How to Pump Up Your Mountain Bike Tires Like a Pro
To pump up your mountain bike tires, first, make sure you have a suitable bike tire pump with a gauge and an air compressor or manual pump. Next, unscrew the valve cap and press the pump head onto the valve tightly. Then, inflate the tire to the recommended pressure level indicated on the tire sidewall or in the owner’s manual. After reaching the desired pressure, remove the pump head and screw the valve cap back onto the valve securely.
