Twin wheel nose gear can sometimes have a speed related vibration caused by the tyres not being worn to the same extent, (e.g. one new tyre fitted next to an older one), and/or excessive wear in the torque link joints. This vibration builds up towards a speed that induces maximum resonance somewhere on the airframe, then dies away as the aircraft accelerates.
