How to Handle the Issue of Bulges on the Tyre Sidewall?

If you want your tyres to perform well on roads, you have to keep them fit and fine for a long time. The performance level of car tyres depends on their mechanical condition.

Sometimes driving conditions are favourable for Tyres Reading and sometimes they are not. Unfavourable road and weather conditions make car tyres weak and prone to different mechanical faults.

Therefore, old tyres show a lot of warning signs, such as tread wear, bulges and cracks.

The presence of these signs on the sidewall or tread makes it very clear that your tyres are near retirement. So, change your tyres before they become unable to meet your driving objectives.

To detect warning signs, you have to check your car tyres regularly. You will be able to make good decisions after observing cracks, cuts or bulges on the sidewalls of your tyres.

in this blog, we will talk about only bulges that take place on the sidewall of car tyres to increase the worries of car drivers.

Why do tyre bulges take place on tyres?

Bulges in tyres take place when internal parts of car tyres experience impact damage. Damage in the inner parts may take place in the form of torn parts, holes, or leakage of air. These issues lead to the presence of one or multiple bulges on tyres.

However, this is a rare case but manufacturing defects may cause bulges in tyres as well. Manufacturing defects take place when the glue cannot hold two layers together successfully. As a result, layers develop a gap to form a bulge on the sidewall.

wrong air pressure in tyres is also a reason for tyre bulges. improper inflation causes excessive heat in car tyres. this condition leads to weak bonding between multiple layers of tyres. As a result, tyre bubbles may take place in tyres.

One or multiple bulges may take place on the sidewall because of overloading. if you drive your car with a heavy load, internal parts like piles and steel wires may experience extreme pressure to face serious damage. Damage to these tyres may lead to the formation of tyre bulges.

The coating of tyre rubber works as a protective layer for the skeleton of car tyres. Tyre rubber degrades because of heat, friction, ageing, weather, and driving habits.

What does a sidewall bulge indicate?

If you observe a bulge on the sidewall of your tyre, you have to be aware of the internal damage in the tyre. Since a tyre with sidewall bulge is internally not in good condition, it would not be able to run on roads with optimum strength. Driving on these faulty tyres is going to make the condition worse in the future. Your tyre may explode because of potholes, kerbs or similar hard objects if it has a sidewall bulge.

Can you repair a tyre bulge?

You should not try to repair your tyre if you have observed a bulge on its sidewall. The presence of a bulge on the sidewall means the tyre would not be able to function efficiently on roads due to a sick internal structure.

Repairing faulty internal structures is not possible for a mechanic. So you should replace your faulty tyres with a new set as soon as possible.

If you drive on the same tyres, the size of the bubble will become larger because of air pressure. So, the problem is going to increase if you do not change your tyres at the correct time.

Therefore, wasting time on repairing works is not a good idea. Contact a tyre dealer and buy a set of new tyres.

Is it safe to drive your car on bulged tyres?

No, it is not a good decision to drive the vehicle on a tyre that has bulges in its sidewall. If you have to drive your car with a faulty tyre, slow down your speed because high speed, friction and heat are not favourable for a tyre bulge. Moreover, even a single hit with a hard object can explode your tyre because of a tyre bulge. Moreover, check the air pressure in the tyres because high air pressure is not a good factor for your tyres in the presence of a bulge.

This is the best approach if you change your car tyres if you observe one or multiple bulges in their sidewalls. 

How to prevent tyre bulges?

Preventing tyre bulges is possible if you improve your driving habits and maintain your tyres effectively.

Avoid hard objects like kerbs, potholes and bumps since they are the main obstacles to damage the internal structure of your car tyres Reading.

Moreover, always keep the inflation level in your tyres at the optimum level. Low air pressure may increase pressure on the internal components of tyres to create a bulge.

Additionally, consider the speed limit and loading limit of your vehicle. Increasing the speed of your vehicle is responsible for a higher level of heat and friction to degrade car tyres. Similarly, overloading also keeps your tyres under pressure and this condition generally leads to the formation of tyre bulge.


Tyre bulges are not favourable for the performance of your vehicle. Therefore, you must change your tyres after looking at various swelling areas on your tyres. If you are looking for repair work, you must know that repair works for some faults in tyres are not possible and bulges are included in these faults.
