Repairing tyres with run-flat capability (PAX)
General information
It is not always necessary to renew a tyre after it has lost pressure and then been run in an uninflated condition.
  Note
The affected tyre should be removed and checked for damage by qualified personnel. Fitting of tyres and checking tyres for damage must only be carried out by qualified personnel.
After a run-flat tyre (PAX) has lost inflation pressure, check the tyre as follows:
–  First remove as much gel residue from the tyre as possible. Use the flat side of the putty knife to do so.
–  Then clean away any remaining gel residue from the tyre and support ring using water and a cloth.
–  After separating the tyre and support ring, check both components (PAX) according to the following criteria.
Notes:
–  When re-installing, make sure the support ring is the correct size for the tyre and wheel dimensions.
–  As with standard tyre/wheel systems, the PAX wheel must also be checked before fitting.
–  Damaged wheels must be renewed.
