We ran 9mm wide GT2 belts last year, and didn't have any ratcheting. We had some wear, but it was what you would expect for a device running outside the rated specifications. 1 set of belts lasted the entire season (2 competitions, 1 offseason, and lots of practice.) Ratcheting occurs when your belts are under-tensioned, which means that your belts were under tensioned. You can look at the failed belt to figure out what was wrong. For comparison, we had a 24 tooth pulley with a 3.5" diameter wheel.
