In this study, a new wheel rim design and static analysis has been carried out to enable ground vehicles to navigate better in unfavorable road conditions such as snowy, icy and muddy. This new designed wheel rim has a dynamic structure. On roads with adverse conditions, the rods on the wheel rim move linearly, tangentially to the sidewall of the tire to reduce the tire's contact with the ground. In this way, the contact pressure applied to the ground by means of the rod increases and the vehicle moves in these unfavorable road conditions. Although this study is design-based in order to examine the usability of the designed vehicle rim, a static analysis was performed under 5.5 kN force on one rod. The force applied to the rim was determined considering a vehicle with a mass of 1000 kg. The static analysis was performed using two different materials for the rim and rods. As advances in material technology significantly affect the usability of this proposed new wheel rim. But still, while aluminum alloy was preferred for the body part of the designed wheel rim, an analysis study was carried out using titanium alloy in the rods on wheel rim.
