Does a Nail Puncture Require Tire Replacement?

Generally, a nail puncture does not necessitate tire replacement. If the nail has not penetrated the sidewall but only the tread, and hasn't fully punctured the tire, the nail can simply be removed—though this should be assessed by a professional, and it's advisable for car owners not to remove the nail themselves. If the nail has fully punctured the tire, a repair is needed. Below are details regarding nail punctures in tires: 1. Puncture Depth: When the tread puncture is only 6mm, for cost-effectiveness, a simple patch repair is sufficient, and the tire can continue to be used without replacement. This is because a nail insertion does not severely damage the tire's structure—the steel belts, fabric layers, and polyester layers merely sustain a small hole that can be patched. Of course, replacing the tire is safer, with the damaged tire then serving as a spare. 2. Minor Tread Damage: Repairs are possible. Given China's complex road conditions—uneven surfaces and frequent debris—tread damage is common. Minor tread damage can be repaired to extend the tire's lifespan. If the tread pattern is peeling, repairs may not help, but the tire can still be used if the damage isn't severe. However, for high-speed driving or for owners who prioritize safety, replacement is recommended. 3. Severe Tread Deformation or Carcass Damage: Replacement is mandatory. Tread deformation often results from carcass damage. When the carcass undergoes significant stress, its internal structure is compromised, leading to deformation and rendering the tire unusable.
