• Solutions: Replace worn shock absorbers and have your wheels balanced.

6. Shoulder Wear

• Causes: Underinflation, aggressive cornering, or worn suspension components.
• Solutions: Check and adjust tyre pressure, avoid excessive cornering, and have your suspension checked.

By understanding these common tyre wear patterns and addressing the underlying issues, you can improve your vehicle’s handling, safety, and fuel efficiency. Regularly inspecting your tyres and maintaining proper alignment and tyre pressure are crucial for optimal tyre performance and longevity.

Factors Affecting Tyre Wear

Several factors can influence tyre wear patterns, including:

Tyre Pressure

• Underinflation: This can lead to excessive heat buildup, increased rolling resistance, and premature wear, especially on the outer edges.
• Overinflation: This can reduce the tyre’s contact patch, leading to reduced grip and increased wear in the centre of the tread.

Wheel Alignment

• Incorrect Alignment: Misaligned wheels can cause uneven wear patterns, such as feathering or one-side wear.
• Regular Alignment Checks: Regular wheel alignments can help maintain proper tyre wear and optimize vehicle handling.

Driving Habits

• Aggressive Driving: Hard acceleration, braking, and cornering can accelerate tyre wear.
• Overloading: Carrying excessive weight can stress the tyres and lead to premature wear.

Road Conditions

• Potholes and Road Debris: Impacting potholes or hitting road debris can damage tyres and cause uneven wear.
• Poor Road Surfaces: Rough road surfaces can accelerate tyre wear.

How to Inspect Your tyres

Visual Inspection:

• Check for Uneven Wear: Look for signs of uneven wear, such as excessive wear on the inner or outer edges.
• Inspect for Cuts and Punctures: Look for any cuts, punctures, or embedded objects in the tyre.
• Check for Bulges or Blisters: These can indicate tyre damage and potential failure.

Tread Depth Measurement:

• Use a Tread Depth Gauge: Measure the depth of the tread grooves to determine if they are within safe limits.
• Replace Worn tyres: When the tread depth reaches the wear bar, it’s time to replace the tyres.

By regularly inspecting your tyres and addressing any issues promptly, you can improve your vehicle’s safety, handling, and fuel efficiency.

Tips for Preventing Excessive tyre Wear

Here are some tips to help you prevent excessive tyre wear:

Regular Tyre Rotations

• Even Wear: Rotating your tyres regularly helps distribute wear evenly across all four tyres.
• Recommended Frequency: Rotate your tyres every 5,000-8,000 miles or as recommended by your vehicle’s owner’s manual.

Proper Tyre Pressure

• Check Regularly: Use a tyre pressure gauge to check your tyre pressure at least once a month.
• Maintain Recommended Pressure: Ensure your tyres are inflated to the manufacturer’s recommended pressure.
• Avoid Overinflation and Underinflation: Both can lead to uneven wear and reduced tyre life.

Professional Wheel Alignments

• Regular Alignments: Schedule regular wheel alignments to ensure your vehicle’s wheels are properly aligned.
• Signs of Misalignment: Uneven tyre wear, the vehicle pulling to one side, or a vibrating steering wheel can indicate misalignment.

Smooth Driving Habits

• Avoid Aggressive Driving: Excessive acceleration, braking, and cornering can accelerate tyre wear.
• Smooth Starts and Stops: Gentle acceleration and braking can help preserve tyre life.
• Avoid Potholes and Road Hazards: Hitting potholes or curbs can damage tyres and lead to uneven wear.

FAQs
