These wheels were made back in the hay day before BeamNG.Drive was released and I figured instead of them never seeing the light of day I'd upload them here for anyone to enjoy.
I designed them to fit the Burnside and my Kumho ECSTA SPT tires to fit them. The zip contains the sizes (in inches): 18x12, 17x12, 16x12, 15x15.5. They are the final version I will be releasing as I do not have time to test and modify them anymore.
The thread for my parts is located here.
