Exactly this, the garages have to pay to dispose so they should let you take them for free, if you tell them what they are for they might even fit them for you too. There was a time when Id go through every tyre pile I found, it doesnt take too long before you end up with an impressive stock
this my garage is half full of them shame most are 17s tho and i wanna try and only run 18s from now on
