When turning with nose wheel steering, no differential brakes or thrust -
The tightest radius of turn occurs for points abeam the main gear.
Points ahead of the main gear have a larger radius of turn but pull away from objects to the outside as soon as the turn starts. With a swept forward wing you would have the opposite issue. You would need to account for obstructions INSIDE the turn before turning.
Points behind the main gear also have a larger radius of turn but initially move torards the outside as the turn starts. Some busses have a large rear overhang behind the axle and suffer the same effect.
To visualise the effects consider the limiting case with the nose steering wheels at 90 degrees to the direction of travel and with some magic propulsion system that didn't care about that - A tug for example. The size of the effect varies continuously between the two extremes, zero degrees and 90 degrees. In this case the aircraft pivots about the point between the two main landing gears.
Demonstrate it with a vehicle without wings. Much simpler to visualise and the effect is identical.
