Potholes are more than an inconvenience on the road. Hitting a deep pothole can put significant stress on your vehicle’s tires, wheels, suspension, steering, and alignment. Even one hard impact can change the way your vehicle handles.
You may not notice an alignment problem immediately. However, symptoms such as pulling to one side, an off-center steering wheel, or uneven tire wear can develop after the impact.
What Happens When You Hit a Pothole?
Your suspension is designed to absorb bumps and impacts, but a deep pothole can create significant forces throughout the vehicle.
When a tire drops into a pothole and hits the edge on the way out, the impact can affect several components at once. Depending on the severity, you could experience:
- Changes to your wheel alignment
- Bent or damaged wheels
- Tire damage
- Suspension damage
- Steering problems
- Uneven tire wear
Some damage is immediately noticeable, while other problems may not become apparent until your vehicle starts handling differently.
How Can a Pothole Affect Wheel Alignment?
Wheel alignment refers to the angles of your wheels in relation to each other and the road. These angles are set to provide proper handling, stability, and tire contact.
A hard pothole impact can change these angles, even when there is no obvious damage.
Camber
Camber is the inward or outward angle of a wheel when viewed from the front. If a pothole changes the camber angle, one edge of the tire may contact the road more heavily than the other, resulting in uneven tire wear.
Toe
Toe describes whether the front edges of your tires point slightly toward or away from one another. Correct toe settings help your vehicle track properly and allow the tires to roll smoothly.
A pothole can change these settings and cause the tires to scrub against the road, increasing tire wear.
Caster
Caster relates to the angle of the steering axis and plays an important role in steering stability and how the steering wheel returns to center.
Signs a Pothole May Have Affected Your Alignment
Not every pothole will cause an alignment problem, but there are several warning signs to watch for after a hard impact.
1. Your Vehicle Pulls to One Side
If your vehicle consistently drifts left or right while you're trying to drive straight, your alignment may have changed. Continuing to drive with an alignment problem can contribute to uneven tire wear.
2. Your Steering Wheel Is Off-Center
Your steering wheel should sit relatively straight when your vehicle is traveling straight. If it suddenly sits at an angle after hitting a pothole, it could indicate an alignment issue.
3. Your Tires Wear Unevenly
Uneven wear, particularly along the inside or outside edges of your tires, can be a sign that your wheels are no longer properly aligned.
4. Your Vehicle Feels Unstable
Changes in steering response, wandering, or a vehicle that no longer feels like it tracks properly can indicate an alignment or suspension problem.
5. You Notice New Vibrations
Vibrations after a pothole impact can have several causes, including a damaged wheel, tire, suspension component, or alignment problem. If a new vibration appears after a significant impact, it's worth having the vehicle inspected.
Can Potholes Affect Truck Alignment?
Potholes can affect trucks just as they can cars, and the consequences can sometimes be more expensive.
Pickup trucks, work trucks, vans, and commercial vehicles often carry heavier loads and accumulate significant mileage. An alignment problem can accelerate tire wear and affect handling over thousands of kilometres.
For vehicles that spend a lot of time on the highway, proper truck alignment is especially important. Catching an alignment issue early can help protect expensive tires and maintain stable handling.
What About Lifted and Custom Vehicles?
Potholes can be particularly important for vehicles with modified suspension systems.
Lifted trucks, lowered cars, and other custom builds may already have alignment angles that differ from factory specifications. A significant impact can alter those settings further.
Aftermarket suspension components, larger tires, modified ride height, and custom steering components can all affect alignment geometry. If you've hit a major pothole in a modified vehicle, a professional vehicle alignment check can determine whether your setup has been affected.
Should You Get an Alignment After Hitting a Pothole?
Not every pothole requires an alignment. If you hit a minor bump and notice no changes in handling, there may be no reason for concern.
However, consider having your vehicle checked if:
- You hit a large or deep pothole
- Your vehicle starts pulling
- Your steering wheel becomes crooked
- You notice uneven tire wear
- Your vehicle feels unstable
- You hear unusual noises
- You notice a new vibration
- You see damage to a wheel or tire
If you're in the area and notice these symptoms, a Lethbridge alignment specialist can check whether your vehicle's alignment has changed and identify any related issues.
Alignment vs. Suspension Damage
A wheel alignment cannot fix a damaged suspension or steering component.
A hard pothole impact can bend or damage components, and attempting to align a vehicle without addressing that damage will not solve the underlying problem. That's why inspecting the vehicle before performing the final alignment is important.
If a component is damaged or worn, it should be repaired before the alignment is completed.
Don't Ignore Pothole Damage
Potholes are an unavoidable part of driving, but their effects don't have to become a long-term problem.
If your vehicle starts handling differently after hitting a pothole, pay attention to the warning signs. A professional car alignment or vehicle alignment check can determine whether your alignment has changed and whether additional issues need attention.
Proper wheel alignment helps your tires contact the road correctly, improves handling, and can extend tire life. Whether you drive a car, SUV, pickup, van, or heavy-duty truck, maintaining proper alignment is an important part of vehicle care.
