When is a tire worn out?
When the puncture protection belt or the carcass threads can be seen through the tread the tire has reached its wear limit and must be replaced. As puncture resistance also depends on the thickness of the tread layer, it may be useful to replace the tire sooner.
The sidewalls of tires often fail before the tread is worn out. In most cases, this premature wear is due to prolonged use of the tire with insufficient pressure. Checking and re-pumping the inflation pressure at least once a month with a pressure gauge is most important.
For tires with a deep tread pattern that generate grip in loose terrain, like those used on a mountain bike, a worn out tire can lead to loss of grip and safety concerns.
In such instances the user may wish to replace their tire even before the puncture protection belt or carcass threads begin to appear.
