Tyre sidewall damage is one of the most common issues drivers face, and it can lead to serious safety concerns if not addressed properly. Sidewall damage affects the outer edges of the tyre and is often caused by impacts with curbs, potholes, or sharp objects on the road.

Unlike surface tread wear, sidewall damage can weaken the structure of the tyre, posing a risk for blowouts. At Mobile Tyre Surgeons, we understand the importance of identifying and preventing sidewall damage to keep you safe on the road.

If you’re in the area and need assistance, our mobile tyre fitting Croydon service is here to help, bringing expert care directly to you.

In this guide, we’ll walk you through the causes of sidewall damage, how to spot it, and the steps you can take to prevent it.

What Is Tyre Sidewall Damage?

The sidewall of a tyre is the part that extends vertically from the edge of the tread to the inner edge near the wheel rim. This area helps support the weight of your vehicle and absorbs shock while driving. However, sidewalls lack the reinforced tread found on the tyre surface, making them more vulnerable to impacts and cuts.

Damage to the sidewall may appear as bubbles, cuts, abrasions, or cracks. Even minor sidewall damage can compromise the structural integrity of your tyres, increasing the risk of a tyre blowout while driving. For these reasons, it’s essential to check your sidewalls regularly for signs of damage and address any issues immediately.

Common Causes of Tyre Sidewall Damage

Understanding what causes sidewall damage can help you avoid it. Here are some common sources of sidewall damage:

1. Curbs and Potholes

• Hitting curbs or potholes is one of the most frequent causes of sidewall damage. The impact can create small cuts or even larger bubbles in the sidewall, weakening the tyre.

2. Sharp Objects on the Road

• Nails, glass, and metal debris on the road can easily puncture or cut the sidewall if you drive over them, leading to immediate or gradual damage.

3. Underinflation

• Driving on underinflated tyres puts extra strain on the sidewalls, making them more prone to cracking or bulging. Regularly checking tyre pressure is an easy way to prevent this issue.

4. Excessive Load

• Carrying heavy loads can strain your tyres, particularly the sidewalls, which bear much of the weight. Overloading your vehicle increases the chance of developing sidewall damage.

5. Sun Exposure and Age

• Exposure to sunlight can degrade the rubber in tyres over time, leading to sidewall cracks. Additionally, tyres naturally age, and older tyres are more susceptible to sidewall damage.

How to Identify Tyre Sidewall Damage

Spotting sidewall damage early can prevent further issues and keep your vehicle safe. Here’s what to look for when inspecting your tyres:

1. Bulges or Bubbles

• A bulge or bubble on the sidewall indicates that the internal structure of the tyre has been compromised, often due to impact with a hard object. This damage is critical and requires immediate replacement of the tyre.

2. Cracks

• Cracks on the sidewall can appear due to age, exposure to UV rays, or driving on underinflated tyres. Small cracks may be manageable in the short term, but extensive cracking calls for replacement.

3. Cuts and Abrasions

• Cuts are typically caused by sharp objects or scraping against rough surfaces. If the cut penetrates deeply, it can weaken the tyre and increase the risk of a blowout.

4. Punctures

• While less common on sidewalls than on treads, punctures can still occur. Unfortunately, sidewall punctures are generally not repairable and may require tyre replacement.

5. Discoloration

• Discoloration on the sidewall can signal deterioration, especially if the tyre is old. While not always indicative of immediate damage, it’s a sign to monitor the tyre’s condition closely.

Prevention Tips to Avoid Tyre Sidewall Damage

To minimize the risk of sidewall damage, follow these preventative steps:

1. Avoid Hitting Curbs and Potholes

• Drive carefully and avoid hitting curbs or potholes whenever possible. Slow down when approaching areas with uneven surfaces to reduce impact on your tyres.

2. Maintain Proper Tyre Pressure

• Underinflation is a common contributor to sidewall damage. Regularly check your tyre pressure and keep it at the manufacturer-recommended levels. This will help distribute weight evenly and reduce stress on the sidewalls.

3. Inspect Tyres Regularly

• Routine tyre checks can catch early signs of sidewall damage. Inspect your tyres visually every month or before long trips, paying special attention to bubbles, cracks, and cuts.

4. Avoid Overloading Your Vehicle

• Check your vehicle’s weight limit and avoid exceeding it. Overloading adds extra stress to the sidewalls, increasing the risk of damage.

5. Rotate Your Tyres

• Regular tyre rotation can help distribute wear evenly across all tyres, including the sidewalls. Rotation every 5,000 to 7,000 miles is generally recommended.

6. Store Tyres Properly

• If you have seasonal tyres, store them in a cool, dry place away from direct sunlight to prevent rubber degradation and sidewall cracks.

7. Use Quality Tyres

• Investing in quality tyres designed for durability can help reduce the chances of sidewall damage. High-quality tyres may cost more initially but tend to last longer and provide better safety.

Why Address Sidewall Damage Immediately?

Sidewall damage, even if it seems minor, can escalate quickly and lead to dangerous situations on the road. A tyre with a weakened sidewall is at risk of a blowout, which can result in loss of control, especially at high speeds. Unfortunately, sidewall damage is not repairable in most cases. Unlike tread punctures, which can sometimes be patched, sidewall repairs compromise the integrity of the tyre, making it unsafe to drive on.
