How to Properly Use Tire Levers on Your Mountain Bike
Tire levers are used to remove or install a tire on a mountain bike. To use them, first, release the brakes and choose which side of the tire you want to work on. Insert one of the levers between the tire bead and the rim and pry it off the rim. Then, slide the lever around the edge of the tire until you can easily remove it from the rim. Repeat the process on the other side and you can now replace or repair the tire as necessary. Remember to be careful as tire levers can scratch the rim.
