I ride pretty rough terrain, but I also ride only tough, reinforced tires. Continental tires have lasted for me 7-8k miles and Schwalbe about 4k. I never wore out any winter tire. I say that my tubes
might live longer than tires as this is the statistics of small numbers. A tube cycles per year through a summer, late fall/early spring and winter tire. On the buying end, I presumably bought more tires over time than tubes, but on the disposal end they may be about equal. Even after something comes off the bikes, it goes into some buffer zone where it is used as a raw material for projects
