A tuned sidewall arc profile and bead apex height improve braking while keeping rolling resistance low through better ground-pressure distribution.
A sidewall rubber strip beside the bead lip boosts bead support and durability while lowering rolling resistance and material use.
Defined bead filler geometry and sidewall reinforcement balance steering stability, run-flat durability, and ride comfort.
Multiple rubber layers in the bead filler control bead deformation to cut tire weight, rolling resistance, and durability loss.
A bead-side transponder layout with layered filler rubber improves steering stability, limits rubber separation, and protects RFID communication.
Optimized inner and outer bead filler geometry balances run-flat support with normal ride comfort by controlling tire radial rigidity.
