Causes: tyres have been punched, bad repair,valve cock rubber aging,the valve core is not reset after checking the air pressure etc.All the above circumstances will lead to tyre flat,lack of air pressure.
Driving with low pressure will lead to tyre excessive buckling,this will make tyre produce high heat.The inner airtight layer of rubber will be burned into black spots, and then rubber and tyre cord fabrics separate. More seriously, the air tightness rubber will be burned by high heat, producing melting. So the internal structure of the tyre will be damaged severely . If the tyre continues under the condition of lower strength, it will eventually lead to tyre burst.
