But you lose a lot on each corner. Unless you notice you wheels are
spinning, you will lose more on the corners than you could gain. On the
road the advantage is to wheels on the straight - the smaller ground contact
patch allows for less rolling resistance. The advantage of the tracks is
more in the lower ground compaction factor than the traction - if the ground
is too soft for the wheeled tractor you shouldn't chance the tracks, even if
it would work.
Each modification you listed can help or hurt. Depends on too many factors.

Maybe, once again, there are too many factors. Everything is a trade off,
you can get better fuel economy if you don't mind blowing your engine up
every day. Most people can't afford a new engine every day, so we tune
things down a little.
