I have a cheaper version of that.
Makes the job a synch. – lay it down use the bead breaker , turn it over , do other side, spray some tire soap about the bead , put it on the spike , bolt it down ,hook the bead and pull the lever round the spike,
To fit…..tire soap new bead , force first one over into the well of the rim , should go with minimal levering.
Hook the top bead under the rim , use mole grips on the weight lip to stop it popping off , hook the other end of the tire lever between bead of tire and rim , pull it round the spike. Tire is on.
