Reading Topic: Wheel weight removal
From an "aged" tire installer:
Clip-on weight removal - Not all of us have ready access to a wheel weight hammer, so usually a pair of needle nose pliers work or even a flat-bladed screwdriver to bend the clip away from the lip of the wheel.
Stick-on weight removal - Use a flat tipped screwdriver to pry up the sticky weights, don't worry if some adhesive residue is left over. Grab a bottle of degreaser (Purple Power, Greased Lightning, Simple Green, etc) and spray down the area throughly and rub down the area where the weights were attached thoroughly. Make sure to wipe away all of the degreaser.
