Knowing the difference between a proper tire repair and an improper tire repair could be critical to vehicle safety. A tire industry study showed that nearly 88 percent of the tire repairs are performed improperly. An improper tire repair could pose a safety hazard to you and your family and could also affect a tire manufacturer’s warranty.
One key process in a proper tire repair is removing a tire from the wheel to inspect any damage that may occur to the inner liner of the tire.
- Repairs are limited to the tread area only
- Puncture injury cannot be greater than 1/4 inch (6mm) in diameter
- Repairs must be performed by removing the tire from the rim/wheel assembly to perform a complete inspection to assess all damage that may be present
- Repairs cannot overlap
- A rubber stem, or plug, must be applied to fill the puncture injury and a patch must be applied to seal the inner liner. A common repair unit is a one-piece unit with a stem and patch portion. A plug by itself is an unacceptable repair
Below you will find a number of resources that can help understand the proper puncture repair procedures for your tires.
