I'm looking at maybe doubling up 9mm belts, but you could also try 15mm or something thinner. You're looking at $20-$100 per tread depending on width and length of the belt.

Here's a nice tool for sizing belts and pulleys: B&B Manufacturing Belt Calculator

That's a nice one. My favorite is the SDP-SI one. Just another option.

Re: [FTC]: Tank Treads

My team has had poor experience with tank treads in the past. We've had issues with the treads coming apart or slipping off the wheels and pulleys due to contact from the side, resulting in a torquing motion.

Just to serve as word of caution, speaking from experience. They tend to be a hassle and result in a lot of pinched fingers.

I found some interesting videos for various climbing robots with treads and wheel designs:
