Sidewall Stiffening Architectures: MichelinLast 5 Years Research Landscape

Standard sidewall elastomers lack the structural integrity to prevent delamination and ozone cracking while maintaining the necessary rigidity for tire endurance.

What technical problems is Michelin addressing in Sidewall Stiffening Architectures?

Environmental Degradation and Tearing

(14)evidences

Standard diene elastomers suffer from ozone-induced cracking and low puncture resistance when exposed to external atmospheric stressors and mechanical impacts.

Structural Delamination and Peeling

(17)evidences

Cyclic loading at the bead and crown interfaces causes separation between the carcass reinforcement and internal stiffening elements, leading to premature structural failure.
