This research paper provides an analysis for the deformation and vertical stiffness of non-pneumatic tyres (NPT) due to different vertical loads. The non-pneumatic tyres are developed for replacing traditional pneumatic tyres. These tyres do not use air to support the load and subjected to hard conditions and rough terrain. The non-pneumatic tyres are used for heavy load-carrying capacity, vertical stiffness, contact pressure, and rolling. The mechanical characteristics of NPT are studied by using a 3D modelling software – Fusion 360 and analysed by using Finite Element Analysis (FEA) on the simulation software – Ansys.
