MAIN
FUNCTION
-Road-contact and friction
- Traction and adhesion
- wear-resistance
- Lateral, circumferential, radial stiffness
- ensure tread-area and aspect-ratio
-Radial stiffness
- Inner pressure generates tensile forces in the
carcass-cords
- Air-tightness
- Impact / UV resistance
- Stiffen the bead-construction
- Prevent uncontrolled movement of bead-core
Prevent carcass-cords to be pulled out
- Ensure the rim-seat

Bead Core
- Anchor the carcass
8
Apex
- Bead endurance
