Run flat tires can develop bubbles in the sidewall due to impact damage. This typically happens when hitting a pothole or curb, which can rupture the inner liner. A bubble signals that the tire’s integrity is compromised and may cause air leakage, similar to problems seen with regular tires.
Over-inflation can also lead to bubbles in run flat tires. When a tire is overfilled with air, the pressure forces the rubber to stretch beyond its limits, resulting in bulges. Additionally, external factors like heat can exacerbate these issues. Heat can weaken the tire material and increase the likelihood of bubbles.
Solutions for dealing with bubbles in run flat tires include regular inspections and monitoring tire pressure. If a bulge appears, it is advisable to replace the tire as soon as possible. Continuing to drive on a compromised tire can lead to blowouts. In the following section, we will explore preventive measures and maintenance tips to extend the lifespan of run flat tires.
What Causes Bubbles to Form in Run Flat Tires?
Bubbles in run-flat tires typically form due to structural damage or manufacturing defects. These bubbles, also known as sidewall bulges, can compromise the tire’s integrity and performance.
- Structural Damage
- Manufacturing Defects
- Improper Inflation
- Heat Damage
- Contaminants in Tire
Understanding these points can help identify the root causes of the bubbles and guide preventative measures.
-
Structural Damage:
Structural damage in run-flat tires occurs when they encounter sharp objects, potholes, or harsh road conditions. When a tire is punctured, the air pressure can cause the sidewall to flex excessively. This flexing leads to the formation of a bubble in the tire surface, which is a sign of internal damage. According to a study by the Rubber Manufacturers Association (RMA), nearly 30% of tire failures result from road hazards causing structural damage. -
Manufacturing Defects:
Manufacturing defects can also lead to bubble formation. These defects might arise from improper curing of the rubber or the use of substandard materials. When tires are not produced following stringent quality control measures, weak spots may develop. The National Highway Traffic Safety Administration (NHTSA) reports that around 5% of tires sold in the U.S. have manufacturing defects, which can lead to unforeseen failures. -
Improper Inflation:
Improper inflation is another leading cause of bubbles. Over-inflated tires can create uneven pressure distribution. This unevenness can force the tire’s sidewall to stretch beyond its limits, resulting in bulges. The Tire Industry Association (TIA) suggests checking tire pressure monthly to avoid such risks. -
Heat Damage:
Heat damage is critical in tire performance. Run-flat tires are designed to withstand heat despite losing air pressure; however, excessive heat caused by prolonged driving with low inflation can weaken the sidewall. A study by Tire Rack indicated that tires run under-inflated for prolonged periods can increase temperatures by as much as 20%, leading to potential sidewall bubbles or failure. -
Contaminants in Tire:
Contaminants inside the tire, such as moisture or debris, can also contribute to bubble formation. Moisture can lead to corrosion of the tire’s internal components, which can cause blistering or bubbles. Experts emphasize the importance of keeping tires clean and free from harmful contaminants to maintain their structural integrity.
By understanding these factors, drivers can take appropriate steps to minimize the likelihood of bubbles forming in their run-flat tires. Regular maintenance and attentive monitoring of tire conditions are essential for ensuring safety and performance.

Road hazards can contribute to bubbles in run-flat tires primarily by causing damage to the sidewalls and internal structure of the tires. This damage can lead to air or gas escaping, resulting in visible bubbles or bulges on the tire surface.
-
Sidewall Damage: Run-flat tires have reinforced sidewalls that allow them to support the vehicle’s weight even when deflated. Road hazards, such as potholes or sharp objects, can compress or puncture the sidewalls. When this occurs, the structural integrity of the sidewall is compromised. According to the Tire Industry Association (TIA, 2022), sidewall damage is one of the most common issues leading to tire failure, especially in run-flat designs.
-
Air Migration: When the sidewalls of a run-flat tire are damaged, air or gas can migrate through the compromised area. This migration can create bubbles or bulges visible on the exterior of the tire. The Organization for Economic Co-operation and Development (OECD, 2021) noted that a significant percentage of bubble occurrences in tires are linked to air leaking from structural damage.
-
Heat Build-Up: Road hazards can also cause heat build-up in tires. Damage to the sidewall or internal structure can create friction, thus generating excessive heat. Run-flat tires are designed to withstand heat better than regular tires, but prolonged exposure to high temperatures can still lead to degradation of the tire material. A study by the National Highway Traffic Safety Administration (NHTSA, 2020) showed that high heat levels can exacerbate tire wear and contribute to internal structural failure.
-
Material Fatigue: Run-flat tires are constructed using specific materials that are more rigid than those in standard tires. When these tires encounter road hazards, the stress can lead to material fatigue. This fatigue can sometimes develop into bubbles as the material weakens over time. Research by the Rubber Manufacturers Association (RMA, 2019) indicated that repeated flexing from road impacts increases fatigue in tire materials, which can lead to deformities like bubbles.
In summary, bubbles in run-flat tires can result from a combination of sidewall damage, air migration, heat build-up, and material fatigue, all of which can be exacerbated by encountering road hazards. Proper tire maintenance and regular inspections can help identify potential issues before they lead to significant tire problems.

Why Are Sidewall Bulges Dangerous for Run Flat Tires?
Sidewall bulges in run-flat tires are dangerous because they indicate structural damage, which can lead to tire failure. These bulges compromise the tire’s integrity and performance, increasing the risk of blowouts while driving.
According to the Tire Industry Association, a reputable organization dedicated to promoting safe tire practices, a sidewall bulge typically signifies that the tire has been impacted, resulting in damage not visible on the outer layer.
The primary cause of sidewall bulges is the impact from road hazards, such as potholes, curbs, or debris. When a tire strikes a hard object, it transfers force to the sidewall. This can lead to the separation of the tire’s internal components, causing air to leak into the sidewall and create a bulge. Other factors, such as overloading the tire or under-inflation, can also contribute to this issue.
In tire terminology, a “sidewall” refers to the side section of the tire that connects the tread to the bead. The “tread” is the part of the tire that makes contact with the road. A bulge indicates that the tire’s structural layers, including the fabric and rubber, are damaged. This could affect the tire’s ability to maintain pressure and grip, creating a dangerous driving situation.
When a sidewall bulge forms, it can alter the tire’s behavior on the road. As the bulged area increases in size, it can lead to uneven wear, poor handling, and loss of control. For example, if a bulge goes unnoticed, it may rupture while driving, potentially causing an accident. Additionally, run-flat tires are designed to support the vehicle’s weight even when they are deflated. However, a bulge undermines this feature by weakening the tire’s sidewall.
Specific conditions that contribute to the formation of sidewall bulges include driving on rough terrain, hitting tall curbs at high speeds, or operating a vehicle with improperly inflated tires. For instance, many drivers experience bulges when they incorrectly inflate their tires based on seasonal temperature changes. Proper tire maintenance and regular inspections can help prevent these dangerous issues.
