This system (or one VERY similar to it) has been discussed at length here once before. As 1Engineer will shortly describe in intricate detail, using the tire as the method to drive the track, reduces the efficiency of the track due to the limiting factor of resistance between the tire and the track rollers. This is also affected by the factor of how and how tight the track system is attached to the wheel and how much lateral or other off axis movement the track can have in relation to the wheel.
I'm sure that it may serve a purpose, but I think that purpose is mainly a fun factor and not a professional deep-snow traversing machine purpose :lookout:
