Should I Replace or Repair a Car Tire Punctured by a Nail?

[JaceRose]

If a car tire is punctured by a nail, whether to repair or replace it depends on the location and extent of the damage. Here are the details: 1. If the puncture hole exceeds 6mm in diameter: the tire needs to be replaced. 2. If the puncture is in the tread (crown) and the nail is relatively thin: it can be repaired at a professional repair shop. The best repair method is using a mushroom plug, which involves inserting a mushroom-shaped rubber strip from the inside to the outside of the tire to completely seal the puncture. The excess part outside is then trimmed off, and the inside part is secured with special adhesive. This method not only provides an external fix but also effectively repairs the tire internally. 3. If the puncture is in the sidewall: it's best to replace the tire. The sidewall is the weakest part of the tire and undergoes constant deformation and recovery during rotation. Forcing a repair can cause the adhesive patch to detach, and even using a hot patch method would only be a temporary solution.
