The plane that I bought also had been hanging for a long time. It had a brand new tire on it. it looked great, it even had the sticker on it. When we taxied at high speed, we got a wobble. Ground handling didn't seem whuite right either.
We jacked up the front of the plane and rotated tha tire. Although it did not have any obvious defects, it did not rotate true. Changed the tire and not only did the wobble disappear, the plane tracked better on the ground. Check the tire for out of round.

Is the tail low ? Even ground? All combined can affect ground handling pretty much. But a little gust can weathervane my Ercoupe too. Can you elaborate on "very gradually deviate from taxiway center line to the left and then to the right" ?

The ac has a dual fork nose gear and the tire is "new" as far as flying goes, but the tire has been on a hanger queen for approximately 5 years. It has no obvious deformity. When taxiing, with the control wheel held in the centered position, the plane will very gradually deviate from taxiway center line to the left and then to the right. The deviations are not minor in degree, but the ac has not (yet) departed the taxiway. All the linkages from the control wheel to the fork and nose wheel have been checked and are tight. The rigging has been checked and is all ok. This item is holding theup flight testing. I certainly hate to think of the landing roll out with faster speeds with the nose gear in its present state. The tires are going to be re-examined tonight but if the problem does not reside there, the mechanic is at the end of his rope.
