This car tire repair tool is designed to easily and quickly repair punctures in tubeless tires on most vehicles. The tire plug features a spring-loaded mechanism that drives the plug into the hole. The plug's shaft expands under pressure to seal the puncture, while the mushroom-shaped head secures against the inner tire wall to prevent air leakage. To use, clean and prepare the puncture by removing debris with the included cone-shaped tool, inserting it repeatedly to clear the hole. Load the appropriate rubber plug based on the size of the puncture. Apply lubricant to the insertion end of the plug and insert it into the tool. The thin tube pushes the plug into the cavity with a tapered tip. Advance the plug by following the markings on the tool barrel and select the correct rotation setting as indicated. Attach the plastic guide rod, selecting the appropriate size, and insert it into the tool. The guide rod, equipped with a plastic tip, helps align the plug during insertion. Insert the tool into the tire puncture, pull the trigger to deploy the plug, and push it into place. Once the rubber section is fully seated inside the tire, pull gently on the tail to ensure the mushroom head adheres to the inner wall. Trim any excess rubber flush with the outer tire surface. The tire can then be inflated and used normally. Note: This product does not include lubricating oil. Plastic guide rod tips are available in black and red and are shipped at random. Color selection is not available. Color: Black. Material: Plastic. Package Contents: 1 x Car Tire Repair Tool Set. Only the items listed above are included.
