Hi Sudeep, this was not meant as a tutorial; Shawn had asked me during the stream to show how I made the number of treads changeable, so I just showed my workflow here.
Don’t worry about not understanding the Driver part, that is completely unnecessary in tire making, that was just me, seeing if I could pull it off;)
Drivers are not something I can explain in a few words, unfortunately.
Maybe have a look at the Manual: https://docs.blender.org/manual/en/dev/animation/drivers/introduction.html?highlight=drivers
