Let’s get started!
Identifying the Problem: Flat Tire or Puncture?
Before you dive into changing the inner tube, take a moment to determine if the problem is truly a flat tire. Sometimes, the issue might be a loose valve stem, a slow leak, or even just a lack of air.
- Check the Valve Stem: Make sure the valve stem is securely fastened and not damaged.
- Inspect for Punctures: Look for obvious punctures or signs of damage on the tire.
- Test for Slow Leaks: If you can’t find a puncture, spray some soapy water around the valve stem and tire. If bubbles form, there’s a leak.
If you suspect a flat tire or a puncture, it’s time to move on to the next step – gathering your tools.

FAQ
What tools do I need to change a lawn mower tire inner tube?
You’ll need a few basic tools to change a lawn mower tire inner tube. First, you’ll need a tire iron or wrench to loosen and tighten the lug nuts. Next, you’ll need a jack to lift the mower off the ground so you can access the tire. You’ll also need a pair of pliers to remove the old valve stem from the tire. Finally, you’ll need a new inner tube that’s the correct size for your lawn mower.
How do I remove the old tire from the rim?
To remove the old tire from the rim, you’ll need to break the bead. The bead is the edge of the tire that sits on the rim. To break the bead, use a tire iron or wrench to pry the tire off the rim. You may need to use a little force, but be careful not to damage the rim. Once the bead is broken on one side, you can remove the tire from the rim.
How do I install the new inner tube?
Installing the new inner tube is the reverse of removing the old one. First, make sure the inner tube is inflated slightly so it’s easier to handle. Then, carefully insert the inner tube into the tire, making sure the valve stem is pointing out through the valve hole in the rim. Once the inner tube is in place, you can start to inflate it. Make sure you don’t over inflate the tire, as this can damage the inner tube.
How do I re-install the tire on the rim?
Once the inner tube is inflated, you can re-install the tire on the rim. Use the tire iron or wrench to pry the tire back onto the rim. You’ll need to work around the entire rim, making sure the tire is seated properly. Once the tire is back on the rim, you can tighten the lug nuts.
How do I check for any leaks in the new inner tube?
After installing the new inner tube, it’s important to check for any leaks. You can do this by spraying soapy water around the valve stem and tire bead. If you see bubbles forming, that indicates a leak. You can then repair the leak using a patch kit.
How do I know what size inner tube I need?
The size of the inner tube you need will depend on the size of your lawn mower tires. You can find the size of your tires on the sidewall of the tire. The size will be listed as a series of numbers and letters, such as 13×5.00-6. This means the tire is 13 inches in diameter, 5 inches wide, and has a 6-inch rim diameter.
What should I do if I can’t find the correct size inner tube?
If you can’t find the correct size inner tube, you may be able to use a slightly different size. For example, if you can’t find a 13×5.00-6 inner tube, you may be able to use a 13×5.50-6 inner tube. However, it’s important to make sure the new inner tube is the correct size for your rim. If the inner tube is too small, it could slip off the rim. If the inner tube is too large, it could be too tight and make it difficult to install.
