Step 1: find the position of the puncture and pull out the foreign body of the puncture.

Step 2: insert a tapered file into the puncture hole of the car, and the number of times will be drawn back and forth. The purpose is to make the surface of the hole to file out the stubble, so that the adhesive can be closely combined after the adhesive tape is inserted.

Step 3: take out the tape, put it into the eye of the taper, and make the tape on both ends of the cone equal length, and then make a single strand of the tape at each end.

Step 4: led strip with the awl its slowly inserted into a slot in the tire, the depth of the insert to enter the fetal strip can have five centimeters in length, at the same time ensure that show outside the tire strip it is advisable to not less than 1 cm.The problem with this step is that you can actually get the tape into the tire when you insert it.

Step 5: pull the taper out of the tire.Pull out slowly, so as to ensure that you can pull out the cone and bring out two more.When the fourth step was completed, two strips were inserted into the punctures of the tyre.After pulling out the cone, there should be four strands in the punctures.Two strips of adhesive tape will not have to come out of the tube, but make sure they are squeezed into the pierced hole.This step is very important.Frequently met in this step has two kinds: one is pulled up when the awl strip has not been out of the two, by making holes in the strip or two, there is no guarantee that the hole is tight strip block;The second is to pull out the taper and force the rubber strip out of the tire, causing the tyre to fail.

Step 6: give the car full air and use saliva to smear around the tape to check for air leakage.If there is a leak, the replacement is a failure.If there is no leak, it is a success.

Step 7: use a razor blade to strip off the tape of the outer part of the tire and make the outer surface of the tire smooth.
