Publication number: 20240059100Abstract: The present invention relates to compositions for elastomeric compounds for tyres, in particular for tyre treads, comprising particular reversible cross-linking agents, tyre components and tyres for vehicle wheels which comprise them. The present elastomeric compounds, due to their particular hysteretic behaviour, allow manufacturing tyres characterised by a lower rolling resistance during moderate driving and at the same time greater resistance to tearing and road grip during sports driving.Type: ApplicationFiled: December 21, 2021Publication date: February 22, 2024Applicant: Pirelli Tyre S.p.A.Inventors: Luca GIANNINI, Luciano TADIELLO, Silvia GUERRA, Thomas HANEL, Christoph WEDER, Stephen SCHRETTL
