OMG, I hate to tell you, but you're the first tire presser ever, that keeps the customer's garbage! In 15 years of dealing with various tire pressing places, the first thing they say is " I dont keep the old tire, you take it with you"
It is not profitable for you to dispose of garbage. Scrap dealers wont take it, if they see it!
I had to get rid of lots of the wheels, was a pain, but I was paid by my company.
To avoid losing time hauling these, i simply put them out to curb at my house. I would use scrap metal a bait, and scroungers would take the whole lot. They said that if they put these with all the other metal, they could dump it with the mix and scrap dealers take it. Keep your metal scrap and cut a deal with someone to take it all, no charge to you.
Start right now and put your foot down, no keeping other's garbage!

My best suggestion is to find an auto scrapper that takes scrap autos to a shredder and
offer them to them. They can throw several old fork truck tires (solids) into the cars
to be shredded. Everyone can win.

Not really an option as these machines are a fortune and I have nothing to do with the end product as I'm in the forklift repair business, not in landscaping. Need a company that deals in waste tires that collects them.

Get a machine to pulp the tyres or grind them into small pieces.
The result has many uses. In the U.K. they can be seen in children's playgrounds - rubber mats, landscaping mulch, rubber products and mats, and rubber-modified asphalt.
