Using your Schwalbe Av7d Schrader tube is easy. First, make sure your wheel is clean and free of any sharp objects. Then, deflate the old tube and remove it from the tire. Place the new tube inside the tire, making sure the valve stem is centered in the valve hole of the rim. Slowly inflate the tube using a Schrader - compatible pump until it reaches the recommended pressure. When it comes to maintenance, check the tube regularly for any signs of wear or damage. Keep it away from sharp tools and rough surfaces. If you're not using the tube for a long time, store it in a cool, dry place. Remember, over - inflating can cause the tube to burst, so always follow the pressure guidelines.
