I am at work killing some time. What is the break down of what is in wheel weights by percentage.
For clip-ons, supposedly .5% tin, 4% antimony, the rest lead with small fractions of other metals.
For stick-ons, pure lead.
Of course given they are NOT zinckies.

Clip On Composition: 2.96% Sb, 0.41% Sn, 0.174% As, balance lead
Adhesive Strips Composition: 0.377% Sb, 1.45% Sn, 0.029% As, balance lead
Percentage is from analytical testing done by a Cast Boolits poster several years ago

Composition of clip on WW's tend to vary with the manufacturer.
There is no set rule.
Here is a link to a good article on lead alloys.
