Radial Crack in Light Alloy Disk Wheel
Through inspection of returned warranty parts, it has become evident that light alloy disk wheels are being replaced under warranty for radial cracks.
This type of damage is attributable to driving over obstacles and resulting punctures. The rim flange becomes deformed and a radial crack occurs
immediately or later due to the vehicle's operating load. This type of damage is not covered under warranty.
Low section tires also significantly contribute to mechanical damage because of their lower side wall height and the possibility of a crack can be
exacerbated by low tire inflation pressure.
For safety reasons, a tire should be replaced after it has been punctured to preclude internal fabric damage of the tire carcass.
