Best when used in conjunction with the ESCO 70100 Easy way truck tire demount tool. A much more affordable option that purchasing an expensive heavy truch tire machine. Simply place the tool's wedge hammer tip between the tire side wall bead and the rim flange. Then press down. The spring loaded action reduces technician fatigue and provides optimal impact speed and return speed. This is the ultimate 1 - 2 punch for serious truck shops that want to provide a valuable and profitable service, without a huge investment.
