How to Change a Back Tire on a Mountain Bike: The Ultimate Guide for Expert and Novice Riders
To change a back tire on a mountain bike, first shift the chain to the smallest gear on the back and then loosen the quick-release lever or bolts that hold the wheel in place. Lift the rear wheel off the ground and pull the wheel towards you to remove it from the bike frame. Next, use tire levers to remove the damaged tire from the wheel and replace it with a new one. Finally, fully inflate the tire and reattach the wheel to the bike frame, making sure it is securely in place.
