LandRover tried this in the 60's, with a long wheelbase model. Like the 
current posting, it had a cog in place of the road wheel, with two little 
road wheels inside the track belt. Made for a little triangular track in 
place each the road wheel. Installation was the same as changing a tire! 
Never made it into production however.   tim s.
