How to Reseal a Flat Tubeless Tire

What You'll Need
Tire glue
Tire patch
Air Pressure Pump

A tubeless tire can be a big problem when it becomes a flat tire. The tubeless tire is very popular due to its hard-wearing toughness, but it can be a serious pain if you happen to pierce it. Tubeless tires have been shown to be much less likely to deflate than a tire with an inner tube, and you are also saved the effort of having to extract that inner tube, which often involves a kind of wrestling match with the beast. However, if your tubeless tire has been punctured, it will slowly deflate until you are forced to repair it. In order to reseal a tubeless tire, you will need some tire glue and perhaps patch.

Step 1 - Remove the Tire

You can extract the tire whole from the wheel by simply popping it out of place. You must deflate the tire completely by opening the valve. Once the tire is completely flat, push the tire into the middle of the rim, and then roll it away from the wheel.

Step 2 - Find the Hole 

Lay the tire down on the ground, and locate where the air is leaking from. You may be able to spot an obvious hole in the tire, but if the hole is invisible, you can use an air pressure pump to force in air until you can see where the damage has been done.

Another alternative is to slightly fill the tire with air, and then put it into a basin of soapy water. Look for bubbles to locate the leak.

Step 3 - Apply Tire Glue

Once you have located the hole, clean around it using a towel and some soap. Leave this to dry, and then apply tire glue to the hole.

If the hole is large, then you will have to insert a tire patch over the hole, and then glue around this, sealing the patch to the tire, and preventing air escape. Do this by adding a layer of sealant, and then leaving to sun-dry. Take care not to sand down any part of the tire, but instead add a little bit of glue, and then push the patch onto the top.

Step 4 - Finishing Up

Leave the tire to completely dry, until the glue has become sufficiently dry not to detach from the hole when touched with a finger. Apply a layer of sealant over the top, and leave this to dry naturally. When the hole has been repaired, put the tire back on to the rim, moving the wheel so that the repaired area is at the top. Press the wheel back into the rim, going slowly around the whole wheel. When it has been completely inserted, use a pump to re-inflate the tire, and leave the wheel to settle into place.
