A tire builder will also create the belt package at this point, adding two belts applied at diagonal angles, and folded over each other to increase strength. As well, a small fabric strip known as an overlay, is wound around the tire, helping to reinforce the tire's shape and structure at high speeds.
Lastly, a one-eighth of an inch-thick strip of tread is added. The tread is that thin because a racing tire is designed for heat resistance and grip rather than a long tread life.
Finally, the carcass and the belt packaged are put together, and an automatic roller presses them together. It is now a "green tire," and a barcode sticker is applied.
