The trouble with the Brecoflex belts as ordinary wheel tread is that they'll be an order of magnitude more expensive than strips of conventional conveyor belting. Other than that, they ought to work fine.

A belt sander should be able to take the ridges off cleanly. But at that point, you're basically just turning them into ordinary belts. (Not worth it!) Just see if you can find the tread facing materials elsewhere, or ask them about supplying that alone or on a custom thin, flat belt.
