They usually buy tires from salvage yards; you won't get much out of them. Given the extremely unusual size of those tires, they probably would. Some tire stores buy used tires, but not all tire stores do. You should contact local tire stores in your area and see who buys used tires. When you find out which local stores buy used tires, ask about their purchasing policies and what types of tires they accept.
To get the most out of your tire offerings, it's best to explore all your options with companies that buy used tires. Some come with low rolling resistance tires and mileage may be compromised if tires are changed. In fact, the sale of used tires is encouraged, considering that the United States throws away 290 million tires every year. Big Industrail tires can give you pretty good credit. Before, you could sell good cases to reusers, put them on Craigs List or on the local bulletin board (I bet you want to keep them long, if you sell them, for example, in half at retail), I have no qualms about buying tires like that, and I'm also an avid recycler.
The process of sending used tires to the recycling plant is actually an additional expense for auto repair shops. While there may be a large number of retreaders in your area, the best way to find one is to check out the Retreading and Tire Repair Information Office published by the Retreading and Tire Repair Information Office. This is also a sustainable way to extend the life of used tires, instead of throwing them away as soon as buy new tires. If this were in a high-performance car or one that was used on the track from time to time, there might be some justification for changing tires, but in the daily shopping of a driver at the supermarket, getting new tires is a waste of money in my opinion.
You should first call your local Discount Tire dealer to make sure they accept used tires for recycling and if it's free or has a cost. Some can accept any type of tire, but they are stricter about the quality of the used tire they accept. If you search for tires on Craigslist among the auto parts for sale, you will undoubtedly find used tire dealers. To start selling used tires online on eBay, you'll want to create a detailed listing that includes photos from different angles and information about the tire.
If you are sending the tires to a retread, an inspector may need to inspect and check them.
