It's worth rotating the cranks by 90 degrees, or the tyre, to even out
the tyre wear. The tyre scrubs on sharp turns, which are normally at
the same part of the pedal stroke, which is why you get uneven wear.
The wheel doesn't get localised stresses and wear in the same way. I
suppose it might if you do lots of hopping and dropping because you
will usually land witht he cranks horizontal, and probably usually with
the same foot forwards. However, for normal riding, I wouldn't worry.
Do get the correct tools to remove your cranks, though. Never try jobs
like that witht he wrong tools, because you will cause frustration to
yourself and damage to the unicycle. This will cause further annoyance
which may make you throw the unicycle at the wall in a fit of temper,
causing further damage to the unicycle and possibly to the wall. That
will upset you even more, and very probably annoy the owner of the
wall. This will lead to a spiral of anger, damage and further anger
which will escalate completely out of control.
It is a little known fact that if Adolf [censored] had bought a proper
crank removing tool in early 1939, and had not stripped a thread, lost
his temper and thrown his unicyle at his Polish neighbour's newly
whitewashed wall, World War 2 might have been avoided.
