Can a Puncture on the Sidewall of a Tubeless Tire Be Repaired?

[Daniela]

Tubeless tire sidewall punctures can be repaired. The repair method is as follows: 1. Remove the Wheel: Take off the wheel and remove the tire. When removing the tire, it's best to use a bamboo stick to pry one side first, then press both sides of the tire toward the middle to gently remove it, being careful not to damage the edges of the tire. 2. Clean the Debris: After cleaning any debris from the puncture, use sandpaper inside the tire to roughen the area around the puncture, apply cold patch glue (you can apply more, but only once), wait 5-7 minutes, then apply a large cold patch inside the tire. For higher speeds, you can apply a double layer of cold patch to increase repair strength and stick two layers of the same size cold patch at a symmetrical position inside the tire to maintain wheel balance. 3. Inflate: After reinstalling the tire, if inflating manually, start vigorously to quickly inflate and seal both sides of the tire, then install the valve stem and inflate to the specified pressure before tightening the valve stem. Finally, check for leaks; if there are none, the tire can be reinstalled and used.
