Improving structural integrity with Twaron®

The rise of EVs and heavier SUVs is reshaping tire design requirements. Tires must deliver higher energy efficiency while supporting significantly heavier loads. Increased vehicle weight often leads to multiple carcass ply layers, which can reduce energy efficiency. Twaron® enhances carcass reinforcement, providing reliable tire performance with an energy-efficient design.

Replacing two layers of Rayon or PET HMLS with a single layer of Twaron® provides a highly efficient reinforcement solution, enhancing energy efficiency by reducing overall tire mass.

The high modulus and tensile strength of Twaron® enable equivalent or superior reinforcement performance with fewer layers, minimizing material usage and reducing hysteresis losses. This contributes to improved rolling resistance and energy efficiency.

Twaron’s single-layer construction reduces internal strain and compression, enhancing overall structural consistency and minimizing the risk of fatigue-related failures in the inner sidewall.
