Tyre stiffness plays a crucial role in vehicle ride comfort, durability and stability. Tyre stiffness depend on
inflation pressure, tyre size, inflating fluid and loading condition. In this research work radial ply tyre size 165/70R13
and bias ply tyre size 165/80D13, check for it vertical stiffness by using Air and Nitrogen inflated tyre at different
inflation pressure and gradually increasing static load. Measurement done on radial ply and bias ply tyre at different
inflated pressure (25psi, 30psi, 35psi, 40psi) and different vertical static load (2000N, 3000N, 4000N, 5000N, 6000N) on
tyre using air and nitrogen. Different method used for measuring vertical stiffness of tyre but load deflection method gave
more reliable result as compare to other method. In this research work method was used is load deflection method for
finding the vertical stiffness of the tyre.
