I want to tell you what you should when in emergency situations. Before you actually start repairing tubeless tyre puncture, you must have these things stored in your car, basically, tire tools, tire repair tools, tire changer tools and so on.
1 – First, properly inflate the tyres and locate the puncture(s) by checking for any sharp objects that might have caused the puncture. Because there are times when the case is not exactly of puncture rather of air leaked out of the tyres.
2 – If you find that there is some sharp object (nail, pin, thorn, etc.) then carefully remove it with the help of pliers. If any object (no matter even small) is left behind inside the tyre, it will surely puncture it again in some time.
3 – Now take the spiral tool and push it into the puncture in the clockwise direction. This will make it easier to insert the puncture strip.
4 – Now remove the seal from the puncture strip and push it through the inserting tool like you do with a needle and thread.
