Bead Filler
The bead filler is a wedge of stiff rubber compound positioned above the bead bundle that provides the transition between the rigid bead and the flexible sidewall. A harder bead filler gives sharper steering response and more precise handling, while a softer filler improves ride comfort. It is functionally equivalent to the apex in tyre construction terminology.
