Frustrating, right? But don’t despair! This article will guide you step by step through the process of replacing a flat lawn mower tire with a brand new tube, ensuring you’re back to mowing in no time.
This article will cover everything from choosing the right tube to properly installing it, along with tips for avoiding future flats. By the end, you’ll have the knowledge and confidence to tackle this common lawn mower maintenance task like a pro.
A Quick Overview
Replacing a flat lawn mower tire with a tube is a relatively straightforward process that involves removing the tire, installing a new tube, and then re-mounting the tire.
What You’ll Need
Before you start, gather these essential tools and supplies:
- New tire tube: Choose a tube that is specifically designed for your lawn mower’s tire size. You can find this information on the sidewall of your existing tire.
- Tire irons: These specialized tools are designed to help you pry the tire off the rim.
- Air compressor: You’ll need this to inflate the new tube once it’s installed.
- Soap and water: This helps you detect leaks in the tube before you inflate it.
- Work gloves: Protect your hands while working with the tire.
- Optional: Tire lubricant: This can make it easier to mount the tire back onto the rim.
Preparing for the Replacement
Now that you have all the necessary tools and materials, it’s time to prepare the tire for the tube replacement:
1. Removing the Flat Tire
Step 1: Locate the valve stem on the flat tire. This is the small metal piece that sticks out from the tire and allows air to be pumped in.
Step 2: Use a tire iron to gently pry the tire off the rim, starting at the valve stem. Work your way around the tire, using the tire irons to loosen the tire bead from the rim.
Step 3: Once the tire is completely removed, inspect the tire for any obvious punctures or damage. If you find any damage, you may need to replace the entire tire.
2. Inspecting the Rim
Step 1: Carefully check the rim for any sharp edges or rust that could cause the new tube to puncture.
Step 2: Use a wire brush or sandpaper to remove any debris or rough spots from the rim.
Step 3: Clean the rim thoroughly with soap and water to remove any dirt or grime.
3. Installing the New Tube
Step 1: Open the valve stem on the new tube and insert it through the hole in the rim. Make sure the valve stem is positioned correctly so that it aligns with the valve stem hole in the tire.
Step 2: Carefully position the tube inside the tire. Avoid twisting the tube or pulling it excessively.
Step 3: Inflate the tube slightly, just enough to give it some shape. This will make it easier to mount the tire back onto the rim.
Step 4: Start at the valve stem area and use the tire irons to carefully work the tire bead back onto the rim. Be sure to spread the tire irons evenly around the rim to avoid damaging the tube.
Step 5: Once the tire is fully mounted, use a small amount of soap and water to check for leaks. This will help you find any small holes that you may have missed during installation.
Step 6: If you find any leaks, use a tire patch kit to seal the hole. These kits are available at most auto parts stores.
4. Inflating the Tire
Step 1: Once you’re confident the tire is properly mounted and there are no leaks, use an air compressor to inflate the tire to the recommended pressure. You can find the recommended pressure on the sidewall of your tire.
Step 2: After inflating the tire, double-check for any leaks and ensure the tire is properly mounted on the rim.
Step 3: Replace the tire on your mower and you’re ready to mow!
Tips for Preventing Flat Tires
While punctures can happen, here are some helpful tips to reduce the risk of flat tires on your lawnmower:
1. Regular Inspection: Take the time to regularly inspect your mower tires for signs of wear, damage, or low air pressure. Catching issues early can prevent them from turning into bigger problems.
2. Proper Maintenance: Keep your lawnmower tires properly inflated to the recommended pressure. This helps maintain the correct tire shape and reduces the risk of punctures.
3. Careful Operation: Avoid running your mower over sharp objects or rough terrain.
4. Consider Upgrading to Tubeless Tires: For added protection, consider upgrading your lawnmower to tubeless tires. These tires are more resistant to punctures and don’t require a separate tube.

Frequently Asked Questions
Q1: Why would I need to put a tube in my lawn mower tire?
A: Lawn mower tires are often designed to be tubeless, relying on the tire’s construction and a sealant to prevent air leaks. However, if the tire develops a puncture or other damage that the sealant can’t repair, you’ll need to install a tube to keep it inflated. Additionally, some older lawn mowers might have tires that were originally designed with tubes but have lost them over time.
Replacing a damaged tire with a new one might seem like the easier option, but installing a tube is often a more economical solution, especially for smaller punctures.
Q2: What tools do I need to install a tube in a lawn mower tire?
A: You’ll need a few basic tools to successfully install a tube in your lawn mower tire. These include a tire iron or wrench to remove the tire from the wheel, a jack to lift the mower, a pair of pliers to help remove the valve stem from the tire, and a small amount of soapy water to help with the installation. It’s also a good idea to have a pump or compressor on hand to inflate the tube once it’s installed.
Having a tire lever or two can also be helpful, although they’re not strictly necessary if you’re careful and have strong hands.
Q3: What size tube do I need for my lawn mower tire?
A: To find the correct size tube for your lawn mower tire, you need to check the tire’s sidewall. The information you need will be listed there, including the tire size and the tube size. It’s crucial to use the correct size tube; an oversized tube won’t fit properly, and an undersized tube could be susceptible to damage.
If you’re unsure about the correct size, consult with a local tire shop or refer to your mower’s owner’s manual.
Q4: How do I remove the old tire from the wheel?
A: To remove the tire from the wheel, use your tire iron or wrench to loosen the lug nuts on the wheel. Once they’re loose, you can use the jack to lift the mower off the ground, allowing you to remove the wheel entirely.
With the wheel removed, you can pry the tire off the wheel rim using your tire iron or tire levers. Be careful not to damage the wheel rim during this process.
Q5: How do I install the new tube?
A: Before installing the tube, inspect it for any damage or imperfections. Once you’re satisfied, carefully position the tube inside the tire. Ensure the valve stem is positioned through the hole in the tire’s sidewall where the valve stem will be installed. You can use a little soapy water to help guide the tube into the tire.
Be sure to avoid pinching or twisting the tube during this process.
Q6: What if the tire is too difficult to remove?
A: Sometimes, the tire can become stubborn and difficult to remove from the wheel. If this happens, you can try using a lubricant like soap or WD-40 to help loosen the tire. If you still have trouble, it’s best to take the wheel to a tire shop for professional assistance.
Forcing the tire off the wheel could cause damage to either the tire or the wheel, so it’s always best to err on the side of caution.
Q7: How do I inflate the new tube?
A: Once the tube is installed, you can start inflating it using your pump or compressor. You’ll need to inflate the tube to the pressure specified on the tire’s sidewall. Be careful not to overinflate the tube as this could lead to damage or premature failure.
Once the tube is inflated, check for any leaks or imperfections. If you find any, you may need to replace the tube or further inspect the tire for any damage that might be causing the leak.
