This kit is designed for temporary repair of punctures in tubeless tires on various vehicles, including cars, trucks, RVs, ATVs, tractors, trailers, and motorcycles. It is intended to provide a temporary solution to allow you to reach a professional tire service center for a permanent repair. Always prioritize safety and follow all instructions carefully.
2. Safety Information
- Always wear appropriate personal protective equipment, such as gloves and eye protection, when performing tire repairs.
- Ensure the vehicle is safely parked on a level surface with the parking brake engaged. Use wheel chocks if necessary.
- Never attempt to repair a tire that has damage to the sidewall, a large puncture (over 3cm), or a blowout. These types of damage require professional attention.
- This repair is temporary. Drive at reduced speeds and have the tire professionally inspected and permanently repaired or replaced as soon as possible.

5. Operating Instructions: How to Repair a Tire
Follow these steps carefully to perform a temporary tire repair:
- Locate Puncture and Remove Object:
Using the pliers, carefully pull out the foreign object (nail, screw, etc.) that caused the puncture. If the object is not visible, apply soapy water to the tire surface to identify the leak by observing bubbles. - Ream the Hole:
Apply a small amount of lubricating oil to the tip of the T-handle spiral probe tool. Insert the spiral probe tool into the puncture hole. Push and twist the tool in and out several times to enlarge and clean the hole, preparing it for the repair plug. This also helps to roughen the rubber for better adhesion. - Prepare the Repair Plug:
Remove one repair plug from its sheet. Thread the repair plug through the eye of the T-handle insert tool needle until it is about halfway through. Gently dip the needle tip and the repair plug into the jar of lubricating oil. - Insert the Repair Plug:
Remove the spiral probe tool from the tire. Immediately insert the T-handle insert tool with the prepared repair plug into the puncture hole. Push the tool firmly and steadily until about 1/2 to 1 inch of the repair plug is visible outside the tire. - Remove Insertion Tool:
While holding the sleeve of the insert tool firmly against the tire, pull the T-handle straight out of the hole. The repair plug should remain in place, sealing the puncture. - Trim Excess Plug:
Using the utility knife, carefully cut off any excess repair plug material, leaving approximately 1/8 to 1/4 inch of the plug sticking out, flush with the tire tread. - Inflate and Check:
Inflate the tire to the manufacturer's recommended pressure using a tire inflator (not included). Use the included tire pressure gauge to verify the pressure. Apply soapy water to the repaired area to check for any leaks. If bubbles appear, the repair may not be sealed properly, and you may need to re-evaluate or seek professional help.

6. Maintenance
Proper maintenance ensures the longevity and readiness of your tire repair kit:
- Cleaning Tools: After each use, clean the spiral probe tool and insert tool thoroughly to remove any rubber residue or lubricant. Use a cloth and, if necessary, a mild solvent. Ensure they are dry before storing.
- Storage: Store all components neatly in the provided storage case. Keep the case in a cool, dry place, away from direct sunlight and extreme temperatures.
- Repair Plugs: Keep unused repair plugs sealed in their original packaging to prevent them from drying out. Dried-out plugs may not create an effective seal.
- Lubricant: Ensure the lubricating oil bottle cap is tightly secured after use to prevent leakage or drying.
7. Troubleshooting
Here are some common issues and their potential solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Repair plug difficult to insert | Hole not reamed enough; insufficient lubricant. | Ream the hole more thoroughly. Apply more lubricating oil to the probe and plug. |
| Air still leaking after repair | Plug not fully seated; puncture too large/complex; plug material dried out. | Ensure plug is inserted deep enough. If the puncture is too large or complex, professional repair is needed. Use fresh repair plugs. |
| Insert tool stuck in tire | Insufficient lubricant; plug not threaded correctly. | Apply more lubricant. Ensure the plug is centered in the eye of the needle. Twist gently while pulling. |
