WARNING: This page is about a different car, the 2022 Volkswagen ID.4 and 2021 Volkswagen ID.4. 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.

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:

Damaged tire bead core.

No secure fit for the tire on the rim.

- Replace the tire.
