Getting Ready: Tools and Materials
Before you start, make sure you have the following tools and materials:
- A new inner tube: Make sure the size matches your existing tire. You can find inner tubes at most hardware stores and online retailers.
- Tire iron: This is essential for removing and replacing the tire from the rim.
- Air compressor or bicycle pump: You’ll need this to inflate the new inner tube.
- Soap and water: This will help you lubricate the tire bead, making it easier to mount and dismount the tire.
- Optional: A tire pressure gauge: This will help you ensure the tire is inflated to the correct pressure.
Step-by-Step Guide to Replacing a Lawn Mower Tire Inner Tube
Follow these steps to replace the inner tube in your lawn mower tire:
1. Remove the Flat Tire
- Locate the flat tire: The most common sign of a flat tire is a deflated or visibly punctured tire.
- Park the lawn mower on a flat surface: This will prevent it from rolling while you’re working.
- Set the brake: Engage the parking brake to ensure the lawn mower remains stationary.
- Remove the tire: Using the tire iron, carefully pry the tire off the rim. It may be necessary to work the tire iron around the entire tire, loosening it in sections.
2. Inspect the Tire and Rim
Once the tire is off the rim, take the opportunity to inspect both the tire and the rim for any damage.
Inspecting the Tire
- Check for punctures: Look for any visible holes or tears in the tire. If you find any, you may need to replace the tire entirely.
- Examine the tire tread: Check for excessive wear and tear. If the tread is worn down significantly, it may be time to replace the tire.
Inspecting the Rim
- Look for rust or damage: Check for any rust or damage to the rim. If the rim is damaged, it may need to be replaced.
- Check for bent spokes: If the rim has bent spokes, it may be difficult to mount the tire correctly.
3. Prepare the New Inner Tube
- Inflate the inner tube slightly: This will help you ensure the inner tube is correctly sized and that there are no leaks. Inflate the inner tube to a very low pressure, just enough to give it some form.
- Inspect the inner tube: Check for any defects or punctures.
- Lubricate the inner tube: Using a small amount of soap and water, lubricate the inner tube. This will make it easier to slide the tire onto the rim.
4. Mount the Inner Tube
- Align the valve stem: Ensure the valve stem on the inner tube is positioned correctly on the rim, aligned with the valve stem hole.
- Start with the tire bead: Begin by placing one side of the tire bead onto the rim. You may need to use your hands to help guide the tire bead over the rim.
- Work your way around: Once you’ve gotten one side of the tire bead over the rim, carefully work your way around the rest of the tire. You may need to use the tire iron to help you with this step. Use caution and avoid excessive force.
- Check the tire bead: Make sure the tire bead is fully seated on the rim. If you see any gaps or bulges, carefully adjust the tire bead until it sits properly.
5. Inflate the Tire
- Inflate the tire slowly: Use the air compressor or bicycle pump to inflate the tire. Inflate slowly to avoid any sudden pressure changes that could damage the inner tube.
- Monitor the tire pressure: Use a tire pressure gauge to monitor the tire pressure. You should inflate the tire to the pressure specified in your lawn mower’s owner’s manual.
- Check for leaks: Once the tire is inflated, check for any leaks. Listen carefully for any hissing sounds. If you hear a leak, carefully deflate the tire and repeat steps 3 through 5, carefully inspecting for any punctures in the inner tube.
6. Remount the Tire
- Reinstall the tire: Once you are sure the tire is properly inflated and there are no leaks, you can remount the tire on the lawn mower. Make sure to position the tire properly on the axle.
- Tighten the nuts: Use a wrench to tighten the nuts that hold the tire on the axle.
7. Test Drive and Adjust Pressure
- Start the lawn mower: Turn on your lawn mower and let it run for a few minutes to allow the tire to warm up.
- Test drive: Take your lawn mower for a short test drive to ensure the tire is holding air and there are no issues.
- Adjust tire pressure: If necessary, adjust the tire pressure to the recommended level.
Tips for Success
- Patience is key: Replacing an inner tube takes some patience and effort. Don’t rush the process, as this can lead to mistakes.
- Use the right tools: Using the correct tools will make the job easier and help you avoid damaging the tire or inner tube.
- Protect your hands: Wear gloves to protect your hands from cuts and abrasions while working with the tire and tools.
- Watch a tutorial: If you’re unsure about any of the steps, there are many helpful videos available online that can demonstrate the process in detail.

Now you’re equipped to handle minor repairs like this yourself. Remember, routine maintenance, including checking tire pressure, can prevent flat tires and keep your lawn mower running smoothly for years to come. So grab your tools and get back to mowing!
FAQs
This guide is for lawn mower tires that originally came with inner tubes. You can tell if your tires need an inner tube by looking at the sidewall. If it says “tube type” or “TT,” then your tires need inner tubes. If it says “tubeless” or “TL,” then your tires do not need inner tubes.
How do I know what size inner tube to get?
The size of the inner tube you need is printed on the sidewall of your tire. It will typically be a number like 4.00-8, which means the tire is 4 inches wide and 8 inches in diameter. Make sure to get an inner tube that matches the size of your tire exactly.
What tools do I need to change a lawn mower tire?
To change a lawn mower tire, you will need a few basic tools: a tire iron, a jack (or something to lift the mower), a lubricant like soapy water or tire lube, and a new inner tube. It’s helpful if you have a pair of gloves and a towel to clean up any spills.
How do I remove the old tire from the rim?
Before removing the old tire, loosen the lug nuts on the wheel. Then, use a jack to lift the mower so that the tire is off the ground. Next, use a tire iron to pry the tire bead off the rim. Work your way around the tire, prying it off the rim in sections. Be careful not to damage the rim.
How do I install the new inner tube?
Once the old tire is off, you can install the new inner tube. First, make sure the inner tube is inflated slightly. Then, position the inner tube inside the tire. Carefully work the tire bead back onto the rim, starting at one point and working your way around. Once the tire is fully seated on the rim, inflate the inner tube to the recommended pressure, which is usually listed on the tire sidewall.
What should I do if the tire won’t seat on the rim?
If the tire won’t seat on the rim, you may need to use a tire iron to help it along. Make sure to work slowly and carefully, and be careful not to damage the rim or tire. You can also try using a lubricant like soapy water or tire lube to help the tire slide onto the rim more easily.
How do I know if I’ve properly installed the inner tube?
Once the new inner tube is inflated, it should be snug and even on the rim. There should be no wrinkles or bulges in the inner tube. If you see any of these, it means the inner tube isn’t properly seated and you will need to remove the tire and reposition the inner tube.
