OK.... I am not Frick and Frack...... but I can tell you that wobbles typicaly won't come from hubs on these things. If you are worried about this, or convinced, then take them to a machinist and have the turned. That will tell you if they are out of round or somthing.
These were not designed for on road use or presure over 5 lbs in the tires. They should be 4-5 lbs, and off road. There you should not feel a thing.
