| Bead damage caused by fitting machine |
| The following errors which can be made when fitting tyres can lead to severe tyre damage: |
| t
| When rolling the upper bead on the tyre fitting machine, the opposite tyre bead is not seated completely in the rim well. |
| t
| The fitting head was not adjusted correctly. |
| t
| The edge of the fitting roller rolls onto the bead. |
| t
| The guide rollers are worn or have sharp edges. |
| It is often possible to identify the tracks of the guide roller as it was applied or ran off where the damage occurred. |
Note | Both tyre beads as well as the bead seats must always be coated with assembly paste. |
| If fitting damage remains undetected, there is a danger that the tyre will fail later during operation. |
| l
| Never fit a tyre without using assembly paste. |
| l
| Do not allow the bead seating pressure to exceed 3 bar. |
| l
| Do not allow the tyre inflation pressure to exceed 4 bar. |
| l
| When the tyre has been fitted, reduce the tyre pressure to the specified value. |
