Both of those were with the T156 link, which was replaced by the T158 in the early '90s, adding 2796 pounds of weight to the tracks. I don't have reports on what sort of lifespan the T158 has had.

Note that this is still a great improvement on early tanks - the Mark I's treads lasted an average of 25 to 30 miles (and drive sprockets usually only lasted 20 miles).
T158 is supposed to be good for 2,000 miles of highway use. An extended range version is supposed to be good for up to 3,000 miles, planned for introduction in 2020-21.
The reason that the American Army does so well in wartime, is that war is chaos, and the American Army practices chaos on a daily basis.
