Step 1: Locate the leak

  • Fill the tires with air and check the pressure to ensure it reaches the standard. You can determine the correct pressure by feeling the firmness of the tires.
  • Create a mixture of soap and water, then spray it over the surface of the wheel. Look for air bubbles to identify the location of the puncture.
  • You don’t need to remove the wheel entirely for this step. Instead, use a jack to support the weight of the wheel, making the following steps easier to perform.
  • Using pliers, carefully remove the sharp object that caused the puncture. Locate the hole and apply appropriate repairs.

Step 2: Drill holes

  • Before proceeding with the next step, make sure to use a T-tool to close the hole properly.
  • Additionally, it is necessary to sand around the wound. Once the area is rounded, pierce the damage to the appropriate extent.
  • If the pin is too small for reaming, consider using a hand drill with a smaller tip to expand the hole.
  • Finally, machine the entire face for a professional finish.

Step 3: Plugs ready

  • Begin by preparing a strip of plugs from the kit.
  • Insert the repaired string into the eyelet using the plug tool.
  • Use pliers to pull the thread through the hook to the desired length.
  • Next, apply a layer of cement powder to cover both the thermos strip and the hole in the car’s body.

Step 4: Insert strip

Please press the plug securely into the hole. After inserting the pin into the muscle to a certain depth, leave approximately an inch outside the wheel surface, and then slowly remove the plug. Finally, securely position the end slot in the eyelet, allowing a smooth release as the pin enters the tire.

Step 5: Pump tires

First, refill the tires with air. Ensure that the pressure index is 10% lower than the standard. Then, spray a layer of solution onto the face to check if any leakage occurs again.

Step 6: Cut off the excess

To remove the cement coating, use a piece of paper and let it cool down for approximately 5 minutes to dry completely. Next, employ a cutter to neatly trim the cord, leaving only about ⅛ inch.

Step 7: Test

To ensure the gas is no longer fizzing, apply another layer of solution to the surface. Afterwards, remove any auxiliary equipment and allow the car to return to its original state.

FAQs About How long does a plug last in a tire

What Is A Tire Plug?

The plug method is a primary tool used for tire repairs. It is designed to seamlessly integrate with the tire, appearing like a standard wire while possessing remarkable adhesive properties. Depending on the situation, the plug can expand or contract to match the size of the hole it is fixing.

The working principle is simple yet effective: the plug wire senses the pressure once inserted into the tire, accurately determining the wound’s shape, and automatically expanding to provide a perfect fit.

Moreover, the plug wire’s material must meet strict quality standards, ensuring certainty and avoiding any potential issues when the tire is filled with air.

The plug method offers undeniable convenience, allowing repairs to be conducted without removing the tire from the rim. In certain exceptional cases, it can even be used when the wheels are connected. This method not only enhances efficiency but also provides an attractive solution for tire repairs.

Plugging or patching a tire is a temporary solution until a replacement can be obtained. While tire life after plugging can range from 7-10 years or 25,000 miles, it is important to note that potential issues cannot be completely ruled out.

In emergency situations that necessitate mobility, tire plugging can be a viable and effective option. However, it is recommended to prioritize replacing the tire for long-term reliability and safety.

Is It Safe To Plug In A Tire?

When traveling on certain road sections, it is safe to use plugged-in tires, which offer a longer lifespan compared to spare tires and can effectively prevent air from escaping through previous punctures. However, according to experts, a better solution than using a plug is the radial patch, a widely available method for popular tires on the market.

The process of using a wire to insert the air hole takes just a few minutes, while the overall repair process takes approximately 30 minutes. Both methods require vulcanization to enhance the strength and reliability of the rubber surface.

Traveling by car with reinforced tires is entirely safe, provided that the wound has been adequately repaired. It is recommended to use this method for a reasonable period of time after the repair.

In addition, there are some important notes to ensure stability when using this type of tire. However, it is not advisable to drive with a wound near the wall or on the side of the wheel. If the plug diameter exceeds ¼ inch, it is best to replace the tires.

Lastly, it is essential to consider the weight distribution. Avoid using plug tires to carry heavy objects, as this can inadvertently put pressure on the wheels when the tires are weak.

When can you use a plug?

The decision depends on the size and location of the hole. Plugs are commonly used for small punctures caused by nails, screws, or other sharp objects, and they are best suited for the tire treads. It is important to avoid plugging the sidewall. On the other hand, patches are suitable for slightly larger holes, typically under a quarter-inch in diameter.

Unlike plugs, patches can be closer to the sidewalls, but still not directly on the side of the tire. Patches are recommended for irregularly shaped holes, such as those caused by nails. By understanding these differences, you can make an informed decision about how to address tire damage effectively.
