Currently, the tire industry is exploring eco-friendly tires with improved rolling resistance, traction, abrasion resistance, and fatigue properties. The present study investigates the potentiality of the hydrogenated styrene butadiene rubber (HSBR), a special and modified grade of styrene butadiene rubber (SBR) as a tyre tread tance and ozone resistance properties of the developed HSBR-based composites were critically evaluated and compared with those of conventional rubbers such as natural rubber (NR), emulsion styrene butadiene rubber (ESBR) and solution styrene butadiene rubber (SSBR) based composites. Interestingly, the HSBR-based vulcatance to thermo-oxidative aging, and ozone resistance as compared to the conventional SBR-based vulcanizates. The modulus at 300% elongation of the HSBR-based vulcanizate was approximately 74% and 11% higher than that of the ESBR- and SSBR-based composites, respectively, whereas the improvements in tensile strength were approximately 88% and 64% and the improvements in abrasion resistance were approximately 250% and 200% than that of the ESBR and SSBR vulcanizates, respectively. The tensile strength and fatigue resistance characteristics of the HSBR vulcanizate were also nearly similar to those of the NR vulcanizate. The findings demonstrate that HSBR can be a potential tire tread material with robust physico-mechanical properties and durability.
