Abstract

In Indonesia, the acceleration of electric vehicle development has been supported by the government through Presidential Regulation of the Republic of Indonesia Number 55 of 2019 concerning the Acceleration of the Battery Electric Vehicle Program. Airless tires, also known as non-pneumatic tires, do not require pressurized air as conventional tires do. Several reasons support the use of airless tires as a substitute for conventional ones, such as the absence of the need for run-flat technology, the elimination of air pressure requirements, and their generally lower rolling resistance compared to traditional tires. One of the factors that can influence the performance of airless tires is infill density. This highlights the need for a deeper understanding of how variations in infill density can be optimized to reduce vibration and improve riding comfort under various road conditions and different vehicle applications. In this study, infill density is varied as an alternative to air pressure in the tire structure. The infill density variations used are 20%, 40%, 60%, and 80%. The use of airless tires with infill densities of 40%, 60%, and 80% tends to increase the RMS value, indicating that the vibrations transmitted to the bicycle also become greater. The corresponding levels of riding comfort obtained for each variation are categorized as uncomfortable, uncomfortable, and very uncomfortable.
