This means if the puncture on the tire is at the sidewall or tire shoulder, you can not apply the patching or plug on these places. 

What is Sidewall? 

The sidewall is a very important place on the car tire that is responsible to hold all the pressure inside the car tire and the load of the car. So, the stresses on the sidewall are very different and high at the sidewalls. And you can not apply regular paths or tire plugs to repair punctures on the sidewalls. 

Shoulder of a Tire 

Also, the shoulder means the curvature between the threaded section and the sidewall of the tire. You can not also apply patches or tire plugs to repair these sections. The general reason for this, is these are the sections that are prone to be most punctured. And if there is a weaker point such as a plug or patch on the shoulder, it is a very high probability that you will have big blowouts. 

How to Measure the Pacthable Area? 

Doint is a very simple process. First of all, you need to locate the side of the threaded section of the tire from the inside side. All the measurements must be made according to the inside section o the tire. 

After you locate the correct position of the threaded section, measure 6 mm offset from the side of the threaded section from the inside. 

Draw a circumference line that goes through this offset around the tire. The puncture must lay completely inside that line. This means you can easily apply a patch or plug without any problem. 

Occasions to Do Not Apply Tire Patches 

Also, you need to know the occasions that you can not apply tire patches to your tire damages. This is a very important thing that you need to consider.

  • If your tire has multiple injuries and patches and plugs, do not apply a tire patch on your tire. Because you will hurt the structure of your tire. And the total durability of your tire will be reduced.

If you use your car in an overload position, this will make much higher stress on your tires. And the possibility of punctures will increase.
  • Change the tires: In every 10.000 kilometers, change the places of the tires between themselves. For example, if the traction of your car at the front side, you need to change the tires on the rear side every 10.000 kilometers. Because the tires at the traction side will become old faster. 
  • Check and maintain your tires: Always check the depth of the treads and maintain your tires to the best available tire pressure for your car. 

Quick Application of Plugs and Patches 

The application of plıgs and patches are generally easy thigs that you can easily apply to your wheels.

  • Then by using the lever, remove the tire from the rim.
  • After removing, the tire, remove the part from the tire with care. Clean the surface around the puncture by using sandpaper. The surface provides a very good attachment section for the glue. 
  • Apply the patch and apply glue after it. And hold it for 5 min. After that, you can remove the excess parts of the patch. Be sure that all the hole is closed by the patch.
  • After that, you can attach the tire to the rim by using a lever. 
  • Inflate the tire by using the air pump. 

As you see, the application of the patch is very simple. 


A plug is nearly the same as a patch. The only difference is, you need to attach the plug to the punctured area after the steps that we explained above. And take the plug with the help of a plier. Remove the excess section to get a plain and even surface. Attach the tire and inflate.
