How to Seal Tubeless Mountain Bike Tires: A Step-by-Step Guide
To seal tubeless mountain bike tires, first remove the tire and clean the rim and tire bead thoroughly. Apply a tubeless valve to the rim and insert it. Add sealant to the tire, then inflate the tire with a high volume/low pressure pump. Shake the tire to distribute the sealant evenly inside. Then, re-install the tire over the rim, ensuring that the tire bead is seated properly. Inflate the tire to the recommended pressure and check for sealant leaks. Finally, ride the bike to distribute any remaining sealant to any small gaps in the tire.
