You’re not sure if you hit a nail or ran through glass. What you do know it that your tire is definitely flat. It could be repaired at the mechanic’s shop or you could save yourself the trip and expense and do it yourself. The process can be a little time consuming, but once you know how to repair a flat you will never again be at the mercy of closed shops or stuck in the middle of nowhere. Taking the time to learn this essential maintenance process now will save a lot of time and hassle later.
The first thing you need to do is determine where the puncture is located. A quick way to do this is to submerge the tire in water and watch where air bubbles form. Obviously this area or areas are the place you need to concentrate on. Before the patch job can begin it is important to remove any foreign object that is stuck there. Pliers are a good tool for this step. Simply use the pliers to pull the object out in the same direction as the tire’s tread. Being sure to go with the tread helps ensure that minimal additional damage is done to the tire.
Now is the time to prepare to patch the tire hole. Using a tire reamer clean the hole out from the inside of the tire. This will remove any dirt or oil that may later cause adhesion issues with the cement and patch. Place the patch centered over the puncture to be sure sizing is correct. Remove the patch and coat an awl with cement. Be sure to run the awl through the hole several times to be sure the cement is coating the damaged area adequately. Place a coat of vulcanizing cement on the patch and buffed area of the tire and allow to dry thoroughly.
Remember the awl is still through the hole. Apply a thin layer of cement to the stem of the patch and pull the stem through the hole. Once the patch stem is through the puncture cut the stem off almost flush with the outside of the tire’s tread. The tire is now patched and there are a just a few more things to do before you are back on the road.
To finish up the tire repair job and to help make sure your tire problems are a thing of the past, take the time to complete a few preventative measures. One useful precaution is to take a look at your valve stems. If they look worn, old, or damaged it is a good idea to change them. Be sure they are the right length and diameter for your car’s tires.
Valve stems are important because not only do they function to retain valve core air retention, but they also keep moisture and dirt from getting inside the tire. Once you are assured that the valve stems are in good condition reinflate the tire. Using soapy water sprayed on the tire is useful to see if there are any leaks in the new patch, around valve stems, or the beads.
Having a flat tire is certainly an inconvenience, but some time and a little patience can have you back on the road with safe, road worthy tires.
