Question

the 2+ layers of cord that that sit under a tire’s tread: sidewall bead filler cord body beads tread belt plies inner liner

Explanation:

To determine the correct answer, we analyze the function of each tire component:

• Sidewall: Protects the tire's side, not under the tread.
• Bead Filler: Fills the bead area, not under the tread.
• Cord Body: Provides structure but isn't the layers under the tread.
• Beads: Anchor the tire to the rim, not under the tread.
• Tread: The outer contact layer, not under itself.
• Belt Plies: Consist of 2+ cord layers under the tread, reinforcing it.
• Inner Liner: Retains air, not under the tread.

Answer:

Belt Plies
