Why Is There A Bubble In My Tire?

Tire bulges or bubbles occur when the inner lining of the tire of your vehicle becomes damaged. Generally, the inner lining of the tires is responsible for containing air.

When the inner lining of the tire becomes damaged, it becomes weak and springs a leak. If that happens, air seeps through the leak of the inner lining with the pressure from the road, trapped under the outer layer of the tire. 

More air starts collecting over time creating a visible bulging known bubble of the tire. There are several reasons for the damage to the inner lining of the tire.

Let’s check that out. 

#1. Impact Damage

The vast majority of the tire bubbles are caused by the impact damage. When the tire of your vehicle hits a sharp object on the road, the force created from the speed and the weight of the vehicle is centered in a small area. 

It pinched the inside of the tire causing a small hole in the inner lining. As a result, it creates a way for the air to escape.

Some of the most common impact damage are included –

  • Potholes
  • Speed bumps
  • Curbs
  • Railroad crossings
  • Road construction areas
  • Debris in the road
  • Heavily damaged roads

#2. Driving With A Flat Tire

If one drives the vehicle with a flat tire repeatedly, it causes the tire of the vehicle to come in contact with foreign objects. It causes the inner lining of the tire to be damaged, which results in the tire bulging or tire bubbles.

#3. Under-inflated Tires

Under-inflated tires hold a risk of bubbling. When the tires are not inflated properly, it creates excess heat causing adhesive collapses of the adhesive bonding. This creates a way for the tire bubbles.

#4. Overloading

It is one of the main causes for the tires to have a bubble. Overloading of the vehicle damages the steel and plies from the internal of the tires. It caused the failure of the alignment of the tires, showing a bulging.

#5. Manufacturing Defect

Not only impact damage, overloading, or negligence is the reason for the bulging of the tires, but also it can happen due to manufacturing defects.

Although it is likely a very rare case, sometimes the glue fails to hold the layers of the tire together creating gaps for bubbles to form.

Due to the reduced traction, it will be challenging for the drivers to maintain control over the vehicle, especially in unfavorable weather conditions and on busy roads.

#2. Blowout Potentiality

Since more and more air escapes from the inner lining of the bubbled or bulged tire, it possesses the potentiality of unexpected blowouts during driving.

No wonder that can trigger an alarming situation for both yourself and your vehicle as well!

If you have one or more tire bulges, the weight of the vehicle cannot be distributed evenly. When that happens, it causes irregular tire wear. It additionally compromises the safety of yourself on the road.

Do Tire Warranties Cover Bubbles?

You know tire warranties indeed cover the pro-rated replacement or the replacement of the bubbled tire only when the bubble occurs due to the manufacture defects.
