Condition of damage

   Normally, the tyre sidewall is severely damaged as in the picture shown on the right. In the case of bias tyres(cross-ply tires), the inner carcass cords may separate and may be exposed on             the surface

Causes       

• 1. Continuous running after puncture
• 2. Excessive underinflation(close to a flat condition)

Recommendations

• Stop to use the damaged tyre
• 1. Stop the vehicles as soon as a flat tire is aware of, and change the flat tire to spare tire immediately
• 2. Check air pressure frequently
• 3. Check any nails imbedded in tread or other external damage frequently
