A wheel assembly is basically a sub-assembly of the suspension system that would link the tires to the chassis through the double wishbone A-arms provide a mounting point for the tires and act as the load bearing component at the wheels. A wheel assembly comprises of the upright, hub, wheel center and lugs. The major difference between the mono-lug wheel assembly and the tri-lug or quad-lug wheel assembly is the number of lug bolts and nuts that are used for a secure mounting of the tires. The main aim of this thesis is to provide the proper calculations and design analysis for a compliance free monolug wheel assembly while comparing it to a traditional trilug wheel assembly. The weight of this monolug assembly is 977.5 which correspond to a direct 12% reduction of weight when compared to traditional trilug assembly which weighs in at 1112.59g as found from the previous wheel assembly designs of our formula student vehicle assemblies. The following mono-lug wheel assembly is being used in DJS Racing's electric vehicle for the 2020 season, DJSR E02. All calculations done in this thesis are in co-ordination with the rules laid out in the FSG 2020 rulebook
