Can a Nail in the Sidewall of a Tire Be Repaired?

[Fonseca]

Whether a nail in the sidewall of a tire can be repaired depends on the following factors: 1. The decision to repair or replace the tire is based on the location and extent of the damage. If the nail punctures the tread (crown) and isn't too thick, it can usually be repaired professionally at a repair shop. The most effective repair method is using a mushroom plug, though this option is more expensive. However, if the nail punctures the sidewall of the tire, it cannot be repaired and must be replaced. 2. Apart from sidewall punctures, the following situations also require tire replacement: tread puncture holes larger than 6mm in diameter, deformed bead or tread, corroded rubber, tire damage due to running flat, or if the tire has been patched more than 4 times.
