How to easily pump air into your mountain bike tires
To pump air into mountain bike tires, start by checking the recommended tire pressure on the sidewall of your tire. Then, attach the pump head to the valve of the tire and firmly hold the pump in place. Begin pumping air into the tire while keeping an eye on the pressure gauge. Stop pumping once you reach the recommended pressure and remove the pump head from the valve. Finally, check the tire pressure one more time using a separate pressure gauge before riding.
