Also, today I did baby's first independent tire change on my current chair. Usually I just have someone else do it. I got talked into solid tires on my next chair for less maintenance and because there's a LOT of constant construction in my area (lot of nails and glass), but I do really dislike that you can't change solids yourself without a bench vice. That doesn't matter though if I can't change a pneumatic tire myself so I wanted to see. So: Turns out I can change it independently, though it does hurt my hands a bit.
