1.What is a tire bead separator?
The bead filler or bead apex is a critical component inside the tire, located in the bead area (the part where the tire comes into contact with the wheel rim). It is a wedge-shaped filling strip made of high hardness rubber, installed above the bead wire, used to support the sidewall and enhance the bonding strength between the tire and the wheel rim.

2.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.

3.What are the effects of damaged tire bead separators?
Tire sidewall bulge or deformation
The tire and wheel rim are not tightly connected, resulting in slow air leakage
Reduced handling and shaking during high-speed driving
In severe cases, it may cause tire bead tearing, posing a threat to driving safety.

4.How to determine if the tire bead partition is damaged?
Visually observe whether there are cracks, deformations, or bulges in the bead area.
Feeling abnormal steering wheel vibration or vehicle deviation while driving.
It is recommended to regularly visit a professional tire shop for inspection, especially after driving on bumpy roads.
