The ___ is the wearing surface on the outer circumference of the tire.

Explanation:
In tire anatomy, the part that actually contacts the road and wears down over time is the tread. It’s the outer rubber surface designed for grip and durability, with patterns to help channel water and improve traction. The other terms refer to internal or mounting components: the carcass is the body plies that give strength, the bead anchors the tire to the wheel, and the cords are the reinforcing materials inside the tire. So the wearing surface on the outer circumference is the tread.
