Should a Nail-Punctured Tire Be Repaired or Replaced?

[StFrancisco]

Tire puncture caused by a nail can be either repaired or replaced depending on the extent of damage. Here are the solutions for a punctured tire: 1. Tire Repair: When the puncture hole on the tread is only 6mm, tire repair is an option. Since a nail puncture does not severely damage the tire's structure—only piercing through the steel belts, fabric layers, and polyester layers—repairing it is sufficient. However, for enhanced safety, it's advisable to replace the tire and use the damaged one as a spare. 2. Tire Replacement: If the tread is deformed or the tire body is severely damaged, the tire must be replaced. Tread deformation is actually caused by damage to the tire body. When the tire body undergoes significant stress, its internal structure is compromised, leading to deformation. At this point, the tread also deforms, indicating the end of the tire's lifespan.
