This paper presents the modal analysis of car?s wheel rim of Aluminium Alloy under the value of speed 100km/h. The model of wheel rim is drawn by using SolidWorks 2014 and analysed by ANSYS 14.5. The wheel rim is P205/75R*15. There are many forces acting on the wheel rim. Inflation pressure acts on the rim at 241kPa. Principal stress theory, von- Mises stress theory, deformation and natural frequency equations are applied by theoretically and numerically. The results from theoretical and numerical approaches of frequency of wheel?s rim are compared. Working frequency of wheel?s rim is 150.9876 Hz. Working frequency does not match with natural frequencies of wheel?s rim at tenth mode shapes. Therefore, the wheel?s rim has no tendency of resonance.
