WDT P605-02 4.10-5 B-PR Tire Inner Tube Replacement

はじめに

Many small tires use inner tubes which are tubes that hold the air pressure for the tire. It is common for inner tubes to leak air pressure or get punctured. Replacing the inner tube is easy. The process requires you to remove the tire from the rim, swap the old inner tube with a new inner tube, and then reassemble the tire to inflate it.
