What is the function of the tire bead separator?

Supporting sidewall: helps the tire maintain its shape under load and prevents excessive bending of the sidewall. Improve rigidity: Enhance the stiffness of the tire bead area, improve steering stability and handling. Disperse stress: reduce stress concentration in the bead area and extend tire life. Sealing: The auxiliary tire bead is tightly attached to the wheel rim to prevent air leakage.
