: Since friction is relatively independent of surface area, it appears tank treads would not buy you much in this competition.

I'm not so sure I agree. If friction is independent of surface area then why do drag cars have really wide tires and how can a tank brake from 60-0 on pavement faster than most sports cars. In my experience friction is a fickle thing that really needs experimentation to understand it well.

In my experience the way to generate lots of traction on carpet without damaging it, is to contact lots of carpet. Using double sided timing belt on a tank tread is one way to do this, albeight a difficult one though.

Tall skinny tires are good for swamp racers and snow tires because they dig through the soft top and get down to the hard bottom. This method would seem to be a little more likely to damage carpet to me.

Good luck!
