I agree with Bob. What you're seeing is normal play in the bearings. 
They have internal clearance, so what you feel is that clearance 
multiplied by the length of the lever arm out to the OD of the tire.

The reason the play is more perceptable up and down is that the play 
is actually in a circle. The weight of the wheel/tire holds the axle 
to the bottom of that arc so you have to lift that mass up to the 
center of the circle in order to move it left and right. I think this 
would be more obvious if you removed the wheel.

What you're concerned about is normal.
