Just because the «outside clamping» range of a tire changer is twenty-one (21) inches, does not mean that this tire changer will effectively clamp a twenty-one (21) inch rim. A twenty-one (21) inch rim is normally LARGER than twenty-one (21) inches in diameter..
HMeasure a decorative wheel in your shop, and determine the exact measurement. (Include the rim lip) Remember that the clamping jaws need to have a clamping range of about two inches larger than the outside lip of the chrome wheel for the tire changer to be effective. The jaws need to expand out further than the rim’s edges for the rim to be properly positioned.
The jaws must also have enough «travel» (back toward the center) to exert the pressure needed to hold the rim in place. A tire changer with an «outside clamping» range of twenty-four (24) inches WILL NOT change a twenty-four (24) decorative rim. You will need a tire changer with a twenty-six (26) «outside clamping» range to change the twenty-four (24) inch rim.
