How to Patch an Inner Tube?

[LaBrody]

First, use a tire lever to pry open the bicycle's outer tire. This requires some force, but avoid using excessive strength to prevent damaging the good tire. Inflate the tube fully to locate the puncture. Then, use a file to roughen the area around the puncture on the tube to enhance the adhesive's bonding strength. Prepare a rubber patch for the tire repair, apply adhesive to it, and evenly spread adhesive on the tube's affected area. Then, attach the patch firmly. Gently tap around the patch with a hammer or press it down with your hand to ensure a secure bond. Avoid using too much force—just enough to make it stick firmly. Check for any remaining leaks. If none are found, deflate the tube, reinsert it into the outer tire, and inflate it fully.
