9 Causes of Bubbles in Tires

A very crucial factor that contributes to tire damage over time is tire bubbles. These bubbles typically grow in size, and because of the increasing pressure on the roads, they eventually burst open and cause accidents. It is essential to know how to avoid situations like this.

Causes of bubbles in tires

To begin with, how did a bubble form? Tires are made up of numerous layers of ply and rubber at a fundamental level. Glue holds the rubber to the plies and provides the tire’s structural rigidity and strength.

Multiple factors contribute to the formation of bubbles, including:

1. Separation of tire layers

A tire obtains its shape when many polyester strands called plies are joined with rubber and steel wires beds using an adhesive. If these layers separate from the tire’s sidewall, the tire begins to bubble.

A variety of circumstances can cause the separation of these layers. Poor manufacturing is one of them. The layers of the tire begin to come out when they are not sufficiently hardened.

Bubbles can also occur if the adhesive used to secure the ply layers, steel wires, and rubber beds become contaminated.

2. Poorly inflated tires

Tires that are poorly inflated have a significant risk of bubbling. If tires aren’t correctly filled, they generate a lot of heat. As a result, the intermediate bonding glue breaks down, allowing bubbles to form.

3. Overburdening of tires

Another factor that can cause bubbles in your tires is routinely putting too much weight on them. Overloading occurs when you load your vehicle to the point that the weight of the cargo exceeds the load capacity of your tires.

While most tires can sustain short-term overloading, few can withstand this amount of force for an extended length of time. Because of the pressure, the tires will begin to spring a leak, allowing air to get trapped beneath the rubber casing.

As a result, you should constantly stick to the tire’s capacity specifications. Unfortunately, there’s no way to patch a bubble in your car’s tires without replacing them.

4. Bad roads

The layers of the tire begin to split when the plies of the tire are broken due to vigorously hitting potholes, speed bumps, or other road debris.

These mishaps cause the layers of the tire to separate. Most drivers travelling through unfamiliar roads approach these potholes and speed bumps. Regular contact with these speed bumps and potholes results in tire bubbles.

Ensure you check out your tires whenever you find yourself driving through the wrong road. 

5. Going on a drive with a flat tire

Flat tires can happen at the most inconvenient moments. Some drivers prioritize fixing flat tires by taking them to the nearest auto shop and having them vulcanized.

On the other hand, others drive their vehicle to their chosen location regardless of the tire’s condition, promising to have it repaired later if the tire does not rapidly lose substantial quantities of air.

Driving with a flat tire allows the tire to come into contact with foreign objects, causing the tire to be forced against the rim, weakening the internal liner, and forcing air leakage into the tire’s body, finally leading to the formation of bubbles.

6. Error in the manufacturing process

Not all tire bubbles are caused by impact or collision; in rare cases, bubbles can form due to internal tire faults, which the tire’s manufacturer typically causes. Depending on your warranty and their policies, You may return it to them in this instance.

7. Worn Out Tire Cover

When a tire’s rubber coating wears down, it is more likely to fracture when it is hit. It indicates that the metal skeleton of the tire is likely to dislocate. When the metal skeleton of the tire dislocates, the result is bubbling.

8. Railway crossing

Motorists occasionally travel on roadways that have railway tracks running through them. If a driver drives the “railway” path daily, such as on his way to and from work, his car’s tires will develop bumps, which will eventually grow into bubbles.

9. Collision with a Curb

Bumping into curbs, however brief and unintentional they may be, can degrade your tires and cause bubbles. Curbs provide a lot of resistance to a tire when it hits them, causing the rubber to collapse in on itself.

These occurrences can cause significant damage to the internal components of your tires and allow air to escape into the casing at high speeds and with repeated instances.

As a result, it’s critical that you avoid making too tight a turn or drifting too far to the side of the road.

Can I drive with a bubble in my tire?

It is hazardous to drive on tires that have bubbles in them. As a result of this bubble, your tire fabric gradually loses its ability to protect your tires from bursts caused by contact with sharp objects on the roads.

The sidewall is the most likely spot to find a bubble in a tire. When the rubber wears very thin, tire bubbles might also occur. Driving on a tire with a bubble is pretty risky, as it is highly likely to blow out on you.

Getting the tire replaced immediately is the best course of action because the bubbles will get bigger as more moisture and air penetrates the tire.

How Long Can I Drive On A Tire With A Bubble?

This problem is long-term and poses no immediate threat. You can forestall further problems by avoiding overspeeding, overloading the car, and sudden acceleration and breaking.

Most importantly, keep in mind that you should avoid physical harm of any sort on the tire. If you’re very careful, you might be able to get a few miles out of the tire. If the tire bubble is rapidly expanding, it’s advisable to stop using the tire.

How do I fix a bubble in my tire?

You cannot mend a tire with a bubble. When bubbles emerge in a tire’s layers, you can’t repair them because they’re already damaged.

Tires with bubbles cannot be mended, unlike flat tires. When a bubble or a bulge occurs on the sidewall, you can’t fix it since the patch would be unable to hold on to anything because the sidewall does not have cord reinforcements like the other layers.

Replacement of the tire with a spare is the only option if you notice bubbles in your tires while driving. Afterward, travel to a repair shop and get the damaged tire changed right away.

Contact the tire manufacturer or the retailer where you purchased your tires to enquire about warranties.


As a precautionary measure, always inspect your tires to make sure that they are correctly inflated. There’s no reason to start panicking if you discover a sidewall bubble in your tires.

Instead, take the tires to a mechanic shop and get them fixed as soon as possible. Do not try to drive the car for a more extended period until the issue has been addressed.
