Tread Help

[orangeandblack5]

We have a tread-ready chassis along with our current wheeled chassis, but our coach purchased a timing belt (from V-Belt Supply) and the actual tread material (from AndyMark) separately. How do we attach these? We don't want to ruin them, as (for whatever reason) we didn't buy any extra of either part, and using glue just doesn't seem like it would be a good idea unless we know it will work. So, how do we attach these parts securely whilst keeping flexibility?

(Any other tread-related tips are also appreciated, as we're a second-year team and really want to do this right, because the 8-inch wheels on our current chassis are less than ideal.)
