I've not had any problem with wind and the wheels pushing around. I don't think with the weight upfront and two wheels it has any of the problems that a solid wheel on a motorcycle causes.
I've also not had a chance to remove the wheel and check the weight.
I will say they are super easy to clean. It's a solid painted surface, I wash it just like I would a painted panel. Hit it with a little instant detailer when I pull up to a meet.
