Stiffness Analysis of Two Wheeler Tyre Using Air, Nitrogen and Argon as Inflating Fluids

Vertical radial stiffness for Ceat 90/100R10 tyre was measured using three different inflation fluids Air, Nitrogen and Argon. Tyre stiffness plays an important role in vehicle ride comfort, stability and damping of vibrations. The stiffness was measured using Load-Deflection method for different inflation pressures, inflation fluid and gradually increasing load in static condition. The stiffness was analyzed at inflation pressure [24, 26, 28, 30, 32, 34 psi] and load range [20, 40, 60, 80, 100, 120, 130, 140, 150 kg] for different inflation fluid filled in the tyre.
