Punctures






CAUTION: Tire sealants that are injected Through the valve stem are not to be used to service punctured tires because they can produce wheel rust and cause tire unbalance.

^ Punctured tires should be removed from the wheel and permanently serviced from the inside using a combination service plug and vulcanized patch. When servicing a puncture, always follow the manufacturer's instructions for using the service kit.
^ Service punctures that are in the tread area only. Never attempt to service punctures in the tire shoulders or sidewalls. In addition, do not service any tire that has sustained the following damage:
- Bulges or blisters.
- Ply separation.
- Broken or cracked beads.
- Cracks or cuts.
- Tires worn to the fabric, or if the wear indicators are visible.
- Punctures larger than 6.35mm (1/4 inch).
