If you already have them, I would recommend bending it to accommodate your tire. Buy a can of plasti-dip if you end up sacrificing the rubberized covering.
The first bend I would consider would be pulling the hook more perpendicular to the wall. Like this one:
different hook
At the angle you show, I imagine with fat tires, that hook would get tangled up with the adjacent spokes. Having the hook a lot more perpendicular to the wall would make it more parallel with the spokes, making spoke interference less of an issue.
