How to Change Rear Tire on Mountain Bike: A Step-by-Step Guide
To change the rear tire on a mountain bike, first shift the chain onto the smallest gear. Release the brake, flip the bike upside down, and use a wrench to remove the bolts that hold the wheel onto the bike. Take off the quick-release skewer, slide out the rear wheel, and remove the tire from the rim. Install the new tire, then slide the axle back in and re-attach the bolts and quick-release skewer. Finally, inflate the tire to the recommended pressure and adjust the brakes if necessary.
