Repairing a Tire
If your tire becomes damaged, it may be repaired if it meets the following criteria:
- The tire must not be driven on when flat
- The damage must be only on the tread section of your tire (sidewall damage ruins a tire immediately)
- The puncture must be less than ΒΌ"
- 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
Patch, Yes. Plug, No.
The proper way to have a tire repaired is to patch the tire from the inside and fill the puncture hole. Do not have your tire plugged. Ever. Plug repairs do not involve taking the tire off the wheel for a proper inspection. A plug is simply inserted into the punctured area, making it unreliable. Insist on a full inspection and have your dealer demount and internally as well as externally inspect the tire, patch and fill the repair on the inside of the tire.
