I think I found a clue. When I load the flight to start on the runway, it will not taxi off the runway. When you load the airplane cold and dark and push back from the gate and taxi, it seems to work fine. Any ideas?

Does this mean the taxiing doesn't work so good after you arrive, or before you take off, or both?

I just did a test, where I started on the runway, I took off, flew around the airport, and landed. I then taxied off the runway, and to a parking gate/ramp. Doing that, I found it was the same as it is when taxiing after starting from cold and dark.

Note. I was using the 777-200ER. The turns during taxiing are fine as long as the speed stays at, or below, 10 knots, turning was okay (slow but okay). I often brake slightly to assist the start of the turn. Also, the engines N1 was at between 37.0, and 44.0 during the taxiing.
