How to Insert a Tube in a Lawn Tractor Tire

When you mow with your lawn tractor, you can encounter some rough terrain or materials that may puncture or blow out your tires. Most lawn tractor tires have a tube on the inside that keeps the tire full when the tube is inflated. When a tube-inflated tire goes flat, you will have to insert a new tube into the tire and seal the tire to the rim for proper inflation.

Things You'll Need

• Jack
• Wrench set
• Flathead screwdriver
• Tire tube
• Ratchet set
• Air compressor

Instructions

1. Jack up the axle on your lawn tractor 2 to 3 inches. Unscrew the the bolts holding the wheel onto the axle with a wrench and pull off the wheel with the flat tire. Pull the punctured tube out of the tire and replace it with the new tube.

2. Lay the flat tire on the ground. Kneel on the tire sidewalls and insert the Flathead screwdriver between the rim and the tire to pry off the tire.

3. Lay the rim flat on the ground. Push the tire onto the rim by kneeling on top of it. Poke the new tube's air valve stem through the rim's stem valve hole, and use the screwdriver to pry the valve stem through the rim hole.

4. Wrap the ratchet strap around the circumference of the tire. Ratchet the strap down tightly until the sidewalls of the tire bow out and touch the rim.

5. Inflate the tire until the tire seals against the rim, then remove the ratchet strap. Finish blowing up the tire to the air pressure specified on the new tube.

6. Bolt the wheel tightly back onto the lawn tractor axle. Lower and remove the jack.
