Should You Patch or Replace a Punctured Tire?

[DiMadison]

Here is an introduction to the situations for patching and replacing tires: 1. Patching a tire: (1) When the puncture on the tread is only 6mm, you can choose to patch the tire. This is because a nail piercing the tire does not significantly damage the tire's structure—the steel wires, cord fabric, and polyester layers just have a hole that can be repaired. Of course, a safer approach is to replace it and use the damaged tire as a spare. (2) Minor tread cracks can also be repaired. Road conditions in many regions are complex, with uneven surfaces and debris, leading to frequent tread damage. Minor tread damage can be repaired to extend the tire's lifespan. If the tread pattern is peeling off, repair may not help, but if it's not severe, the tire can still be used. However, for high-speed driving or for owners who can afford it, replacement is recommended to ensure driving safety. 2. Replacing a tire: 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 is subjected to significant force, its internal structure is compromised, leading to deformation, and the tread follows suit. At this point, the tire's lifespan has effectively ended.
