Tire pressure plays a pivotal role in maintaining proper wheel alignment. Incorrect tire pressures, whether over-inflated or under-inflated, can distort the tire’s contact patch with the road, affecting alignment angles and handling.

Managing Tire Pressure

• Regular Checks: Monitor tire pressure monthly and before long trips using reliable gauges.
• Follow Manufacturer Guidelines: Adhere to the recommended tire pressures specified in your vehicle’s manual for correct pressure.
• Balanced Inflation: Ensure all tires are inflated evenly to prevent alignment issues like the vehicle pulling to one side.

5. Improper Installation of Parts

Incorrect installation of suspension or steering components can lead to misalignment. This includes improper torque settings, misaligned parts, or using incompatible components, which disrupt the vehicle’s alignment and can cause bad alignment symptoms.

How to Ensure Proper Installation

• Certified Technicians: Have parts installed by professionals at reputable auto repair shops or service centers.
• Quality Service: Choose auto service and repair centers that use proper installation procedures and quality components.
• Double-Check Work: After installation, ensure that an alignment inspection is performed to verify that everything is correctly aligned.

Symptoms of Poor Wheel Alignment

Uneven tire wear is one of the most apparent signs of misalignment. Tires may show wear patterns like camber wear, where one side of the tread wears faster, or toe wear, which affects the inner or outer edges.

Types of Uneven Wear

• Cupping or Scalloping: Wavy wear patterns across the tread due to worn suspension components.
• Feathering: Smooth on one side and sharp on the other, indicating incorrect toe angle.
• Sidewall Tyre Wear: Excessive wear on the tire’s sidewall due to misaligned wheels.

Action Steps

• Regular Tire Inspections: Check for unwanted wear patterns monthly.
• Professional Assessment: Visit an auto repair professional or tire shop like Firestone Complete Auto Care if uneven wear is detected.

2. Crooked Steering Wheel

If your steering wheel is not centered when driving on a straight road, it is a classic sign of wheel misalignment. The steering wheel angle should align with the vehicle’s intended lane of travel.

Additional Indicators:

• Steering Wheel Vibrations: Vibrations in the steering wheel, especially at higher speeds, can indicate alignment issues or unbalanced wheels.
• Difficulty Steering: The vehicle feels unstable or hard to control, affecting the overall driving experience.

Action Steps:

• Professional Wheel Alignment: Have an alignment service performed to correct the steering alignment.
• Check for Other Issues: Ensure that vibrations are not due to bent rims or other mechanical problems.

3. Vehicle Pulling to One Side

Consistent drifting or pulling to one side while driving indicates misaligned wheels. This issue not only makes driving difficult but also poses safety risks.

Potential Causes:

• Incorrect Toe Angle: Wheels are angled inward or outward rather than parallel.
• Camber Misalignment: Uneven vertical tilt of the wheels, either positive camber or negative camber.

Action Steps:

• Tire Pressure Check: Ensure all tires have the correct air pressure.
• Alignment Correction: Schedule an alignment adjustment to realign the wheels.

Vibrations in the Steering Wheel

Experiencing vibrations in the steering wheel can indicate misalignment or other issues like unbalanced tires or worn suspension components.

Possible Causes:

• Imbalanced Tires: Misalignment causes uneven rotation, leading to vibrations.
