Tire Sidewall Damage – 2024 It’s Not Just Poor Driving

According to NTSB (National Transportation Safety Board), approximately thirty-three thousand tire-related accidents happen yearly, out of which two thousand are related to tire sidewall damage. Tire sidewall damage can be thought to be minimal at first glance, but with proper diagnosis, you may discover a more significant fault with your tires.

Complete replacement of your tires can be costly, especially if you have giant rims, hence the need to consider if repair is possible. Read on to know more about tire sidewall damage; what causes it? Can it be repaired? Can one tire be replaced? Is it safe to drive with sidewall damage and top tire brands you can buy for your car?

Tire Sidewall Damage [Quick Overview]

Tire sidewall damage can occur when the sidewall of the tire is punctured, cut, or otherwise damaged. This type of damage can cause a tire to leak air or potentially fail, leading to a loss of control of the vehicle.

What is Tire Sidewall Damage?

What is Tire Sidewall Damage?

Simply put, tire sidewall damage is damage to your tire’s sidewall; this means that the damage is not directly on the treaded part of your tire but its sides. Most times, tire sidewall damage is not repairable.

The tire side is the part that extends from the shoulder area to the point the tire touches the rim. It is the part of the tire where you can see the effect of the pressure felt by the tire as a result of the load or contact with the road surface.

This part of the tire is large and soft, making it susceptible to wear and tear. All noticeable deficiencies and issues around your tire sidewall are classified as tire sidewall damage. Sometimes, it is in the form of a bubble or deep scratch on the tire side.

Some noticeable signs of this damage are swelling, cracking, loss of rigidity, a puncture or missing chunk of rubber, vast and deep abrasions from hitting curbs, a bulge, and many more. These damages sometimes result from an accident or result of poor driving experience.

In addition, any missing chunk in your tire or abrasion will expose the textile cords within, and this could lead to a bigger problem. This is why we will consider if it is safe to drive your car with its tire sidewall damage.

Driving on a Tire With Sidewall Damage – Is It Safe?

Driving on a tire with sidewall damage is not safe, except you are on that trip to get it fixed. Unfortunately, many car owners assume they can use such tires without repairing or replacing them. So instead of risking your life, why not improve the damaged sidewall as a temporary solution.

If you drive with sidewall damage on your tire, you risk a blowout which could be dangerous at high speeds; even if you do not experience a blowout, your driving experience will be roughly coupled with bad fuel management.

In addition, your sidewall is more sensitive than the treaded part of your tire, and so, they can lead to an immediate failure of your MOT. Besides, it is considered illegal when you drive with a sidewall that has been damaged severely. It attracts a fine of up to $2,500 for each tire and point deductions on your license.

How Much is Too Much – Tire Sidewall Damage

Now you know that driving with tire sidewall damage is not safe for you, but the truth is, sometimes your pocket cannot accommodate the expenses for an immediate repair or replacement. Hence, the question is, how much tire sidewall damage is too much?

When the repair or replacement is imminent, what is the limit of managing your car’s tire sidewall damage? Even though you can manage the sidewall damage to your car, it still comes as a second option because you cannot risk your life in place of saving costs. Your life is costlier!

Since any minor issue in your car can become something massive over time, you should go for a repair or replacement at any slight indication. For example, whenever you see your tire treads dangling, you need not drive that tire for a second more.

This is the limit to using it before experiencing a blowout. Tire treads are located between 3mm to 4.5mm (1/8″ to 3/16″) into your tire; seeing them sometimes is not a guarantee of a blowout. A further check that reveals noticeable bubbles on the tire sidewall indicates an immediate replacement of the whole tire.

No products found.

This means that the air trapped inside your No products found. is about to escape; it is advisable to locate an expert to look at your tire immediately to avoid the risk of a blowout at any moment. In addition, you can identify workshops specializing in repairs and not tire sales to get an honest review of your tire sidewall.

Can Sidewall Tire Damage be Repaired?

In general, according to Rubber Manufacturers Association, about 88% of all tire-related repairs are not done correctly. Of course, this is because many repair shops and mechanic workshops are not adhering to industry guidelines about tire repair.

Regarding tire damage, though you can fill the holes in the tire (punctures), you cannot do the same for tire sidewall damage. This is because a puncture does not affect the overall structure of your tire. However, tire sidewall damage does. So while a puncture is repairable, trapped air in the tire cannot be fixed, except if you want to destroy the tire the more.

deep gluing as long as it does not get to the treads

Another case of unrepairable sidewall damages is those that reach the treaded regions. This is because it affects the overall tire structure. Damages like shallow scratches on the sidewall can be fixed by deep gluing as long as it does not get to the treads. However, if the scratch is indeed shallow, it needs no fixing.

In summary, tire sidewall damage is unrepairable if it goes past the tread, but if not, it is seen as a minor damage. Therefore, rather than risking one’s life in driving a car with tire sidewall damage, it is safe to replace the tire and avoid the risk of a blowout for a long time.

Main Causes of a Tire Sidewall Damage

Let us look at the significant causes of tire sidewall damage; knowing them can help you lengthen the lifespan of your tire if you avoid them. Some of the numerous causes of tire sidewall damage are:

  • Under inflation
  • Damage
  • Overload
  • Age
  • Tire wear
  • Manufacturing defects
  • Vandalism
  • Poor Driving

Under inflation

Your car tire loses air at a rate of 2psi per month and about 1psi for every 10°F temperature drop. Therefore, when your car is under-inflated due to the negligence of the car owner, it can become a big issue because the load in the car will outweigh the pressure, hence leading to a damaged sidewall.

When there is not enough pressure in the car tire, buildup around the sidewall will occur faster, and the sidewall will flex to hold up the load in the vehicle. This can put your car in immediate danger of a blowout.


Damage can result from a poor driving experience and various road hazards. Improper installation and maintenance of your tire can also lead to tire sidewall damage. This makes the tire lose air fast, and blowout becomes inevitable.

It is advisable to check your tire treads and sidewall during your routine maintenance to ascertain their state. If you do not know what to look for, you can ask your mechanic to incorporate it as your regular check during your scheduled monthly maintenance.


Most multipurpose and commercial vehicles face the problem of overloading, and they end up with tire sidewall damage most times; when your car handles too much load than it should, the wheels bulge or wiggle while in motion.

The tire becomes less stable and is prone to the explosion -blowout. In addition, whenever you notice your sidewalls coming in contact with the road, you are prone to sidewall damage because only the treaded part of your vehicle should contact the road directly.

In summary, because your sidewall is soft, it is made of different materials compared to your tire’s treaded part. Hence, any direct contact with the road surface contributes to its deterioration.


The average service life of a tire ranges from 6 to 10 years, depending on the brand or manufacturer. When a tire is past its average service life, it begins to degenerate due to continuous exposure to heat and oxygen. Some of the signs of an old tire are noticeable wear due to prolonged usage.

The tire then loses its flexibility and becomes very hard and brittle. Inner pile connections weaken, and vulnerability increases. In addition, it loses the ability to withstand heat and the chances of a tire sidewall explosion increase.

Tire wear

Our focus here is bald tires. Do you know that driving bald tires accumulate heat faster than those with proper tread? A tire is first bald before it shows its cords and then calls for total replacement. Driving a bald tire and mistakenly hitting a curb can cause quick air loss and, eventually, a blowout.

The standard legal tread depth is 2/32” in many states; however, if your tire depth reaches or exceeds 4/32″, the chances of a sidewall blowout, especially when you hit a small pothole, is inevitable.

Manufacturing defects

Some causes of sidewall effects are beyond you; one of them is the manufacturer’s defect. This is why you should look at our recommended tires that have been tried and tested. A low-speed rating can cause tire sidewall damage and compromise your overall safety as a driver.

If there are any manufacturing defects, your tires can overheat after installation and sometimes wear faster than expected. It would be best if you only bought from trusted and recommended brands to avoid having a bad tire prone to sidewall damage.


This is another cause of tire sidewall damage when someone intentionally cripples your car to attack you or settle mischief. In such cases, until you have the tire replaced or repaired, you cannot continue your journey.

Poor Driving

Reckless driving can lead to tire sidewall damage; imagine driving and hitting a curb when there is an option to maneuver without crashing it. Over time, it affects your tire walls till they become so tender and eventually get damaged.

Can I Replace Just One Tire?

Replacing just one tire comes with many considerations; you must consider these considerations before replacing just one tire. Most times, when you are faced with replacing just one tire, it’s a result of a blowout or any other unrepairable situation.

The tread depth is around 10/32″ or 12/32″ for new tires. Now, imagine putting this up with a 4/32″ depth tread on the opposite side. Hence, the safest thing to do is replace both tires; keep the following in mind when replacing just one tire.

Type of tire

Your tires should have the same or similar tread patterns, and this can only come from buying the same model. This is a significant consideration if you want a predictable and balanced driving experience. Subtle differences in your tires affect their response to the vehicle’s ability to brake, corner, accelerate or handle water.

go for another all-season tire

If the exact tire model is not available, go for a similar option. For example, go for another all-season tire if the previous one has gone bad, and do not get an asymmetric tread pattern when the damaged tire has a directional tread pattern.

Type of vehicle

The type of car you drive also determines if you have the option of replacing just one tire. For example, an all-wheel-drive (AWD) demands the replacement of all four tires at once, as recommended by their manufacturers in conjunction with TIA (Tire Industry Association).

This is because lower tread tires have a smaller diameter and spin faster than the new replacement. As a result, it leads to additional strain on the engine of the AWD vehicle. A slight variation of more than 2/32″ will call for either two or four tires replacement.

While some vehicle manufacturers recommend four-tire replacement at once, some agree to replace just two at once. This is because slightly mismatched tires can lead to costly damage to the AWD vehicle’s drivetrain, transmission, and transfer case.

Tread on other tires

If you will replace tires without affecting the safety and performance, you must note the tread on other tires. If other tires are new, you may have no issues, but worn-out tires with about 4/32″ difference to the recent one call for a complete replacement of both the old and new.
