How do I add custom wheels?

I want to learn how. The MultiDae tutorial is outdated.

Under suspension, there should be wheel hubs within that there are brakes and wheels. Click wheels and there should be a list that comes up with all the different wheels in the game

*facepalm* I meant how to make my own custom wheels that I add.
