Do you mean .05? or 0.5? for the dynamic inline friction?

I'm no physics master, but I'll take a guess.
Could this have anything to do with the coefficient of static friction being greater than that of kinetic? That is, when the wheel is in the forward direction it is rolling and therefore applies static friction, while the wheel is turned perpendicular to the direction of travel it slips and applies kinetic friction. Feel free to correct me if I'm wrong.
I don't know if this theory works because the wheel may also be slipping while the robot goes forward as either way there is barely any friction.
