Do I Need to Replace a Tire with Two Nails in It?

[VonHolden]

Here is an introduction regarding whether a punctured tire needs to be replaced: 1. If the puncture hole on the tread is only 6mm: For economic considerations, it can simply be patched and continue to be used without replacement. This is because a nail puncture does not significantly damage the tire's structure—it merely creates a hole in the steel belts, fabric layers, and polyester layers, which can be repaired. However, for greater safety, you may choose to replace it and use the damaged tire as a spare. 2. Slight tread damage: Repairable. Road conditions in many areas are complex, with uneven surfaces and debris, making tread damage common. Minor tread damage can be repaired to extend the tire's lifespan. If the tread pattern is peeling, repair may not be effective, but the tire can still be used if the damage is not severe. However, for high-speed driving or for owners who prioritize safety, replacement is recommended. 3. Severe tread or carcass damage: The tire must be replaced. Tread deformation is often caused by damage to the carcass. When the carcass is subjected to significant force, its internal structure is compromised, leading to deformation and ultimately rendering the tire unusable. If the tread comes into contact with sharp objects, causing severe tread loss or carcass cuts, or if the puncture hole exceeds 6mm, repair is no longer viable. In such cases, the punctured tire must be replaced to ensure driving safety.
