affect how your vehicle handles or how quickly your tires wear down.

Signs Your Car Is Out Of Alignment
There are several common symptoms that can indicate your car needs an alignment check.
- Vehicle pulls to one side
Drifting left or right when driving on a straight road - Crooked steering wheel
A steering wheel that doesn’t seem to steer center while driving on a straight road - Uneven tire wear
Alignment issues can cause tires to wear faster on the inner or outer edges - Vibrating steering wheel
This can be especially noticeable at higher speeds - Loose or unstable handling
Vehicles that feel less responsive than previously may have alignment issues - Unusual tire noise
Squealing, rubbing, or other noises may be due to misalignment
If you notice any of these symptoms, make an appointment to have your alignment checked.
Most experts recommend checking your wheel alignment at least once per year or whenever you install new tires.
You should also consider checking your alignment if:
- You hit a large pothole
- You notice uneven tire wear
- The vehicle is pulling to one side
- The steering wheel becomes off-center
How Wheel Alignment Protects Your Tires
Wheel alignment plays a major role in tire wear patterns.
When wheels are misaligned, tires no longer contact the road evenly. This causes certain areas of the tire to wear down faster than others.
Common tire wear patterns caused by misalignment include:
- Edge Wear
Inside or outside edge of the tire wears faster - Feathering
The tread feels smooth in one direction but sharp in another - Cupping
Also called “scalloping,” this pattern creates uneven dips across the tire tread and can cause vibration or road noise
Correct alignment distributes pressure evenly across the tire’s surface, extending tire life and improving performance.
How Wheel Alignment Affects Gas Mileage
Wheel alignment doesn’t just affect tire wear—it also can impact fuel efficiency.
Misaligned wheels create more rolling resistance as they move. This means your engine must work harder to maintain speed. As a result, poor alignment can reduce gas mileage (or range) and increase overall driving costs.
Keeping your wheels properly aligned helps reduce unnecessary resistance and supports better fuel efficiency.
What Causes Wheel Misalignment?
There are a number of potential causes to a wheel misalignment:
- Potholes or road hazards
Potholes, debris, or curbs can knock wheels out of alignment. - Suspension wear
As suspension components age, they can loosen or shift. - Minor accidents
Even small impacts (such as a “fender bender” or bump) can alter wheel angles. - Normal driving conditions
Over time, normal driving can gradually affect alignment due to typical impacts, rough driving surfaces, aging components, and more.
Because these factors are common, most vehicles will need periodic alignment checks to maintain optimal performance.
Alignment Angles Explained: Camber, Caster, and Toe
During your alignment service, technicians adjust several key angles that affect how your wheels and tires contact the road.
Camber
This refers to the inward or outward tilt of the wheel when viewed from the front of the vehicle. Negative camber is a tire tilted inward; positive camber is a tire tilted outward. Too much camber can cause excessive wear on one edge of the tire.
Caster
This refers to the angle of the steering axis when viewed from the side of the vehicle. Proper caster helps maintain stability and steering control. It can be negative, positive, or centered.
Toe
This refers to whether the tires point slightly inward or outward when viewed from above. Your drivetrain (RWD, AWD, for example) has specific requirements for your tire’s toe angle. Incorrect toe angles are one of the most common causes of uneven treadwear.
What Happens During A Wheel Alignment Service
A wheel alignment service requires specialized equipment to measure and adjust wheel angles.
During this process, a technician will:
- Place the vehicle on an alignment rack
- Attach sensors to the wheels to measure alignment angles
- Use computerized equipment to compare measurements with manufacturer’s specifications
- Adjust camber, caster, and toe as needed
- Verify final measurements and confirm proper alignment
Many alignment services also provide a before and after report displaying the adjustments made during the service.

Wheel Alignment FAQ
Here are the most common wheel alignment questions we receive:
Wheel alignment adjusts the angles of your vehicle’s wheels so they meet the road correctly. This helps improve steering control, prevent uneven treadwear, and maintain stable handling.
Common signs include your car pulling to one side, a crooked steering wheel, uneven tire wear, vibrations, or loose steering.
Misalignment is commonly caused by hard impacts from potholes, curbs, road hazards, and minor collisions. Suspension or component wear is also a common cause.
Tire cupping (also sometimes called scalloping) is an uneven wear pattern where dips form across the tread. It can cause vibration and road noise and may indicate suspension or alignment issues.
You should get a wheel alignment check once a year, or whenever new tires are installed.
