Usually the garage getting rid of the old tire has to pay to do it. They are just passing it on to you.
I have no problem with that--not my point though.
I haven't been around as long as some, but IIRC there were no disposal fees prior to the provincial gov'ts disposal/recycling program. Recycling program starts, a per tire disposal fee is collected... Recycling program ends, tire disposal fee is still collected to this day.
Have the fees collected since then still been applied to disposal/recycling costs, or can they be found in the linings of various wallets?
