No. The plane is moving forward at 80mph. The wheels are the only thing
feeling the 160mph effect of the treadmill. This isn't a ground propelled
vehicle.

and a speedometer that
measures off of tire rotation would indicate the plane's speed (before
getting airborne) as 160mph, the speed relative to the conveyor.

While an airspeed indicator would indicate zero.
