| - Cuts in curtain with bubbles | Considering damages of bubbles, blowouts |
| - Cuts in curtain towards the perimeter | No change |
| - Partical cut in steal belt or the belt exiting away tire hoop, but it does not lose pressure, has no mark of patched, no change in shape of tire and there is no trace inside tire, no more than 2 patches | Change if warrany bar is still available |
