How to Reseal a Flat Tubeless Tire

It's important to know how to properly reseal a flat tubeless tire in case you get a puncture in a tire while out on a trail or away from a maintenance center. Having a tubeless tire means you will not have to worry about replacing tire tubes, but it does mean that you need to take extra care in sealing your tire properly in order to prevent future leaks from a reseal spot on the tire.

      Locate the punctured or torn area on your tire. Clean off chunks of dirt and grass from the tire to be sure to find the area where air is leaking from the tire. Mark the punctured space on the outside of the tire with a marker so you can find it easily.

      Grab and squeeze the tire to relieve air pressure that presses the tire to the rim. Place the lip of a tire lever under the tire and run the lever around the perimeter of the tire to gradually work the tire away from the rim. After a few times around the rim you should be able to completely remove one side the tire from the rim. Now you can access the underside of the tire to reseal the puncture or tear.

      Clean the spot of the tire puncture with a paper towel on the inside of the tire. Blot the tire sealant on the area of the puncture until the hole or tear is completely covered by the sealant. Allow the sealant to dry completely by letting it sit in a sunny, dry area.
