In this study, the shape evaluation and design of the spare tire carrier for SUV (sports utility vehicle) were addressed through structural analysis. Spare Tire Carrier analysis was conducted to evaluate rigidity, and strength and improvement measures for appropriate shapes were found and reflected in the design. Through structural analysis of the spare tire carrier, this study was conducted to derive an optimal design plan as the stiffness and strength needed to be increased for stable installation of the spare tire carrier. Compared to the existing model, the bar, which was curved, was changed to a straight line to shorten the length, thereby increasing rigidity. In addition, because the moment was concentrated in the structure of the rear hanger mounting bracket, the side part of the bracket was extended, but the cross member stiffness was relatively weak, so it did not have a significant effect.
