Tire Repair Tool
1. Jack up the car and try to locate the puncture. If it is difficult, please infuse some "sealer and inflator foam" into the tire. Pull out the sharp object after marking the puncture.
2. Insert the tire reamer counterclockwise into the puncture to shape the puncture. Withdraw the reamer clockwise and reinsert to shape the puncture once more. Then let the reamer stay in the tire (this is to facilitate the insertion of the string).
3. Insert one string (or two for large punctures) into eye of the tire needle, make the string with equal length on both sides of the needle. Withdraw the tire reamer and insert the needle with string into the tire with force till about 1cm of the string remaining outside. Then slowly withdraw the tire needle.
4. Cut off the excess string with the tire tread. Then use the "tire sealer and inflator foam" to inflate the tire.
