Tyre Damage
| Symptom | Description |
|---|---|
| Age Deterioration | Cracking and crazing of the tread and sidewall rubber, sometimes accompanied by carcass deformation. An indication that the tyres have been in service for a very long time. |
| Neglected Cut | Damage through accidental cuts or penetrations will extend in use due to continued flexing and / or ingress of moisture and road matter. |
| Impact Fracture | Resultant damage from impact fractures is not always visible externally and, therefore, as a safety precaution the tyre should be removed and examined. |
| Casing fracture caused by severe localized impact through driving over kerbs, hitting potholes and / or objects in the road. | |
| A double fracture caused by crushing the side wall of the tyre between an object and the rim flange. In both instances, such damage can lead to sudden and dangerous tyre deflation some time after the impact occurred. |
