Mounting Damage
WARNING: This page does not describe the selected car, but rather 18 other vehicles, including the 2016 Audi S4, 2016 Audi A4 Quattro, 2016 Audi A4, 2015 Audi S4, and 2015 Audi A4 Quattro. However, it is still accessible from the selected car via links, so may be relevant.
Bundle broken during tire inflation.
Modern radial car tires are mounted only on safety rims. These have a hump -1- running along the shoulders.
1 - Hump (H2)
2 - Inner bead seat
3 - Rim
4 - Wheel disc
5 - Outer bead seat
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.
CAUTION:
- 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.
