Plugging a Tubeless Puncture

Tubeless tires seal most small holes by themselves, but not all, and the fix for the rest is quick once you have done it. First spin the wheel so the hole sits at the bottom and give the sealant a chance to work. If it keeps hissing, push a sticky rubber plug, often called a bacon strip, into the hole with the fork-shaped tool, then ease the tool out so the plug stays behind. Trim any long tail, not flush, and reinflate. Leave the repair at the bottom of the wheel for a few minutes so sealant can flow into it. A large cut may need more than a plug. Carry an inner tube as the last resort, knowing that fitting it into a tire full of sealant is a messy job, and check the sealant at home afterwards, since dried-out sealant needs refreshing.
