You can’t ignore tread punctures or penetrations because they can cause irreversible tire damage. At the same time, an improper repair can damage the tire and void a tire’s warranty. Only punctures in the tread area less than ¼” in diameter may be potentially repaired and returned to service. Consult your tire repair professional to determine if a tire is repairable and always have a professional perform the repair.
If any of the following conditions exist, the tire cannot be repaired:
- A tire worn below 2/32" (1.6 mm)
- Tires with tread punctures larger than 1/4" (6.35 mm)
- Holes larger than 1/4" (6.35 mm)
- Sidewall or shoulder damage
- Broken or deformed bead wires
- Deterioration of rubber
- Damage to the bead
Plug and Patch is the Proper Tire Repair
While plug or patch repairs are common, using plugs or patches alone is not considered a proper repair. The combination of a plug and patch is the correct and proper method.
