If we consider two identical tires, one may last three times as long as the other, depending on the user and the terrain.
This service life depends on:
- The thickness of rubber at the crown
- The resistance of the rubber compound to wear
- The resistance of the casing to "fatigue"
- The tire's resistance to attack (ozone, crazing, cuts, UV rays,...)
- The pressure match between the cyclist and the type of use
