Abstract: A tool for the insertion of valve stems in the wheel rims for tubeless tires is disclosed. The tool avoids the common practice of removing the tire from the rim for replacement or insertion of the valve stem. The tool is entirely hand powered and operated and comprises a push rod slidably mounted in a body sleeve which has a tapered internal wall with a very slight included angle, less than 10*, so that the rod can be pushed with a minimum of force to compress the bulbous end of the stem until it is discharged into the hole of the rim. The discharge face of the sleeve has a tip that inserts into the hole with an outside shoulder that bears against the rim as the rod is pushed through the sleeve to steady the sleeve and hold it in place.
