Patented design offers one piece construction, and assures long life for many tire changing applications. New rounded tip ends insert easily and will not cut or rip bead or sidewall. The new design makes it easier to mount and demount tires without changing the way the tool is used. Stock: 3/4". Made in the U.S.A. Mount end: precision forged knob grips rim. New design won't slip during tire mounting. Special curve design always grabs the bead edge. Demount end: precision-forged angled tip slides between bead and rim easily. Forged design won't slip when demounting the second bead.
