If uneven wear is a problem, it need to have the front end looked at; especially after you hit a curb.Assuming tires are not undirection, and uneven wear becomes a common problem. I would think the front wheels would be swapped as has been stated already. Fun part would be the rear wheel, I don't know if it would be a practical idea, but a rim that could be mounted to the swingarm on either side might work. That way during tire rotation you would just remove the rim, flip it then remount it. Would not have to remove the tire from the rim to flip it that way.
