How to Pump Up Your Mountain Bike Tire Properly
To pump up a mountain bike tire, first, unscrew the valve cap. Then, attach the pump nozzle to the valve and secure it. Begin pumping air into the tire, checking the pressure periodically with a pressure gauge until you reach the recommended pressure for your tire. Once you reach the desired pressure, remove the pump nozzle from the valve, screw the valve cap back on, and you’re ready to ride.
