Once you get most of the way around, you will need to use the tire levers again to assist you with the unyielding tire. Be sure not to pinch the new tube between the tire and the rim during this step because you can tear the tube. Once the tire pops back onto the rim, take your pump and fill the tire completely. After you get the wheel back on your bike, you’ll be ready to ride! What could cause a tear in the new tube? A) twisting it around the rim B) pinching it between the rim C) poking it with a tire lever D) failing to inflate it properly
