Tire sizes for light vehicles include all passenger car tires and some light truck tire sizes (through Load Range E). Light vehicles are motor vehicles with a gross vehicle weight rating (GVWR) of 10,000 lbs or less.
- Not all tires can be repaired. Specific repair limits should be based on recommendations or repair policy of the tire manufacturer and/or type of tire service (e.g., service description, run-flat technology, commercial service applications, etc.).
- For all tires, repair units cannot overlap. The number of repairs should be limited first by the tire manufacturer’s recommendations and repair policy and then by application and the individual tire’s condition as determined by an external and internal inspection.
- Some run-flat technology tires cannot be repaired. Consult the tire manufacturer for its repair policy and, if applicable, for its recommended repair procedures.
- Follow Industry recommended repair methods. These include: (1) Two-piece stem and patch repair components, and (2) one-piece patch/stem combination repair units. For punctures angled greater than 25 degrees, two-piece stem and patch repair components are recommended. Never use only a plug (stem) or never use only a patch to repair a puncture.
