How to Check Tire Sidewall Damage

Tire Sidewall Damage

To ensure safe driving, checking your tire sidewalls regularly is a must. Damage to the sidewall can compromise the tire’s integrity and lead to blowouts or other dangerous situations on the road. While it might seem small, preventing damage early on can help save you from costly repairs. Here are some tips on how to check.

Inspect the entire sidewall of each tire carefully. Look for any cuts, punctures, bulges or other signs of damage. These can indicate a problem with the tire’s internal structure and may require immediate attention.

Pay attention to any cracks or irregular wear patterns on the sidewalls. These could be caused by overloading or underinflation and may lead to blowouts or other dangerous situations while driving.

Check your tires regularly, at least once a month, especially before long trips or extreme weather conditions. It’s best to have your tires professionally inspected by a qualified mechanic.

What Causes Tire Sidewall Damage

Tire Sidewall Damage

This is a common problem faced by many drivers. The most apparent cause of such damage is running over sharp objects such as nails, broken glass, and rocks. Several factors can contribute to this.


When tires are not correctly inflated, they become more susceptible to wear and tear, leading to sidewall damage. Under-inflated tires make it harder for a vehicle to handle correctly on the road. This adds strain to your tires as they must work harder than necessary while driving, especially when making turns or stopping suddenly. Over time this added pressure can cause cracks or tears along the tire’s sidewall, which can be expensive and dangerous if not addressed immediately.


Overloading your vehicle with too much weight can put undue stress on your tires and cause them to wear out prematurely. When you exceed the maximum weight capacity that your tires can handle, it puts a lot of stress on your tires’ sidewalls. Your tire’s sidewall is responsible for holding up your car’s weight and providing stability, so when it becomes damaged due to overloading, it can lead to severe problems.

They are also more prone to blowouts and punctures. The added pressure on the sidewalls increases the risk of your tire bursting or getting punctured by road debris.


Over time, tires naturally lose their elasticity and become brittle, which makes them more susceptible to cracks and other forms of damage. This process is accelerated by exposure to UV light from the sun, high temperatures, and frequent use.

As tires age, they also become more prone to blowouts and punctures. This is because the rubber begins to break down and weaken over time, reducing its ability to withstand impact or sudden changes in pressure. 

Road Hazards

Road hazards can be anything from sharp objects like nails and glass to potholes or debris on the road. One of the main culprits is potholes. They are formed when water seeps into cracks in the pavement, freezes, and expands, causing a hole to form. Driving over a pothole can cause severe damage to your tires’ sidewalls and other parts of your car’s suspension system.

Debris on the road can also be a cause. Objects such as rocks or broken glass can puncture your tire’s sidewalls if they come into contact with them while driving at high speeds.

Manufacturing Defects

These defects occur during production and can harm the tire’s performance and durability. Manufacturing defects can include issues such as weak spots in the rubber, improper curing or bonding of materials, or faulty design. These defects make tires more sensitive to punctures, blowouts, and other forms of damage, leading to costly repairs or even accidents on the road. 

In some cases, manufacturers may recall tires due to significant flaws in their production processes that could pose safety risks for drivers.

How Much Tire Sidewall Damage is too much?

Tire Sidewall Damage

It can be a common issue for drivers, and it’s essential to know when the damage is severe enough to require immediate action. They are an essential component that provides structural support to the tire and allows for safe operation on the road. When the sidewall of a tire is damaged, it can cause significant issues with performance and safety.

Minor sidewall damage, such as small cuts or scrapes, may not immediately threaten your tire’s safety or performance. More significant cuts or punctures in the sidewall can compromise its integrity. Inspecting your tires regularly for any signs of sidewall damage that could affect their overall safety on the road is essential.

As a general rule of thumb, any visible bulge or crack in your tire’s sidewall should prompt an immediate replacement.

Is it Safe to Drive on a Tire With Sidewall Damage?

Tire Sidewall Damage

Driving on a tire with sidewall damage is never safe. The sidewall of a tire helps to maintain the structural integrity of the tire. When damaged, it can weaken the entire tire and increase the likelihood of complete failure while driving. Any damage to the sidewall can lead to a weakened structure, which poses a considerable risk to the driver’s safety.

It can also affect your vehicle’s handling and stability on the road. It increases your risk of experiencing blowouts or punctures that can cause accidents, especially at high speeds. The damage may also cause irregular wear and tear on other parts of your vehicle, such as suspension components.

A professional must inspect your tire immediately if you notice any signs of sidewall damage, such as bulges, cuts, or punctures. 

Can Tire Sidewall Damage be repaired?

Tire Sidewall Damage

Sidewall damage is any cuts, punctures, or cracks on a tire’s side. Unlike tread damage which affects only the surface area of a tire, sidewall damage can compromise its structural integrity and make it unsafe for use. 

Many automakers recommend replacing tires with sidewall damage rather than repairing them as a safety precaution. This is because sidewalls don’t have reinforcements like treads and are more susceptible to blowouts if damaged.

If there is a minor cut or puncture on the outermost layer of rubber, it could be repaired using patches or plugs. If the damage is too severe, repairing may not be an option, and replacing your tire would be necessary.

How to prevent Tire Sidewall Damage

Tire Sidewall Damage

This can be a significant issue that affects the safety and longevity of your vehicle’s tires. The good news is that you can take several steps to prevent this type of damage from occurring. Here are some tips to keep in mind:-

Proper inflation: One of the most effective ways to prevent it is by ensuring that your tires are inflated to the recommended pressure level. Overinflated tires can cause excessive sidewall stress, leading to cracks or bulges.

Avoid potholes and other hazards: When driving on rough roads or over obstacles like curbs or speed bumps, avoid hitting them head-on with your tires. Instead, try to straddle them if possible.

Regular maintenance: It’s essential to have your tires checked regularly by a professional mechanic for signs of wear and tear. Make sure your tires are correctly aligned and balanced.

Drive carefully: Be aware of your surroundings and drive cautiously to avoid running over debris on the road.

Avoid overloading your vehicle: Overloading your vehicle puts extra pressure on your tires, which can cause them to wear out faster and increase the risk of sidewall damage.

Regularly rotate your tires: Rotating your tires every 5,000-7,000 miles ensures that the wear and tear on each tire are evenly distributed. This helps prevent excessive pressure on one sidewall area, which can cause cracking or bulging.


Tire sidewall damage can be a severe issue that should not be ignored. It is essential to regularly inspect your tires for any signs of damage or wear and tear. If you notice any visible cracks, cuts, or bulges on the sidewall of your tire, it is crucial to have them checked by a professional mechanic. Remember, safety should always come first when it comes to driving. Taking proper care of your tires and knowing when to replace them can help ensure a safe and smooth ride. Take your tires today.


How much weight does a tire wear?

The tire’s weight depends on several factors, including the type of vehicle, tire, and how it is used. A tire will wear more quickly for high-speed driving or heavy loads.

What tire damage is acceptable?

Tire damage is subjective and depends on the type of vehicle, driving habits, and the condition of the roads. Minor damage, such as small cuts or punctures, is acceptable as long as they do not affect the overall performance or safety of the vehicle.
