What Causes Bubbles On My Tires? And How To Prevent Them?

A new driver may have no idea what tire bubbles are, yet ignoring them might have serious consequences. If you have tire bubbles, it’s as risky to drive as if you had a flat tire. In certain cases, they can be just as harmful, if not more so.

You may not even notice if your tires have bubbles or bulges, but they can cause accidents and harm your car if they aren’t fixed. Due to air leaks in the tire, these egg-shaped bubbles appear on the side of your tires.

You should repair tire bubbles since they can explode on the road, resulting in a car crash.

What causes tire bubbles? Can I drive with a bubble in my tires? And how can you fix this issue? These are some of the questions answered in this article.

Why Do I Have a Bubble in My Tire? And What Does This Mean?

A tire with a bubble indicates that the tire’s inner layers have been damaged. Your tire is made up of multiple layers. The tire’s air pressure is maintained by the inner layer that is called the inner lining.

Unlike the tire’s outer layers, this layer typically contains no additional reinforcement material, although it is built of a hard rubber that aids in its durability. However, even if it’s built of durable materials, the inner lining has the potential to tear and release air if damaged in any manner.

In the beginning, little quantities of air may escape. But with excessive pressure and other factors, these little air bubbles will grow bigger and more obvious.

Once the inner lining is damaged, the air travels to the outer layers. At a weak region in the tire, like the sidewall, the air gathers and accumulates.

What Causes Bubbles in Tires?

If you see an air bubble in your tire, it indicates that the inner lining has torn and air has leaked out. The bubbles are usually caused by impact damage. When the tire is squeezed between the wheel and the road or a curb, the weak point might inflate.

Driving on poor roads or other external factors that cause impact damage might potentially result in air leakage. These are some of the main causes of bubbles in tires:

Driving over rough roads

Traveling on uneven roads is the leading cause of tire bubbles. Not slowing down on bumps, driving over potholes and jagged road debris are all reasons to have tire bubbles.

Driving with a flat tire

Of course, no one intends to drive for a long period of time with a flat tire. However, flat tires don’t give us any warning signals. If the spare tire is unavailable or the driver just doesn’t know how to change the tire, the driver might have to go to a nearby service provider to fix the tire.

Moreover, if the air leaks aren’t too bad, some drivers may choose to drive down to their preferred mechanic’s shop and get it fixed there.

Regardless of the circumstances, driving with a flat tire is dangerous. This will indeed cause more pressure on the tire’s inner lining, damage it and cause air to be forced to the outside layer.

Hitting the curb

An accidental and rapid hit against the curb may create tire sidewall bubbles. Tires are the only parts of the vehicle that come into direct touch with the road; thus, they take the highest amount of the impact.

If this habit persists, especially at high speeds, the inner lining of the tires will be damaged, allowing the air to leak out to the outside layer. These are some of the reasons that cause tire bubbles, and the list could go on and on. Now let’s find out how this issue could be fixed.

How to Fix a Tire with a Bubble

Unfortunately, there is no way to fix a tire with a bubble in it. When bubbles develop in a tire’s layers, they can’t be repaired because they’ve already been harmed.

Tires with bubbles cannot be fixed, unlike flat tires, which may be repaired. To fix a sidewall bubble, you would need a patch with cord reinforcements, but since the sidewall does not have any cord reinforcements, this is not an option.

If you notice air bubbles in your tire(s), your only option is to change the damaged tire with a spare.

Is It Safe to Drive with Tire Bubbles?

Driving on a damaged tire is never a good idea. However, you may not always have the option to change it immediately. The size of the sidewall bubble also has an effect. Although a tiny sidewall bubble should not be neglected, it is still possible that it will not need the installation of the spare right away.

In addition, driving on a tire with a bubble is safer than getting out of the car in a dangerous neighborhood or on a busy road in a high-traffic area. However, a tire blowout can occur if the air bubble in your tire is kept under tremendous pressure, although this is rare.

If you had to drive a tire with a small bubble, just keep in mind to drive more slowly than usual. Driving at high speeds, in bad weather, or on busy roads, is very risky with a bubble in your tire.

How To Prevent Tire Bubbles Formation

Tire bubbles have been shown to cause injuries, deaths, and crashes. As a result, the wisest course of action is to avoid them at all costs. These are some of the steps you could do to prevent this from happening to your tires.

Avoid Large Potholes and Speed Bumps

One of the most common causes of tire bubbles is driving over potholes and speed bumps. Sidewall bubbles can form on your tires due to the pressure they are put under as you drive over these obstacles, especially if you’re doing so at high speed.

You should also be aware of curbs and other obstacles that might harm your tires while turning or entering the drive-thru.

Don’t Overload Your Car

Carrying too much weight puts greater pressure on the tires. When a vehicle is carrying an excessive amount of weight, the tires may develop bubbles or bulges.

Make sure you don’t constantly have to carry heavy weights around with you. In order to keep tire bubbles at bay, it’s important to stay within your tire’s weight capacity.

Regular Tires Checkups

It’s critical that you inspect your tires before going to work every day. This is especially true if you’re driving on bad roads.

Another benefit of frequently inspecting your car tires is that it can help you spot problems before they become more serious.


The presence of air bubbles in a tire has the potential to cause a serious accident. In order to save money, you should keep an eye out for small problems with your tires and address them before they become major ones. Establish a routine maintenance schedule and stay updated on any problems.

And an important point to keep in mind is that you should always follow your manufacturer’s recommendations and instructions when repairing or replacing any parts.
