It’s a long story, but I have come into possesion (legally) of 4 used low profile/performance tires. I have no use for the things, they won’t fit my car and I really wouldn’t need such nice tires anyway. It seems a waste to junk them, as they still have nearly all of their tread depth.
Is there some kind of used tire outlet that buys them, like used books or CDs? Would a dealer or tire shop be interested or would they think I was crazy for asking? Could I donate them and take a tax deduction? Any ideas?
Put them on Craig’s List. I would put the price at 1/3 of the retail value. You’ll find someone to take them within a few days. All the usual cautions about Craig’s List apply
I don’t know about where you live but around here there is a used tire shop on just about every corner. You could probably get a better price selling to an individual on Craigslist, but a tire shop might be less hassle.
I know several people who buy and sell car parts, especially tires, on Craigslist. I would definitely try selling them there.
Any junkyard will be glad to buy them, I don’t know if they’ll pay much though.
I put mine out with a free sign. I thought I would have to pay the garage to take and dispose of them (I didn’t think they’d trust them to be resellable) and wanted them taken away anonymously with an implication of as is, where is.
I’ve bought used tires from newspaper ads before. Sometimes people have perfectly decent tires at a bargain price due to extenuating circumstances. Folks like me will gladly pay 1/3 of the cost of new tires if the tread looks fine.
Of course include the size (e.g. P225/75R15) in the ad.
People with no money are always looking for cheap replacements. Craigslist or e-bay or a sign on your tree out front will get 'em sold.
I put them on Craigslist (with size, brand, and other specifics) soon after I posted this. So far, 4 people have emailed to ask if the tires will fit on their car. Wishing to avoid a small claims appearance if someone were to somehow damage their car with wrong-size tires, I have politely told them to check with the dealership.
Then there was the guy with the 1998 BMW 3-series (so he said) who insisted that I was obligated to find out for him. I thoughtfully opined that I had no way of knowing what wheel option his car was originally sold with, much less if it now had differently sized aftermarket wheels. He threatened to report me to the FBI (maybe he meant the FTC) for ‘internet fraud’. I humbly suggested that he could go out to his car and read the size off the side of the tires himself. Haven’t heard back from him.
BMW drivers read craigslist?
It’s only one data point, but yes, delusional ones who never learned about punctuation.
And that’s why I put mine on the side of the road. 
“Life is just a tire swing”.
Which once again points out the difference between porcupines and BMWs. Porcupines have the pricks on the outside.
