I bought a set of used tires due to a psychic experience back in 2001.
I was waiting for my E46 M3 to be built. My old car, a Nissan 200SX SE-R (two-door Sentra) has 120k miles, and the second set of tires were worn out. Being an SE-R, it had oddball size tires.
The military base I worked on had about 2500 people and a printed newspaper I almost never read. It had a classified ads section, which I had never read. Something made me pick up the newspaper and eventually thumb through the classified ads. There they were, a set of Bridgestone RE92s with 7k miles in the correct size for my car. Some Bubba had bought a new Mazda 3 "Sport" and decided the ride was too rough. HIs solution was to put larger diameter tires on the car. I'd earlier seen that Mazda in a parking lot with oversize tires and thought "That's f***ed up."
The RE92 is a "high-performance, all-season" tire. RE92s use soft, sticky rubber to improve performance. They were used as OE tires on a lot of Japanese econo-boxes, giving them acceptable performance despite the small tire size. Bridgestone still makes one size of RE92, and it has a US DOT treadwear rating of 260.

They have good performance, but have a low US DOT treadwear rating. I kept the 200SX SE-R another 7k miles before my M3 arrived. Frau Putzer brought a beat-up Honda Civic to the marriage. I ended up buying a new of new RE92s for it, and got 68k miles out of them. That was due to a combination of mostly rural and interstate driving and... well... you know what's coming next...
Tire Whispering. They were down to the wear-bars by then, though. I sold the beat-up Civic with 104k miles to a coworker for $900.
I've sold two vehicles with completely worn-out tires, that Civic and a Silverado 1500. The OE tires on the Silverado had 74k miles on them. For some reason I don't fully understand, I get a lot of satisfaction selling a car with worn out tires.
I was planning on keeping my 535i until 110k miles, when the third set of tires would have been worn-out. But thanks to one of those 'failure to yield types," my 535 with 98k miles and a set of PS 4Ss with 27k miles went to the junkyard instead.
