see, i disagree with that. Unless the belt is stretching, it cannot get "looser". Slack in the belt can move to different areas, but to actually get "looser" would be impossible, unless you take in account heat expansion... and stretching when the belt it new...
The belt on the XXXS is pretty tough. If you have ever held one out of the car, and pulled.. they really have a lot of stregnth.
