How to Add Sealant to Tubeless Mountain Bike Tires: A Step-by-Step Guide
To add sealant to tubeless mountain bike tires, first remove the valve core with a valve core remover tool. Then, pour the recommended amount of sealant into the tire through the valve stem. Put the valve core back in and re-inflate the tire to the recommended pressure. Shake the tire to distribute the sealant and ride the bike to further distribute it. Check the sealant every few months and add more as necessary.
