I don't think that wheel weights are hard (why would they be?).

They are. They are generally 0.5% antimony and 0.25% arsenic - the
rest being lead - and they are heat treated for hardness.


Do you know why they need to be hard?

So they stay tight against the rim and don't bend under centrifugal
force. at 1000 RPM on a 15 inch rim, a 1 oz weight weighs 13 1/4 lbs,
before it hits a bump.


Ayup. Tape weights..which are taped to the inside of the rim are
generally pure lead..because they are being loaded against a flat rim
and are not subject to being torn off
