What I thought was a nosewheel shimmy at about 25 knots on the ground turned out to be coming from the mains. Discovered this when I fast taxied to get off a long runway, and the nosewheel came up, but the shimmy continued.
New tires on the mains solved everything. Rolls perfectly at all speeds now.

We then replaced the right main tire and brakes and he problem went away. Not saying this is the fix but it worked for us. No issues since.
