I saw this question posed awhile back here. Last week I picked-up 334 pounds of wheel weights and here is the break-down:
Lead COWW = 54.5%
Stick-on weights = 19%
Steel weights = 13.5%
Zinc weights = 7.5%
Trash that included the stick-on composite stuff = 5.5%
I am in Iowa, the shop is still installing lead weights, we haven't banned them yet here! Over 73% by weight, is usable product.
So I should net out around 170 pounds of COWW ingots and over 60 pounds of soft lead ingots. To me, sure it is still worth picking them up. I do all my tire business there so, my cost for the weights is nil.
I keep telling myself "No more", but when they ask you to come and get them...I hate to say no! My phone company buddy will also drop-off lead cable sheathing every now and then. I can always sell or trade some of this overage.
Is there still anyone wanting the zinc weights? I must have most of a medium flat-rate box of them now. If not they will go with the steelies into the scrap iron pile.
