How to Change a Tire on a Riding Lawn Tractor

Change flat lawn mower tires as soon as possible.

You must change the tire on a riding lawn tractor when the tire becomes worn or is flat and no longer inflates. The process is similar to changing the tire on your car. The tires on the tractor are smaller, however, and easier to work with. You can change a tire on a riding tractor by first purchasing a replacement tire from a tractor supply store or dealer.

Things You'll Need

• Socket wrench
• Car jack
• Flatblade screwdriver
• Air compressor

Instructions

1. Place the tractor on a flat surface, such as a driveway or in a garage.

2. Loosen the lug nuts or bolts on the wheel by turning the socket wrench to the left.

3. Place a car jack under the chassis or frame of the tractor near the tire you're replacing, and jack it up off the ground.

4. Remove the lug nuts or bolts from the wheel, and take the wheel off the axle.

5. Place the wheel on the ground, face up, and locate the valve stem. Press down on the valve stem to let the air out of the tire.

6. Separate the edge of the tire from the rim by using a flatblade screwdriver. Wedge the screwdriver in between the tire and the rim. Work your way around the tire until the tire has separated from the rim. Insert the flathead screwdriver in between the tire and the rim, and pry up to force the tire up over the rim. Repeat this step around the perimeter of the tire. Pull the tire forward, and repeat to remove the other side of the tire from the rim.

7. Place the new tire over the rim and press down to force the back of the tire down over the rim. Use the flatblade screwdriver to force the tire over the rim if necessary. Push the tire forward, and repeat for the front of the tire.

8. Inflate the tire using an air compressor. When tire begins to inflate, you will hear a popping sound when the tire expands out to the rim.

9. Place the wheel back on the axle, and tighten the nuts or bolts with the socket wrench. Lower the tractor.

Tips & Warnings

• Refer to the owner's manual of the tractor for the correct air pressure for the tires.

• If you pry too hard with the screwdriver, you may bend the rim, which will require repairs or even a new rim.
