Do not use the worn or "wound" tires: replace wound tires ASAP

Do not use the wound tires, especially the side holes on them. Due to complicated road conditions, we sometimes encounter the puncture of tires. If the puncture occurs on the front side of tires, if the puncture happens on the tread of tires, tires can be fixed by patching or plugging. But if the holes or puncture happen on side of tires, please do not use the tries anymore. It would make you and your car at high risk.
Drivers should do the daily check on the tires. If you find any cuts, or nails on tires, tires should be repaired or replaced immediately. Also if any small stones are stuck between treads of tires, these small things should be removed from tires to avoid any further damage to tires, or it would make tires deformed gradually. Another thing, keep the tires away from any oil and chemicals.
Periodic rotation of tires is necessary for the tires safety. Also it would equalize the wear among the tires and prolong the tires life. The tires rotation should be taken every 5,000 kms, and four wheels alignment every 5,000 kms to 10,000 KMs. Do not use on same axel the tires of different brands or, one is too new tire and the other too old tire. Four uneven tire wear would lead to the severe shakes during the speed driving. If it’s too uneven among the four tires, it would cause the severe vibration during the high speed driving, which would be very dangerous.
