What can the disposal of tyres and rims cost?

Hello together, I bought a used tyre set very cheaply or almost got a gift, which I can use with respect to the profile depth and the tire age still a few years. Unfortunately, the rims of the tyre set do not fit, so that I have to use my previous winter rims. Of course, the whole has to happen in a workshop. Finally, I stand there with 4 old winter tires and 4 steel rims, which have to be disposed of. I hardly think that it is worthwhile I am interested in what it may cost if I leave the old tyres and rims in the workshop for disposal. I ask because I just don’t want to be ridiculous or let myself be pulled over the table. On the one hand, I think that I have already read here in the forum that the workshops would sell the old tires themselves again; thus earn twice. On the other hand, I wonder if the rims are not “valuable” Waste metal are, for which a scrap dealer would pay even more extra. Where else could one dispose cheaply? At the local/common disposal center, which each community has in any form? (By the way, I had already had bad experience: A few months ago I wanted to give up waste oil due to special circumstances and would have been willing to pay for it too )> was not accepted.
