makes perfect sense to me.
smooth tread =more traction on pavement, so its harder to break loose to turn.
your other tires with more agressive tread actually have less rubber touching the road.
i would think inflating it to the max would reduce the contact patch, reducing the amount of rubber you have to break free to turn.
the lesss rubber contacting the road,the easier to break loose = turn.

I will be in contact.

Giving up is not an option. Good thing too, because this one-wheeled beast can be downright demoralizing.
