- Does using Great Stuff foam to make a flat free tire work? Let's see if it works. So many youtube videos claim it does, but even cured great stuff can easily be squished between my fingers. I'm skeptical...
Part 2: • DIY flat free tire. Do...
I only use my log splitter a few times a year, so it sits a lot. The tires keep going flat, and now the tire is ruined. Rather than buying a new tire and continuing to wrestle with this thing every time I go to use it, I decided to try the 'DIY flat free tire' method that is elsewhere on youtube. Basically, you stuff foam chunks into the tire until you can't get any more in, then you fill the rest with great stuff expanding foam.
I used blue-board foam, which is much denser and would definitely support more load, as in construction this foam is used under concrete slabs without collapsing. Some of the DIY vids I saw people were using packing peanuts and regular styrofoam, which seems even less likely to work in my opinion.
My end results were ... instructive.

You said it all, i bought a pair of harbor fright tiers for a pull behind cart i made for my lawn tractor,
Parked it outside one season, went back to use it within a year, the tire was eaten down to nothing, like rodents ate it.
I bought 2 15" replacements from
Menard they have lasted 5 years.
This cart can hold 70 cubic feet of stuff, moved a Brand New 2017 table saw to the basement with it that has cast iron top and wings my son won and gave me. Its about 1500 lbs i belive total. It has a 120 volt motor on it my grizzly has a
3 hp 240 volt motor 2 phase.
I bought in 2001 thats never been used.
Inject a little bit of water into the tire because it needs moister to cure. I just did my snow blower tires and before injecting the foam I squoshed some water in there . I'll see in a couple days if it works.
I filled an old tractor tire with concrete about 40 years ago. The rim was rusted out and the tire was old. We removed the inner tube and put old steel cable in for reinforcing. We cut a big slot in the side to pour concrete in and used a come-a-long to create a relatively flat tread. Also added a few lag bolts thru the sidewalls. It weighed probably 500 lbs and I used a loader to remount it after a week of curing. It worked great but didn’t have as much traction as the other wheel. Also couldn’t drive over 5-6 mph or it would scare hell out of you. This whole idea was inspired and created by lots of beer.
gosh, thanks for good laugh... still laughing...
...I have tractors, another reason why this was very funny.
Get new tires. When you store the splitter put it up on a block to keep the tires off the ground. Then, cover the wheels with something or smear the tires with some kind of grease, or both, so the sun won't rot the rubber. I think maybe the tire was just too large, but I'm not an expert. Thanks anyway, for the upload.
If you put woodscrews in the vent holes it would prevent the leakage...also injecting water prior to the foaming
I did it with a much smaller tire and a two piece rim, using silicone in the caulking tubes,( used three to fill it) but the bead was too wide and I had to wedge open the sidewalls to get the fourth tube in there. Then when I tightened the bolt ,the beads were secure. Expensive, but I'll never have to repair it again. It was on a PTO finishing mower.
I have a video on my page about this also. GSF requires moisture to setup. You have to put a little water in the tire or it wont setup. One thing I leaned after my video is to use the can up side down. There is no straw inside. I think that load may be too much for foam. How much does that thing weight? Do you pull it down the road? Nice job though. I like the fast forward sections.
Love the creativeness..from the s.west 🏜phx.az.Thx.🚜
I tried pouring concrete into a old wheelbarrow tire once. It works. Use a hole saw and cut a 2 inch hole. Shove it full of concrete and it rolls. Heavy but it does work.
could you use a ratchet strap to push the bead out a bit?
Thanks for trying!
Did this to a larger tire. The foam worked great. The problem was it was an old tire.The holes were too small. As the foam expanded the holes sealed . The tire exploded. Glad I wasn't near.
lol use butain next time
The Air Force has a lot of aircraft on static display the tires are filled with two part ridge foam. They pull a vacuum on the inner tube. Then break the vacuum with the two part foam they fill the tire so the density is near running pressure.
This "fix" is a total waste of time & money. I did add the "Great Stuff" to a front tire on my ZTR mower,, let it set overnight to cure & it went flat. I redid it after adding a couple tablespoons water as GS instructions suggested. I screwed the tire bead to the wheel but that didn't help. It went flat for the second time. I finally mounted a new tire after cutting off the old tire, cleaning up the mess in the wheel, paainting the wheel. Never never put that crap in a tire.
did the same thing to me on my ZTR !!! FOAM DOES NOT WORK !!! The guys at the Tire Shop are pissed at me now because it was a mess to get the tire off the rim.
I put air into it to reseat the tire to rim, then drill wholes and add foam. Also, not rated for heavy applications...
I made a couple of mistakes. I didn't clean out the old Slime. I used pieces of the flexible soft styrophome instead of the stuff you used. At any rate I am starting over .
you forgot to put water in the tire, just a little bit
Thanks for the info:-)
I know this is a old vid but put a ratchet strap around the tire and it will push the bead out just take it off before the foam sets too much
How about putting the inner tube inside the tire and spraying the foam into the inner tube?
6:12 I know this tools been replaced with a better system now.
But for other items, you can buy a whole trailer spindle and trailer wheel assembly from Northern tools
. Why didnt you use the valve stem to shoot spray foam into the tire. What was the broken chunks for? Try shooting water into the tire first. It aids in the curing of the foam. Also use the foam that is heavy and will bow door jams and window sills out.
I bought 2 15" tires from harbor freight for a homemade tractor cart i made out of bed frames that able to hold 70 cubic foot of materials
After being parked outside for 1 winter i went to use it both tires were gone eatten away. The rubber was trash. I had to replace them.
Went to menards they had them with snap in berrings to fit 5/8- 3/4-and 1" shafts they came with metal berrings 2 sets.
Home depot had some for my lawn tractor that used plastic bushings
I put the orignal cub cadet wheels back on after swapping out the rubber on both of them.
I wont buy another harbor freight wheel that size.
First, a disclaimer for my comment. I haven't tried this - and I watched these 2 videos in reverse order. I also have not read all the comments, just going to add mine. Could you have added the STUFF into the tube, and left it expand. Then you may have added air as needed. Just wondering.
Always hold the can up side down, put water in the tire, skip the foam bits and make sure the bead is set, it will work...
How do you set the bead on a popped tire? Yes you can use a ratchet strap around the circumference, but that didn't work on these tires. I think there may be a place for this foam fix on tires that carry very little weight, but for something like my log splitter that requires significant PSI to support it, there's no way this foam is going to work. Nice wide lawn mower tires, maybe.
Make a wooden Roman Chariot wheel out of metal...or say, that other stuff...wood. Seriously. Appropriate size tube for a hub, metal disk from 1/4" plate and a tire from 4" steel tubing. Use a lot of fire to bend the tubing. Or say 3 one inch metal tubes side by side. That's small enough to bend with a tubing bender. Then you could cut the tread section from the old tires and attach them for "shoes". Low speed farm use. Just don't take it on the highway.
You can't expect ANY thing from Harborcrap!
i just put a tube in mine. about the same cost at the tire shop. it'll last as long as the mower does.
I feel in my soul like you should have used air to pop it back on the bead before you drilled the holes.
That's a good idea. Don't think it would have helped in the end though. I've read elsewhere that a flat free tire with this great stuff foam can handle about 3 psi only.
My problem with this is...what happens when the tread is gone and you need new tires.
But no before the foam was added you should have tried setting the bead...and then bleed pressure and drill holes. That way when you spray the foam it's inside the sealed off tire and you are putting the weight on the sidewalls and not just the foam. It may be the reason your foam blew out so easily.
There are manufactured tires just like this they are sold with the bead locked in and filled with foam. I think the bead lock has something to do with it working. You need a sealed pressure chamber to start with.
If the tire filled with foam squishes letting the air out of the foam and there is nowhere for the air to go...it doesn't go flat. Gotta set the bead before you fill it with foam.
If that fails after that than sir, you are an honorable scientist spreading truth throughout the dark forest.
All I'm saying is that it's a plausible arguable variable in your experiment.
No disrespect intended.
Cured it still squished between your fingers? That does not sound like great stuff to me, that stuff cures rock hard unless you specifically get the stuff that's meant to stay soft like around door and window trim.
Put a ratchet strap around thetire to set the bead make it tight untill it pops onto the rim
The foam needs water to fully expand check your can instructions
thank you. now I know what not to buy.
You should remove the air valve then spray water in it spinet then put the foam and then put a cap on the stem that would’ve worked never take the tire off
Came off the bead, it was never _on_ the bead.
personally, your patch looked good, shouldve just slapped the tube back in
The "Great Stuff" foam absolutely does not work. I added about 3 tablespoons water before adding the foam. I took great care in injecting the foam in one of my front tires on my mower & let it cure 24 hours. It lasted about one hour. It was a waste of time & money. I now have a new tire & tube on it.
A can a day would’ve been expensive
Thats why it fell apart you didn't fill it with the right foam. you used the foam board also. Try using the 3m foam or loctite foam works very good for light duty.
There are definitely better types of foam out there that would work, but the point was to test great stuff foam, which people often claim works well. I was skeptical, and I was right. It doesn't work.
Ok expanding cement.
👍🇺🇸
How about filling the tires with concrete? :) For things that move slowly, must carry a lot of weight and are moved by a motor (like snow blowers, lawn mowers, walk behind tractors etc.) it should be fine...
Doesnt work, the foam gets hard, then crushes then you lose what air the foam held in it. One big FAIL.
It needs water to cure
Dont work on anything I have. My Craftsman lawn tractor is too heavy. Flat spots every time I leave it parked over night. Some leave the mower on blocks between uses. With the big gap you dont get flat spots. The tire will be flat all the way around. My bs alarm is sounding off reading these posts.
it failed because you put the other foam in it before the spray foam.
You used the tire too early, foam turns dark yellow when its properly cured.
If two weeks isn't long enough, then I'd rather do something else. How long is long enough??
FarmCraft101 Month atleast, maybe two, so its definetly not a quick fix. Not sure did you use same foam as I seen used, since it needed water to expand.
Just bought a new wheels are not that expensive
So you failed not the other way around
for the weight it looks like you have use 2 part 8lb poly urethane foam. the foam in the great stuff is 2lb or less. this is a pourable foam but if you have an air compressor you can mix and with a 1 gallon air tight bucket and some throw away tub can pump it in. if you would like more info respond and I will give more details if you want.

+Roger Paradis Agree, there are ways to do it with more expensive foams, but the point was to test the great stuff method which is often shown on UA-cam. Rather than mess with $30 foam, I'd just buy a flat free tire and be done with it.
Jesus Christ !!! Why is this recommended to me !!! Smh talk about a mess
You did it completely wrong.
