When Can A Tire Not Be Patched? Beginner’s Instruction

Patching is a measure to be taken when the tire has a flat condition. The causes of the above damage are due to being punctured by a sharp object, or the wall is not well resistant to friction from both sides of the body and the road surface, causing the thing to be worn away. 

In such cases, instead of replacing a new one, many people choose the economical repair and still ensure good quality.

So, when can a tire not be patched?

  • The hole is too big
  • Your puncture is in the shoulder area
  • It got stuck by a meteor
  • Run-flat tires
  • Other problems

The article will analyze each case in detail. Let’s check it out!

How Do You Repair Tire Punctures Properly?

The damage often is a hole, a leak of air, these are all minor injuries, and most are thriving. A common way to finish them is to thread a gas carrier wire inside through the leaks found. 

If the gap does not fit the hand, the worker will expand and stretch the wound with hot crude oils. Although the repair technique is quite simple, if the artistry of the mechanic is not good, the fixation is not in the correct position, it will affect the life of the whole wheel.

The plugs and straps support many risks of breakage during the airflow leading to bulging and misaligned conditions in the product.

So the correct way to repair the process is:

  • Altogether remove the wheel from the rim for a good look
  • Remove dangerous objects
  • Seal open mouth with a rubber
  • Fill gas, and finish firmly with supporting tools.

When Can A Tire Not Be Patched?

Depending on the case, the repair method is also different, but your tire cannot be patched anymore when you encounter the following conditions.

The hole is too big.

If the hole exceeds 6mm, you can never patch it. The larger the wound length, the higher the expansion problems; besides, the body structure is also gradually breaking down when the tearing of the air outlet is prolonged. 

Next is the wear indicator that touches the 2/32 inch; danger will happen at any time because the traction is no longer adequate when you drive.

Your puncture is in the shoulder area.

The tire’s sidewall is flexible and can be to a certain extent. When moving, the wheel is impacted by many objects such as gravel, etc. 

So in terms of structure, the internal body design is more solid. When cracks appear in the tire’s sidewalls, the stickers during the move will peel off, weakening the air cushion between the repair contact surface, causing air to continue to leak.

It got stuck by a meteor.

Damage from hitting a meteorite is actual. It was through the owner of the car. It looks pretty similar to commonly worn rocks, but the areas around the impact are melting because of the meteorite’s heat. So patching the damage is not possible.

Run-flat tires

With this type, the process of releasing air pressure at the beginning of a puncture is slow, so you can continue to run to the repair shop.

But this is not too recommended because while moving, the body pressure has inadvertently eroded the wheel’s surface, solving the problem by multiplying.

Other problems

Besides the signs we have outlined above, there are many other reasons why you can not repair the wheel. Specifically:

  • The tears appear too much, and the wear cannot be covered, making it impossible to repair.
  • The wear index reaches an alarming level, so it should be instead of a patchwork
  • Buy an older one, and if you don’t know the information, you can’t repair it
  • Metal pieces appear all over the sidewall of the tire.

Why Can’t A Tire Sidewall Be Patched?

There are many reasons given, but the main one is that the damage occurs too severely, or lasts a long time, causing many other tire factors. 

If you try to patch it up to repair, the air seal will not hold because the running wires will push the rubber sheet away from there, returning to the original condition.

When Can You Repair Tires?

When the tire has damaged problems such as holes or wear on the wheel, it’s time to have it repaired. For common punctures, depending on the location determines the injury’s severity. 

Regardless of exceptions, the hole is in the center of the tread, and the diameter exceeds 6mm; it is easy to fix. The patching method is also quite simple, but it requires an experienced professional to determine the correct position and force of the glue in the most accurate way.

Ideally, the tire should be complete from the rim for easy viewing, and the air outlet must fill, the wound mouth fixed from the inside.

Besides, you should regularly pay attention to the condition of the wheel to control the wear rate most surely. Driving to a service center is an effective way to protect both the tires and the body. Note that if the wear reaches the threshold of ⅔ inch, do not try to patch it but choose a new one.

Can Bubble Tires Be Repaired?

Bubbles in tires can be caused by many factors such as road conditions, lack of air pressure or weight overload, or manufacturing defects. The result of bubbles is the stretching of the layers in the wheel wall. 

This situation can be re-filling it with air, preventing the delamination process. If you want to be sure, you should go to the center for effective maintenance.


Detecting a wheel in trouble is relatively easy, but determining the tire’s extent is quite tricky. Although this problem occurs quite often, it also has aspects to pay attention to avoid, such as unrepairable cases to help save time and money.
