RESISTANCE TO PUNCTURES:
There are 3 types of punctures
1) PINCH SHOCK – the tube and tire are pinched between the rim flange and the ground when
rolling quickly over an obstacle, (a pothole, for example). The impact
resistance pinching is obtained by the tire's volume, the thickness of the
sidewall, and the thickness of the tube. Adapting inflation pressure avoids
this type of puncture mostly.
2) PERFORATIONS AND CUTS – nails, stones, thorns, and fragments of glass can all cause perforation. The
aggressiveness of the components of certain surfaces can also generate cuts.
The thickness and the quality of the tread rubber, the density of threads in
the casing, the presence of a textile or rubber reinforcement (puncture
protectors) are all elements which dictate the resistance of tires to these
types of punctures.
3) PERFORATION BY THE RIM BAND – It occurs when the rim band/tape is unsuited (width, material, etc....) to the
rim or in bad condition. This type of perforation is identified by its position
inside the rim on the tube. To avoid this type of puncture, we recommend
changing the rim band every time you replace the tire or tube.
