The nosewheel while attached will likely leave a track less distinct that that from a tractor.
Weight of aircraft approx 60 tonne, if equal weight on all three axles
Axle weight 60/3 = 20 tonne
Weight of tractor possibly 2 tonne
Axle weight 2/2 =1 tonne
So a possible 20 (10 tonne per wheel) tonne weight will leave less distinct mark than 1 tonne (1/2 tonne per wheel)?
I accept that the weight balance of an aircraft will lead to differing weights to the above but cannot accept that the nose wheels would have a low figure (otherwise the nose would be bouncing into the air)
