What pullies are you running, specifically tooth count? 6" wheels complicates the matter even more, as the load in the belt is higher than with a smaller diameter wheel. Also will you have a means for tensioning or are you setting it up for exact center to center distance?

The failures we experienced were mostly ratcheting, teeth skipping as we changed direction rapidly. This of course accelerates wear and leads to failure quicker than normal. That said, we never had a belt totally fail, although we replaced belts every regional.
