Volkswagen Polo Service & Repair Manual: Mounting Damage
| Bundle broken during tire inflation. |
|
|
|
| Modern radial car tires are mounted only on safety rims.
These have a hump -1- running along
the shoulders. |
| The hump prevents the tire from being pressed out of the
bead seat during travel with insufficient tire pressure. |
| When the tire is inflated, the tire bead may not slip
completely over the outer rim hump. |
| In this case, there is the danger that the bead bundle will
be overstretched if the tire pressure is too high and the steel
wires rupture partially or completely. Torn bundles are often
not detectable from outside. |
DANGER!
| Tires with damaged bead bundles are not seated
safely and securely on the rim. Such tires are a safety
risk! |
| In addition, there is the danger that a partially
broken bundle tears during continued operation and the
tire suddenly tears open. If the bead bundle breaks
during inflation, the carcass will also be destroyed. |
