What is a Tire Bubble?

Before we dive into the steps for fixing a bubble on your tire, it’s important to understand what exactly a tire bubble is and how it forms. A tire bubble, also known as a “blister”, is an irregular bulge or bump that appears on the sidewall of your tire.

It’s typically caused by air leaking between the layers of the tire, creating a separation or pocket of air. This results in a visible bulge, often around the size of a golf ball, and can also sometimes be accompanied by a hissing sound or even a flat tire. You may also notice uneven tire wear and steering issues while driving with a tire bubble.

11 Step-by-step Guidelines on How to Fix a Bubble on a Tire

Step 1: Assess the Damage

The first step when you spot a tire bubble is to assess the damage. Take note of where the bubble is located on your tire and its size. This will help determine if it’s repairable or not. You should also inspect the rest of your tire for any additional bubbles or damage. The last thing you want is to fix one bubble only to have another one appear a week later.

Step 2: Determine the Cause

Tire Bubbles Can Be Caused by a Variety of Factors

Tire bubbles can be caused by a variety of factors, including impact damage from driving over potholes or curbs, manufacturing defects, or even excessive wear and tear. Identifying the cause will help determine if it’s safe to repair the bubble or if it’s time for a new tire.

You may also want to check the air pressure in your tires, as underinflated tires can increase the risk of a bubble forming. It’s recommended to check your tire pressure at least once a month.

Step 3: Use a Tire Pressure Gauge

To accurately measure the air pressure in your tire, use a tire pressure gauge. This tool will give you an accurate reading and help determine if your tires are properly inflated. If they are not, you may need to inflate them before attempting to fix the bubble. If your tires are continuously losing air, it may indicate a more significant issue and you should consult a professional.

Step 4: Consult a Professional

If you are unsure about repairing the bubble yourself or are uncomfortable doing so, it’s always best to consult a professional mechanic or tire technician. They have the knowledge and experience to properly assess and fix your tire bubble.

But if you’re feeling confident, let’s continue with the steps for fixing a bubble on your tire. If you’re unable to safely drive your vehicle to a mechanic, consider calling for roadside assistance. Although it may cost a bit more, your safety is always the top priority.

Step 5: Gather Materials

You Begin Repairing Your Tire Bubble

Before you begin repairing your tire bubble, make sure you have all the necessary materials on hand. This includes a tire patch kit or plug kit, rubber cement, pliers, and scissors. You can find these items at most auto supply stores or online. It’s also a good idea to have a spare tire on hand in case the damage is too severe to repair. The last thing you want is to be stranded on the side of the road with no spare.

Step 6: Prepare the Tire

If you’ve determined that your bubble is reparable and have gathered all the necessary materials, it’s time to prepare the tire for repair. First, remove any debris or foreign objects from the damaged area using pliers or tweezers.

Then, use sandpaper or a wire brush to clean the area around the bubble and create a rough surface for the patch or plug to adhere to. It’s important to have a clean and rough surface for the repair to properly bond.

Step 7: Apply Rubber Cement

To ensure a strong bond, apply rubber cement to the inside of the tire around the damaged area. This will help seal any air leaks and create a stronger bond between the tire and the patch or plug. Allow the rubber cement to dry for a few minutes before moving on to the next step. But don’t wait too long, you want the cement to still be tacky when applying the patch or plug.

Step 8: Insert Patch or Plug

Depending on the size and location of your bubble, you will either use a patch or plug to repair it. A patch is typically used for larger bubbles, while a plug is more appropriate for smaller ones. Follow the instructions on your patch or plug kit to properly insert it into the tire, making sure to cover the entire damaged area. The patch or plug will act as a barrier to prevent air from leaking out.

Step 9: Trim Excess Material

Inserting the Patch or Plug

After inserting the patch or plug, you may have excess material sticking out from the tire. Use scissors to carefully trim any excess material, creating a smooth and even surface on the tire. This will help prevent the patch or plug from catching on anything and becoming dislodged.  You can also use a tire repair sealant to further secure the patch or plug in place. The sealant will create a strong bond and help prevent any future air leaks.

Step 10: Let it Cure

Allow the repair to cure for at least an hour before driving on it. This will give the rubber cement and tire repair sealant enough time to dry and create a strong bond with the tire. It’s recommended to avoid excessive speeds or sharp turns for the first 24 hours after a tire repair to ensure the patch or plug sets properly.

Step 11: Monitor Tire Pressure

After you’ve repaired the bubble on your tire, it’s crucial to monitor the tire pressure regularly to ensure there are no further issues. If you notice any changes in pressure or another bubble forming, consult a professional for further assistance. It’s always better to be safe than sorry when it comes to the safety of your vehicle and yourself.

Following these step-by-step guidelines on how to fix a bubble on a tire will help you safely and effectively fix the bubble on your tire. Remember to always prioritize your safety and consult a professional if you are unsure about the repair process. Regularly checking your tire pressure and addressing any issues promptly can also help prevent tire bubbles from forming in the future.  So, keep these tips in mind to maintain safe and smooth driving!
