Abstract

La présente invention concerne un pneu non pneumatique ayant des propriétés d'absorption des chocs et une force de rappel améliorées. Le pneu non pneumatique selon la présente invention présente des avantages en ce que l'absorption des chocs vis-à-vis des impacts transmis lors du contact avec le sol et la force de rappel d'un rayon principal après contact avec le sol sont améliorées par des première et seconde nervures de renforcement portant le rayon principal, ce qui permet d'améliorer le confort de conduite et la stabilité de déplacement.
