Today, most of the cars are running on tubeless tyres, and many years of development in tyre industry have reduced the occurance of flat tyres. But they can still happen in the middle of nowhere and for some reason if you don't have your spare tyre or if you have puncture in more than one tyre then, there are not many options left for you. For situation like this, we must always have puncture repair kit and portable pump in our car. However, just keeping it is not enough, we must also know how to use the puncture repair kit. Puncture repair kit could be brought from any tyre store. It usually comprises of strips of puncture inserts, spiral tool, inserting tool, rubber solution tube and a small blade.
Here is a step by step guide on how to fix a pucture on a tubeless tyre-
Make sure that the tyre is actually punctured. In some cases, air loss is also caused by problem with valve stem on the wheel. It might have a small crack on the outside, but sometimes the inside mechanisim can also malfunction. To reduce the chances of tyre valve mechanism failure, valve caps should always be present to cover the valve and stop accumulation of dirt inside the valve.
After inspecting, if you find that the tyre is actually punctured, then remove the tyre from the vehicle.
Inflate the tyre and look for any nails or spot from where the air is leaking. Inspect visually and also notice if you can hear the hissing sound from the leaking spot. If you are still not able to find the spot, then use a soapy solution, wet the tyre and look for bubbles.
Now, after finding the affected area, pull out the nail or any other foreign material that has punctured the tyre. Make sure you note the angle of the nail when you pull it out.
Use the spiral tool from the repair kit and drive it into the puncture hole, rotating it clockwise simultaneously. The angle in which you insert the tool should match the path of nail that was pulled out previously.
Take one puncture strip and feed it half way through the inserting tool. It's like threading a needle. It's fine when the strip is halfway through the tool.
Now, take the rubber solution and apply a little bit on the strip. The user should put this rubber solution before inserting the strip into the hole in the tyre.
Take out the spiral tool from the tyre and insert the strip inserting tool into the hole. Make sure to stop when about 2 cm of the strip is left outside. Now, pull out the tool. Due to the slit present on the tool, the strip will easily slip out of it.
Cut off the extra part of the strip sticking out of the tyre and check if the repair is good by wetting the area with soap solution.
