Modern tracks are built from modular chain links which together compose a closed chain. The links are jointed by a hinge, which allows the track to be flexible and wrap around a set of wheels to make an endless loop. The chain links are often broad, and can be made of manganese alloy steel for high strength, hardness, and abrasion resistance. [43]

When the tread depth becomes too shallow, like for example below 3.2 mm (4/32 in), the tire is worn out and should ...
