How to Easily Fill Air in Your Mountain Bike Tire
To fill up the air in the mountain bike tire, first, check the recommended tire pressure range on the sidewall of the tire. Then, attach the bike pump nozzle to the tire valve stem and pump air until the desired pressure is reached. Use a tire pressure gauge to accurately check the pressure levels. Release air if necessary using the nozzle lever or pressing the valve core briefly. Replace the valve cap to ensure proper seal and avoid dust, debris or moisture entry.
