How to Easily Put Air in a Tubeless Mountain Bike Tire
To put air in a tubeless mountain bike tire, first remove the valve cap and secure the pump head to the valve. Use a floor pump with a pressure gauge, and start pumping. Continue until the desired pressure is reached, typically around 25-30 psi for mountain bike tires. Once finished, remove the pump head, replace the valve cap, and ensure there are no leaks.
