Our advices and commitments

Mounting instructions

1- Installation is done when fitting the tyre.
2- Rest the tyre flat on a table.
3- Mount the inner tube by starting with the valve. Carefully inflate until it falls into place.
4- Slide the Z Liner between the inner tube and the tyre.
5- Roll out the Z Liner and insert it opposite the valve.
6- Cut the tape with a pair of scissors being careful to leave a 2 cm gap between the two strips which will help stop the tapes overlapping and pinching the inner tube. A squashed inner tube is more likely to puncture.
7- Check the Z Liner is in the correct position before adding the rest of the tyre and inflating it to the right pressure.
