Radial crack in rim flange |
P40.10-5748-04
As part of warranty findings we have established that light alloy wheels with radial cracks are being replaced under warranty.
This damage is attributable to events such as driving over an obstacle, punctures etc. and is therefore not relevant to warranty (see Radial crack in rim flange).
Low section tires are being used increasingly. In the process both the tire and rim are significantly more sensitive to mechanical damage due to the lower sidewall height particularly in combination with too low tire pressure.
In the event of a puncture (e.g. while driving over corresponding obstacles) the rim flange is possibly deformed plastically or pre-damaged so that either a radial crack occurs immediately or only occurs later due to the operating load.
In the case of the damage mentioned it is not a material fault although this is mistakenly assumed. The damage mentioned is not to be attended to by the manufacturer but is clearly attributable to external influences.
For safety reasons we recommend replacing the tire as well in the event of a puncture. It cannot be ruled out that the tire has suffered internal pre-damage of the fabric (carcass).
