Wheel weights of Pb are like finding quarters with silver content.
Diesel trucks and trailers still use Pb for their tires. Luckily for me and my brothers our father had about 2 tons of wheel weights melted down into Saeco 1 Lb. ingots. I am set for life. Now I just order Linotype ingots to mix with the wheel weight lead. The old man at one time had about 500 pounds of Linotype after printed newspapers started going away. It is harder to find now and expensive to have shipped. Roto Metals sells it for @ $5 Lb.
