When it comes to maintaining a vehicle, one of the most important components to keep in check is the tires. Tires provide the vehicle with traction, stability, and support. However, tires can become damaged over time due to various reasons, such as uneven wear, punctures, and impact damage. One of the most common types of tire damage is sidewall damage. This damage can be caused by hitting a curb, driving over a pothole, or even by improper inflation. 

In this article, we will discuss how much sidewall tire damage is too much. We will also highlight what actions you can take to address this type of damage.


Explanation of Sidewall Damage

Sidewall damage refers to any harm that happens to the outer wall of a tire. This is the area that sits in the middle of the tread and rim of the wheel. The sidewall is responsible for reinforcing the mass of the automobile and protecting the inner tire from damage. 

Various factors can cause sidewall damage, such as punctures, cuts, bulges, impact damage, weathering, abrasion, and chemical exposure. This kind of damage can weaken the sidewall and increase the risk of a blowout, which can compromise the vehicle’s safety. It is important to regularly check the tires for any signs of sidewall damage and to replace them if necessary.

Types of Sidewall Damage 

Several types of sidewall damage can occur on a tire. These include


These are small holes in the sidewall caused by nails, screws, or other sharp objects. Punctures can be repaired if they are smaller than a quarter inch in diameter and located in the tread area. However, if the puncture is in the sidewall or larger than a quarter inch, the tire should be replaced. 


These are long, narrow slits in the sidewall caused by sharp objects or road debris. Cuts can weaken the sidewall and make the tire susceptible to a blowout. If a cut is longer than a quarter inch, you should replace your tire.


These are raised areas on the sidewall caused by internal damage. Bulges can indicate that the tire is no longer structurally sound, and a new tire should be installed.

Impact Damage

This type of damage is caused by hitting a pothole or curb. It can cause a bulge or a tear in the sidewall, which might lead to a blowout. In case the sidewall appears visually damaged, you must replace it immediately.


Weathering is the process of the tire sidewall being exposed to the elements, such as sunlight, heat, and cold. It can cause cracking or dry rot and should be catered to as soon as possible.


Abrasion is when the sidewall of the tire is worn down due to friction. This can be caused by driving in rough terrain or over debris on the road. If you live in mountainous regions, checking for abrasions regularly is a must.

Chemical Damage

Chemical damage can occur when the tire comes in contact with certain chemicals, such as gasoline, oil, or acidic substances. Chemical damage is not hard to detect, so getting your tires checked once in a while is better. 

Causes of Sidewall Tire Damage 

Sidewall tire damage is not uncommon. However, you must understand its causes. These include

You should also note that any damage that is found on the sidewall of a tire should be considered severe. Regardless of the size or location of the damage, it is best to replace the tire. Failure to do so can compromise the tire’s structural integrity and increase the risk of a tire failure.

When to Replace a Tire 

The lifespan of a tire is determined by several factors. These entail the type of tire, the driving conditions, and the maintenance of the tire. However, even with proper care and maintenance, tires will eventually need to be replaced. 

Sidewall Damage

One of the most common reasons for tire replacement is sidewall damage. Sidewall damage, including cuts, punctures, bulges, or scrapes, is not repairable, and the tire should be replaced immediately. It is unsafe to drive on a tire with sidewall damage, as it often results in tire failure. 

Life Expectancy of The Tire

Tires have a lifespan of around 5-10 years, depending on the type of tire and the usage. Therefore, it is necessary to check the manufacture date of the tire. You can find it on the tire’s sidewall and replace it if it is older than the recommended lifespan. 

Wear and Tear 

Tires worn down to the tread wear indicator are no longer safe to drive on and must be replaced. If the tread depth is less than 2/32 of an inch, it is time to replace the tire. 

Shaking Vehicle

If a vehicle shakes while driving at high speeds, it could be caused by uneven tire wear and calls for a replacement. 

Blistering or Bubbling

Blistering or bubbling on the sidewall of a tire is a sign of internal damage, and the tire should be discarded and replaced.

Potential Consequences of Driving on Damaged Tires
