Driving a heavy-duty truck with misaligned wheels can lead to more than just discomfort; it creates safety risks, poor fuel efficiency, and costly repairs. Misalignment can affect handling and increase wear on critical components, leading to a range of problems that can compromise both performance and safety. As a heavy-duty truck operator, understanding the signs of wheel misalignment is crucial. This article explores the key indicators that your truck needs alignment and discusses the associated maintenance costs, all while emphasizing the importance of regular checks.

Importance of Wheel Alignment

Wheel alignment for heavy-duty trucks, including popular models like Kenworth, Peterbilt, and Volvo, involves adjusting the angles of the wheels according to the manufacturer’s specifications. Proper alignment is essential for several reasons:

Handling: Misaligned wheels can lead to poor handling, making it difficult to steer and control the vehicle, especially in emergency situations. This can be particularly dangerous given the size and weight of heavy-duty trucks.
Tire Wear: Incorrect alignment causes uneven tire wear, which can lead to premature tire replacement. Properly aligned wheels ensure that your tires wear evenly, extending their lifespan and reducing overall costs.
Fuel Efficiency: Misalignment can create additional rolling resistance, which forces your engine to work harder, thereby reducing fuel efficiency. Proper alignment helps achieve optimal fuel economy, which is crucial for the profitability of your trucking operation. According to the Federal Motor Carrier Safety Administration (FMCSA), misalignment can reduce fuel efficiency by 2–3% due to increased rolling resistance.
The ATA Technology & Maintenance Council (TMC) reports that proper alignment can save fleets more than $1,000 per truck per year in combined tire and fuel expenses.

Key Signs of Misalignment

Recognizing the signs of wheel misalignment early can save you from costly repairs down the road. Here are the key indicators to watch for:

Uneven Tire Wear: Check for signs of uneven tread wear. If one side of the tire appears worn more than the other, this indicates an alignment issue. Look out for bald patches, cupping, or feathering on the tread. According to Bridgestone’s commercial tire division, irregular wear patterns like these can shorten steer tire life by 20–50% depending on the severity. Michelin’s truck tire technical guide also notes that feather wear and diagonal wear are among the earliest warning signs of misalignment and suspension issues.
Pulling to One Side: If your truck consistently drifts or pulls to one side while driving straight, it may need alignment. This can make long drives uncomfortable and may affect safety by risking loss of control.
Vibrating Steering Wheel: If you notice vibration in the steering wheel, especially at higher speeds, this often signals misalignment. Vibration can also indicate that your tires are unbalanced or damaged.
A steering wheel that sits off-center when driving straight is a common sign of misalignment. You may find yourself continually correcting the wheel just to keep the truck in its lane, which can lead to driver fatigue. Modern trucks also use steering-angle sensors to detect the exact position of the wheel, and anytime an off-center wheel is corrected, those sensors typically need to be recalibrated after the alignment. Choosing a shop equipped to handle both the alignment and the sensor calibration is essential, which is why drivers rely on The Service Company to do it correctly.
Squealing Tires: If you hear a squealing noise while turning, it may point to misaligned wheels. This noise occurs because the tires are straining to grip the road, causing excessive friction.

Common Tire Wear Patterns and What They Indicate

Irregular tire wear is one of the most reliable indicators of alignment, suspension, or mechanical issues on heavy-duty trucks. Understanding these patterns allows operators and maintenance teams to diagnose problems early and prevent unnecessary downtime and expense.

One-Sided Wear

Appearance: Tread wear concentrated heavily on one shoulder of the tire.
Likely Cause: Camber misalignment, toe misalignment, or axles that are not running parallel.
Professional Insight: Bridgestone identifies one-sided wear as the most frequent alignment-related pattern in commercial steer tires, often signaling the need for a full alignment and suspension evaluation.

Shoulder Step Wear

Appearance: Noticeable high and low spots on either the inner or outer shoulder rib.
Likely Cause: Common on slow-wearing radial tires, and may be influenced by load distribution or minor structural inconsistencies.
Professional Insight: While sometimes cosmetic, it can indicate developing shock or bushing wear if it progresses.

River (Erosion) Wear

Appearance: Channel-like troughs along the edges of the tread ribs.
Likely Cause: Typically found on free-rolling radial tires in steer or trailer positions, often related to slight toe conditions.
Professional Insight: Early detection allows operators to rotate tires before wear accelerates

Feather Wear

Appearance: Tread blocks feel sharp on one side and smooth on the other when you run your hand across the tire.
Likely Cause: Excessive toe settings or thrust-angle compensation from the drive axles.
Professional Insight: Michelin lists feather wear as one of the strongest early warning signs of toe-related misalignment.

Diagonal Wear

Appearance: Diagonal wear patches that repeat around the circumference of the tire.
Likely Cause: Radial run out, misalignment, imbalance, or worn steering components.
Professional Insight: When found on steer tires, it typically points toward a combination of mechanical and alignment faults.

Depression Wear (Center or Shoulder)

Appearance: Localized concave recesses that appear either in the center ribs or along the shoulders.
Likely Cause: Chronic underinflation or overinflation, worn shocks, loose wheel bearings, or mounting irregularities.
Professional Insight: Depression wear is often tied to maintenance practices and can be corrected before significant tread is lost.
