The __ on the tire changer can hold the rim by grasping it from the outside or the inside, 8. Bead breaker b. Dismount tool c. Tumtable jaws d. Torsional damper

## Step 1<br />This problem is about understanding the parts of a tire changer and their functions. A tire changer is a machine used to remove and install tires on wheels. The question asks which part of the tire changer can hold the rim by grasping it from the outside or the inside.<br /><br />## Step 2<br />The options given are:<br />a. Bead breaker<br />b. Dismount tool<br />c. Tumtable jaws<br />d. Torsional damper<br /><br />## Step 3<br />The bead breaker is used to break the bead of the tire from the wheel, not to hold the rim. The dismount tool is used to remove the tire from the wheel, not to hold the rim. The torsional damper is used to absorb vibrations, not to hold the rim.<br /><br />## Step 4<br />The tumtable jaws, however, are designed to hold the rim by grasping it from the outside or the inside. They are the part of the tire changer that can hold the rim.
