You cant use simply the track and wheelbase, as the center of the turn radius is not always the inside set due to wheel drag, ie the inside wheels dont pivot on the axis, but the theoretical center of turn is inside this, sometimes very far with multiple sets. There is also the max angle the nose gear can turn, which varies significantly by aircraft. On the 773 wheels are 5.5m from centerline, so turn center pivot point is about 10m from the gear...
Also depends on what the OP meant for taxi ways, and associated turns on those...
