How to Easily Remove the Rear Tire on Your Mountain Bike in Quick Steps
To remove a rear tire on a mountain bike, first, shift the gears so the chain is on the smallest cog. Then, release the rear brake and loosen the quick-release skewer or axle nuts. Slide the wheel out of the frame and remove the chain from the cassette. If the tire is difficult to remove, use a tire lever to pry it off the rim. Once the tire is removed, replace the used tube with a new one if needed. To reinstall the tire, reverse the process and ensure that the wheel is centered and the brake is adjusted correctly before tightening the skewer or axle nuts.
