Country Lore: Avoid Flat Lawn Mower Tires

Lawn mower tires won't hold air? Fill them with foam and they'll stay firm forever.

| April/May 2009

I grew tired of having to air up the tires on my riding mower each time I used it. I tried “Slime” tire sealant, but with all the holes they had in them, the tires still went flat.

Then I had a hairbrained idea: inject all four lawn mower tires with foam. It worked great.

Here’s how to do it:

  1. Purchase at least two cans of minimal expanding rigid foam.
  2. Jack up the mower.
  3. Drill a hole just large enough for the canned foam’s spray tube. I turned the tire/wheel assembly so the valve stem was at the top, and then drilled the hole in the center tread of the tire itself. I removed the valve stem insert as well.
  4. Insert the tube into the tire and spray the foam into the tire. Watch for foam to start exiting the valve stem area; the foam will just have about filled the tire by that time. This also allows any air in the tire to exit. Replace the valve stem insert and cap to keep the foam from exiting.
  5. Keep filling the tire. Do this until the foam starts to exit the hole you drilled.
  6. Allow the foam-filled tire to remain jacked up for a few days to make sure the foam has cured.

After a couple of uses, the tire softened up some and started to get a flat spot when it sat for a few days. To remedy that, I added more foam.



Even if I have to do this a few times, eventually I think the foam will be compressed to a certain point where it will not compress anymore.

If you don’t want to do all this, there are tire shops that will fill tires for you.

I used the plans at WWW.EASYWOODWORK.ORG to build my own – I highly recommend you visit that website and check their plans out too. They are detailed and super easy to read and understand unlike several others I found online. The amount of plans there is mind-boggling… there’s like 16,000 plans or something like that for tons of different projects. Definitely enough to keep me busy with projects for many more years to come haha. Go to WWW.EASYWOODWORK.ORG if you want some additional plans :)

Try stans no tubes... which is just a product you put in your tire. Not anywhere close to the green slime stuff that doesn't work. Check out the attached video. https://m.youtube.com/watch?v=FTlZvOVG8zs
