1. The matrix: most of the single steel cord form (or rayon, nylon, aramid fiber, etc.)
2. O belt: 3-4 layer composed of steel cord
3. The shoulder pad: matrix and belt between the middle layer
4. The bead: steel wire ring, upper and lower triangular rubber core, wire - reinforced layer and bead rubber components
5. The tread of upper and lower rubber tread: Rubber
6. The sidewall
