Volkswagen Polo Service & Repair Manual: Mounting Damage

Volkswagen Polo Service & Repair Manual / Whels, Tires, Whel Alignment / Tires, Evaluating / 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.

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.

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.
