Publication number: 20240051351Abstract: The present invention relates to a self-supporting tyre (100) for motor vehicles which comprises sidewall reinforcing inserts (113A, 113B) with different stiffness. In particular, the sidewall reinforcing insert on the side of the tyre most stressed during driving is less rigid than the sidewall reinforcing insert on the less stressed side. The tyre of the invention exhibits a reduced rolling resistance and better comfort in normal driving and an unexpected increase in mileage in run-flat driving.Type: ApplicationFiled: December 22, 2021Publication date: February 15, 2024Applicant: Pirelli Tyre S.p.A.Inventors: Davide MIAZZO, Emiliano RESMINI, Luca CAMOSI, Luca GIANNINI, Dario SCALTRITTI
