Tire performance is directly influenced by its tread formulation. The addition of novel materials to the formulation is crucial to extend the magic triangle of tires. In this study, different amounts of epoxidized natural rubber (ENR) were introduced into the reference tire tread compound, and the changes in wet grip, rolling resistance and abrasion resistance properties were investigated. The replacement of NR with ENR leads to an increase in cros-link density and filler–filler interactions, while reducing compatibility due to localized aggregation effects of ENR.

• The characterization and mechanical behavior of ENR in tire compounds
• How replacing NR with ENR influences compound properties
• The expected performance in tires, such as improved flexibility at low temperatures and increased stiffness at high temperatures
