Changing a lawn mower tire is a relatively simple process that can be completed in a few minutes with the proper tools. In order to change a lawn mower tire, you need a jack, a pair of pliers, a screwdriver, a tire iron, a ratchet strap, an air hose and the new tire.
- Prepare the lawn mower
Put the mower in gear, and, if there is one, put on the parking brake. This prevents the mower from moving and helps you to keep the tire sturdy as you remove it. Place the jack underneath the mower, and crank it upwards so that the tire you are replacing is lifted off of the ground. It is best to perform this on level ground.
- Remove the old tire
Use your pair of pliers to remove the black rubber boots on the tire you are replacing. Move slowly, and try not to tear the boots while doing this. With your screwdriver, pry the metal clip off the tire. You may need to apply quite a bit of pressure to pop this clip off the tire. Once the clip is removed, unscrew the valve core so that the air is released. Pry the tire iron against the tire without striking the inner rim to break the tire beads. Once the beads are broken, remove the tire.
- Insert the new tire
Place your new tire onto the rim, and try to place the rim inside the tire. You need to use the tire iron to work the beads around the rim. Secure the beads with your ratchet strap. Use your air hose to inflate the tire until it is even with the rest of the tires.
