How do you change a bicycle tire?


assistant
Start by taking off the wheel. For this, open the quick release for the brakes or detach the brake cable. Then, unscrew the axle to take off the wheel. Following, you have to deflate the tire and be able to pull out the tube from underneath the tire. Pry the tire off the rim with tire levers. Once the tire comes off, you can replace the tube and work it back underneath the tire. Remember only to inflate the tube completely once both tube and tire are fitted on the rim. To mount the wheel again, follow the above-described steps in reverse order.
