In addition to the information presented, you need to consider what happens when a rock or debris get on the tracks and try to wedge themselves between the tire and the tracks.
It does not take much to remove the little bit of slack in the tracks. With air filled tires, the tire can give or blowout if the debris are too large. With solid or filled tires, either the track has to break or axle/axle tubes have to give.
If the tire can't flex, the tracks will be put under additional stress which can cause them to wear out more quickly or just fail.
With over the tire rubber tracks, it is recommended to remove the front drive chains to keep from wearing out the chains and sprockets.
With the rubber tracks under tension around the tires, you have to be especially careful to keep the debris out of the tracks. With no spaces in the tracks to let anything out you can cause damage to the tracks or machine fairly quickly.
