The purpose of tracks is to lessen pressure on ground not to increase traction.
I have seen tracks on farm tractors used for skidoo trail grooming but they are always afraid of going through bogs and crossing streams where flotation not traction is the requirement.
Another not unimportant detail. If you want the tracks to go over the front and rear wheels you would need to be very careful not to use 4WD as there is a designed in speed difference between the two axles. The tracks would be fighting that difference.
Some tracks go around the rear tires and then a bogey wheel between the front and back axles becoming a bit like a half track.
The tracks will not dig into ice and hard packed snow but slide on top of it.
Chains, especially studded chains like those by TRYGG, are the way to increase traction along with more weight.
