Bulges in tire sidewalls are caused by structural weaknesses and can be dangerous to drive on. These weaknesses can be the result of manufacturing defects, impact damage, or overloading the tire beyond its capacity.
Tires are an essential component of any vehicle. They play a crucial role in ensuring proper handling, stability, and safety while driving. Unfortunately, even with meticulous care and maintenance, tires can develop bulges in their sidewalls. A bulge in a tire sidewall refers to a protrusion on the outer surface of the tire that is caused by a weakness in its structural integrity.
This can be a serious safety concern, as bulges increase the likelihood of tire failure and potentially catastrophic blowouts while driving. In this article, we will explore the causes of tire sidewall bulges and provide useful information on what you should do if you notice this issue with your vehicle’s tires.

Understanding Tire Sidewall Bulge
Tires play a vital role in a vehicle as they provide the necessary support, stability, and traction on the road. However, tire sidewall bulge can be a common issue for some car owners. In this section, we will provide a clear definition of tire sidewall bulge, explain the different bulge types, and provide illustrated examples.
Definition Of Tire Sidewall Bulge
A tire sidewall bulge happens when the tire’s sidewall protrudes out from its normal position. This can occur for various reasons, such as hitting potholes, overloading the vehicle, or driving on damaged roads.
Explanation Of Different Types Of Bulges
There are several types of tire sidewall bulges, and it’s crucial to be aware of them to understand the cause and severity of the problem. Here are the most common bulge types and their characteristics:
- Belt separation bulge: This bulge type appears due to the separation of the tire’s internal belts. The bulge is usually wider and flatter than the other types.
- Impact bulge: As the name suggests, this bulge type occurs due to the impact of hitting potholes and curbs. The bulge is small, round, and often found at the tire’s edge.
- Overloading bulge: When a vehicle carries more weight than the tire can handle, this bulge type can occur. The bulge will be small, and it will be hard to notice unless the weight limit is substantially exceeded.
- Manufacturing defect bulge: In rare cases, a tire may have a bulge due to a defect in the manufacturing process. This type of bulge is hard to differentiate from the other types until a thorough inspection is carried out.
Illustrated Examples Of Tire Sidewall Bulge
To give you a clear understanding of what a tire sidewall bulge looks like, we have provided some illustrated examples:
- Belt separation bulge: The bulge is wide and flat, and often has a long crack on the tread surface.
- Impact bulge: The bulge is small, round, and usually found at the edge of the tire.
- Overloading bulge: The bulge is small, and it may appear slightly higher than the other parts of the tire.
- Manufacturing defect bulge: The bulge is usually small and hard to notice, but it may have a wavy appearance.
Tire sidewall bulge can cause a significant problem if left unnoticed. It’s important to inspect your tires regularly and address any issues you find. By understanding the different types of bulges and their characteristics, you can identify the root cause of the problem and take the necessary steps to prevent it from happening again.
Causes Of Tire Sidewall Bulge
Tire sidewall bulge, also known as sidewall bubble, can occur due to various reasons. Before we delve into the causes, let’s understand what sidewall bulge is. It appears as a visible protrusion or bulge on the side of a tire.
The following are the possible reasons for tire sidewall bulge.
Overloading The Vehicle
One of the primary reasons for tire sidewall bulge is overloading the vehicle. When your car carries more weight than its maximum capacity, the tires’ sidewalls undergo significant stress, which can lead to sidewall bulges.
Here are some key points to remember regarding overloading:
- Overloading can cause severe damage even if it is for a short time.
- Make sure to check the tire load capacity in your car owner’s manual.
- Always remember to stick to the manufacturer’s recommended limit when loading the vehicle.
Over-Inflation Or Under-Inflation Of Tires
Another cause of tire sidewall bulge is over-inflating or under-inflating your tires. When a tire isn’t inflated correctly, the sidewalls have to bear an excessive amount of pressure that can result in sidewall bulges.
Some crucial things to keep in mind regarding tire inflation include:
- Check your vehicle’s recommended tire pressure and fill them with air regularly.
- Avoid inflating your tires above the recommended pressure level.
- Ensure that your tires are inflated to the appropriate level, as suggested by the manufacturer.
Hitting Potholes Or Curbs
Hitting potholes or curbs is another reason for tire sidewall bulge. When you drive on rough roads or hit potholes, the sidewalls may develop a bulge or bubble, which can lead to a blowout.
Here are some key points to remember:
- Avoid driving on rough and uneven roads.
- Make sure to slow down when you see a pothole on the road.
- If you accidentally hit a curb or pothole, inspect your tire for any damage.
Poor Tire Maintenance
Neglecting tire maintenance is a common cause of sidewall bulge. Regular tire maintenance is necessary to ensure proper inflation levels, tire rotation, and alignment.
Key takeaways for tire maintenance include:
- Inspect your tires regularly for any signs of damage or bulges.
- Check your car owner manual for recommended tire maintenance schedules.
- Make sure to rotate your tires every 5,000-7,000 miles to ensure even wear.
Age Of The Tire
Lastly, the age of the tire can be a reason for tire sidewall bulge. Over time, exposure to the elements and wear and tear can cause the tire to develop a sidewall bulge.
Some key takeaways about tire age include:
- Tires should be replaced every six years on average.
- Check your tire for the manufacture date (written on the sidewall) to determine the age.
- Even if your tires have plenty of tread, they may still need replacing if they are too old.
Tire sidewall bulge can happen due to various reasons. Regular tire maintenance, following the recommended load capacity, and ensuring proper inflation levels can help prevent tire sidewall bulge. Remember to inspect your tires regularly for any signs of damage or bulges and get them replaced if necessary.
Warning Signs
What Causes Bulge In Tire Sidewall: Warning Signs
Tires are one of the most vital safety features on any vehicle. They keep us stable on the road, provide traction, and absorb shock. However, even the smallest problems with a tire can cause significant issues, such as bulges.
Visual Inspection Of Tire
One way to spot tire bulges is through visual inspection. This process involves physically examining the tire for any abnormalities. Below are the key points to look out for:
- Check for bulges on the sidewall or tread area of the tire
- Look for cracks, cuts, or any other damage to the tire
- Inspect the tire for uneven wear patterns or worn-out treads
- Ensure there are no foreign objects embedded in the tire, as they can lead to bulges
Touch Inspection Of Tire
A touch inspection involves running your hands over the tire’s surface to feel for any abnormalities. These are the key points to keep in mind:
- Run your hand over the tire’s sidewall to feel for any bulges
- Check the tread area for any areas that feel lower or higher than others
- Be on the lookout for any lumps, bubbles, or rough spots on the tire
Monitoring Tire Pressure
Maintaining proper tire pressure is crucial in preventing bulges and other tire problems. Here are some key points to keep in mind:
- Check your vehicle’s owner’s manual for the recommended tire pressure level
- Use a tire pressure gauge to check the pressure of each tire regularly
- Adjust the tire pressure as necessary to maintain the correct level
- Avoid overinflating or underinflating your tires, as both can lead to bulges
Vibrations And Unusual Vehicle Movements
Finally, vibrations or odd vehicle movements can be a sign of tire bulges and other tire problems. The following key points can help identify these issues:
- Be on the lookout for any unusual vibrations or shaking while driving at high speeds
- Pay attention to any pulling to one side or the other
- Keep an eye out for any vehicle wobbling or swaying while driving
To conclude, a bulge in your tire’s sidewall can be a serious issue that requires immediate attention. By performing regular visual and touch inspections, monitoring tire pressure, and paying attention to any unusual vibrations or movements, you can prevent tire bulges and keep your vehicle safe on the road.
