You'd have to be brain dead, right? I wonder why there has bever been any discussion on balancing aircraft wheels. These little tires spin up to very high speeds compared to autos. I walked up and down the line of parked planes at the local airport(BVY) today and there was not a balance weight to be seen anywhere. Typically, the nosewheel is lightly loaded at its highest rotational speed at takeoff and landing so if a wheel is out of balance to begin with, shimmy would be most likely to occur at high speed. Have any of you with shimmy experience had your nosewheels cheked for dynamic imbalance?
