The present invention further provides a tire ring tool used in connection with a
retaining ring and a raschig ring for securing a solid tire on a rim, the ring tool including a handle and a lifting end extending generally radially outward from the handle. The lifting end has a body portion that curves axially inward as it extends radially outward and terminates in a tip and a projection extending radially outward from the tip, where the projection has a lesser lateral dimension than the tip, and the tip extends laterally outward of the projection to form a shoulder.
