You know you have always wondered if this would work. Let's find out! Check us out on INSTAGRAM and see what we are up to between videos! hnxmedia #GreatStuff #ExpandingFoam #TireRepair
Hint, fill a ballon with some of this, let it fully cure, then, flatten a spot. Does it rebound? nope, stays flattened. Might be fine for a lightweight push mower tire, but that's about it.
Yes, that is why I have reiterated in many comments that this is NOT for "weight bearing" tires or anything a living being would be transported upon. Small carts, pressure washer as shown here, etc only. Peace.
I used to work for a commercial tire shop that had a foam filler for the big tractor tires. As far as expansion goes I don't know if there was that much expansion. This is due to the filler you are using is for filling cracks around doors and windows, thus the need for expansion. The foam we used was monitored with a pressure gauge and there was a needle driven into the tire opposite the valve stem for venting air. When putting the foam fill in the tire the valve stem was on the bottom and the foam introduced until it started to bubble out through the pin in the top. At this time the pressure was obtained, the pump was shut down, valve replaced in the valve stem, and a nail used to plug the vent hole. Then curing. 24 to 48 hours, depending on how large of a tire we did. And we did several rear tractor tires. And these weren't garden tractors.
Thank YOU for these tips and information. I should certainly have been more clear about how the foam needs air to expand and set-up. The needle in the opposite end is brilliant! Thanks.
Wondered about how the shops did it. I had a friend who would take my wheelbarrow and lawn tractor tires and do them at his son's shop. Never knew how they did it but no more flats!
@@jackalley6451 WRONG!! This method ABSOLUTELY performs WONDERS in the rear tyres of my MURRAY 42” double fuxxer. I’ve BLOWN them FULL of pFOAM, 2 years ago, and performa perfecta, AMIGO!
When you add foam thru the valve stem with no way for the air to escape you end up with a tire full of foam and compressed air. As long as the compressed air doesnt leak out it seems to work. You have to have at least one air escape hole. If the air bleed hole is too small it might clog before the air escapes. I blew up an old tire once. Luckily it happened when I wasnt around. If you dont have a mess to clean up you didn't do it right. It still wont work for weight carrying tires.
You can also drill a few holes around the tire, to let the foam expand more evenly, you don't have to remove the valve stem. (I saw another youtuber do that.)
Yes, it would. It will allow air in to make it cure faster. However, I would actually recommend this fix instead: th-cam.com/video/swb-gQCIdes/w-d-xo.html
I did this twice on my lawn trailer tires and wasted 2 cans of Great Stuff trying this. The foam never expanded or solidified. I contacted the manufacturer and was told that the product needs MOISTURE to work properly. On my third attempt, I injected about 2 ounces of water into each tire, spun the tirs to distribute the water evenly, and then re-injeccted them with Great Stuff. This worked out very well and gave me great results! The manufacturer was adamant, however, that THIS IS NOT AN APPROVED USE OF THEIR PRODUCT.
LOL. I imagine they would frown on this use. However, here is my follow-up video: Expanding Foam in a Tire (Four Year Update Review) th-cam.com/video/N0VJbK0zJA8/w-d-xo.html but still recommend my Pool Noodle video the most.
My tube has gone bad many times. Pain in the rear and the wallet. I'm moving wood chips around the yard with my John Deere mower trailer and have one tube that went bad and sucked up into the tire. No valve stem is protruding. I notice that even with that weight in the tractor, the tire holds it pretty well. Thinking if the tire with a blown tube can handle the weight, then a foam filled would probably work. Not a fan of how expensive the foam is and the sticky mess, but I may try it.

Thanks for watching! Coincidentally, I have a follow-up video to this video dropping this weekend if you're interested. Thanks for posting a comment and stay well.
It has held up well for a year now. I have learned a lot from the suggestions in the comment section that I will use next time I do this. So far so good.
when you quickly put the core in to stop the foam from coming out, i assumed you screwed it in tight, but it looks like may not have because later you showed that air was escaping. can you explain exactly what you did. do you leave the core "partially" reinstalled????
That is the trickiest part. You have to allow a a small amount of air in the tire through the stem so that the foam will "set-up" (this type foam requires air to "activate"). If you seal the tire/valve too quickly, the foam will just be mushy inside the tire. Though I do not show it in this video, you can actually cut a small hole in the tire itself to increase the amount of available air for the foam to react with (the foam will eventually seal it back up. But to answer the question, when you're done, the valve is fully installed. Thanks for asking a great question. Peace.
@@HNXMedia hey i have a little scooter with pocket bike tyres..it only goes about 15mph max. it is about impossible to change the tyre and put in a new tube so i think i need to do the foam.. will it work at taht speed? and how will i know when i have enough foam in? im worried it wouldnt work its way all around and leave a flat spot also. would it be better do drill a hole on the opposite side, or do 3 holes spaced, sidewall or on tread???
@@joelsch8627 Friend, I would absolutely not feel comfortable suggesting to use this technique on anything that is designed to support a living being. This is only for yard/farm equipment as a "quick fix." But to answer the last question, yes drilling a hole in the opposite side of a tire would help increase the "air interaction" with the foam (and you would know when the tire was "full." Hope this helped. Peace.
I would do that exact thing. Just roll it back and forth with some pressure to make sure the whole 360 degree surface meets! Id glad wrap the top of the tire and puncture a whole through the top to let excess air escape and it would help distribute the foam better, dry better and be more uniform. Then use a puncture repair kit to fill the hole. bobs your uncle. You now have an invisible stable tire.
@Sebman33 thank you. I ended up using just 2 holes . One for air escape the other to insert the foam. Then switch halfway through spinning the whole time. If anything I got the first 2 too hard but it's better than flat. Great idea.
I've sold polyurethane systems for over 40 years and one can achieve all sorts of modulus using various chain stopping reactions. Urethanes can be light foam or and hard as a rock depending on when the reaction is stopped. The best system for this would be a soft rubbery consistency and filling the tire evenly is also desirable. Just my two cents worth. You just need to find someone with a lot of different formulas that they have experimented with for the best results. There are a few companies i've dealt with that make several different modulus urethanes.

I used "Great Stuff." I have learned that it helps to intentionally punch a hole in the tyre opposite the valve to allw more air in so that the foam will "cure." It will get hard and solid over time and may require a "refresh" if the foam breaks down. This is designed as a temporary fix for non-load-bearing items like the pressure washer shown in the video (or maybe a garden cart) - not a garden tractor or anything that would transport a living creature. Hope this helps. Thanks for watching.
The valve stem was used for more reliability. If you dont want to use a valve stem then go ahead and give it a try. You have no reason to be afraid of experimenting. I suppose you are a citizen of the "currently still free to express yourself United States of America".

The problem with your tyre seating is usually modern wheelbarrow wheels are injection moulded plastic wheels. They are so bad they are not round, and the tubeless tyre does not hold air. The cure is to fit a tube in the tyre, or get a metal wheel thats completely round.

When I filt the rear TYRES of my MURRAY 42” DUBBEL pFUXXER, I used 4 (FOUR) cans of expanded FOAM on each tyre. That was twoir yahrs AGO, and it finally CURED yesterday.
I have never tried this on riding lawnmower tires. I have tried a bunch of other methods to get through an extra season (paint & glitter/shredded plastic flakes). In the end, I just bought new tires and tubes. I think a riding mower is just required to carry too much weight for some of these fixes to work. I would only recommend this on "non-load bearing items." Peace.
I filt the rear TYRES of my MURRAY 42” DUBBEL fuxxer. Two YAHRS agoo. Used 4 (foar) cans in EACH tyre. Drilt 4 (foar) 1” (one unch) HOLS into the rim. It was a RIM JOB. Some people say “it won’t werk”, “yurts jest wasted my time”, but WRONG! I diddit twot yahes agoo, and it took almost a yahr and a hefe to cure. It finally cured and SET UP strong yesterday. So WRONG! All the never say never say nay not sayers; it DOES werk, just makes a complete pFukkan MESS oh JERROLD, lemme TELL YA!
This is not one of those cheap ones, it weighs a ton. I pull it up and down steps all the time. When the tires are flat it makes that part of the job a lot more difficult because it is prone to tipping.
My daughter got on my Craftsman lawn tractor after it had been sitting awhile. She said those tires are not around. I will get you new tires. That was the end of that experiment. I have heard of people putting the mower on blocks between uses. I've heard of drilling.holes in the flat spot and adding more foam. Hell no.
I actually already had the foam, but even at my local store it is only $3.50 (US) - and I have about 1/2 a can left over, so the cost for me would have been $1.75 (US).
Changing the tube is those style tires is a pain. They are extremely similar to a Hover Round Power Chair tire. PS the tubes at HFT used to be about $2.50 - 3.50 each.
This wont hold up long term. It will destroy your tire. I did thi to my wheel barrow and the tire is pretty much falling apart now. You are better off using Slime. It will puncture proof your tire and keep it air filled and last alot longer.
Actually, it did hold up for four years. The update video is here: th-cam.com/video/N0VJbK0zJA8/w-d-xo.html But truly, this is a better solution: th-cam.com/video/swb-gQCIdes/w-d-xo.html
I tried this, it works at first and then it starts to brake down inside the wheel. I used 4 cans. Best to do it on a Hot day. Two wheel lawn cart. I still had to buy myself 2 new tires. The price of those cans are not worth it, 4 cans + tax= 1 tire from Harbor Freight.
If his tire was truly full of foam he would not have been able to squeeze it like he did in the video. The best way is to lay the tire on its side and drill four holes on the sidewall and then allow the foam to expand and come out all four holes. The foam can expand like it should and the excess is easily cut off from the four holes.
But, see, it was full of foam, but just not set up yet. Yes, it helps a lot to have an additional "puncture" in the tire since the foam needs air to truly cure. In this video, I do not show that, but the foam in this tire still cured over time (about a 1/2 hour). Thanks for watching.
@@mateobrainardo4770 Thats why the poster says you need to drill holes in the tyres, but why destroy a perfectly good tyre, just get the puncture repaired. Something better would probably be the puncture proofing slime. We had a car tyre in our works as a demo, and used to stab it daily and it took weeks to lose pressure. It was like a sieve.
I pissed away a lot of time and money trying to do this on a Craftsman lawn tractor. This kind of foam can't handle a load for very long. The lawn tractor can take Chevy wheels. The thicker car tires dont pick up hedge Thornes so bad. I will be getting flat free tires for the front. I have a couple of 8 inch tires that have been filled at a heavy duty tire shop. If I use them I will need to weld in different wheel centers. Not sure what is in the professional filled tires but they are very heavy.
LOL. There is not even remotely enough compressed air in that can to fill up that tire. Now yes, some compressed air goes in with the foam, but the foam is what fills the bulk (if not all) of the case. Works even better if you put a hole in the tyre opposite the valve as others have suggested (that way you know when the foam comes fills completely and "air" causes the foam to cure faster).
Water (NOT “air”) activates & accelerates the set-up of the foam. It’s the humidity in the air that activates & accelerates the setting up of the foam not the air: it doesn’t air dry....smh Might consider putting some water inside the tyre first, swishing it around PRIOR to filling it with foam. Big Gap is the best. Not the window & door. Not the regular stuff either. You’re welcome.
Please don’t bad advice ! Save the great stuff for insulating your house, just put a tube in tire they make heavy duty! no mess ,toxic stains on hands or waste of gloves, no waiting around , carry the full load and offers air suspension🤣 I have used old tubes to line the tires with holes worn right through, then inserted a tube in no problems. don’t be lazy and fix it right when are you gonna have time to do it again?
You need a "Welcome Back" ceremony...for Mr. Cotter pin.
This comment deserves LEGENDARY status for the reference!
LOVE the twisted wire "Jesus" clip holding the tire on to the axle.
LOL. Nice catch! I have since replaced him t with a real cotter-pin. Thanks for watching and leaving a comment. This one made my day!

Something better would probably be the puncture proofing slime. We had a car tyre in our works as a demo, and used to stab it daily and it took weeks to lose pressure. It was like a sieve.
I pissed away a lot of time and money trying to do this on a Craftsman lawn tractor. This kind of foam can't handle a load for very long. The lawn tractor can take Chevy wheels. The thicker car tires dont pick up hedge Thornes so bad. I will be getting flat free tires for the front. I have a couple of 8 inch tires that have been filled at a heavy duty tire shop. If I use them I will need to weld in different wheel centers. Not sure what is in the professional filled tires but they are very heavy.
Buy inner tubes . Foam only works until the tire rotates under load

You filled it with more compressed air then anything.
LOL. There is not even remotely enough compressed air in that can to fill up that tire. Now yes, some compressed air goes in with the foam, but the foam is what fills the bulk (if not all) of the case. Works even better if you put a hole in the tyre opposite the valve as others have suggested (that way you know when the foam comes fills completely and "air" causes the foam to cure faster).
air doesn't help any reaction with this stuff. For polyurethane moisture does.

Water (NOT “air”) activates & accelerates the set-up of the foam.
It’s the humidity in the air that activates & accelerates the setting up of the foam not the air: it doesn’t air dry....smh
Might consider putting some water inside the tyre first, swishing it around PRIOR to filling it with foam.
Big Gap is the best.
Not the window & door.
Not the regular stuff either.
You’re welcome.

After a while the foam will start breaking down. I recommend not using it either put a tube in it or replace the tire.
Please don’t bad advice ! Save the great stuff for insulating your house, just put a tube in tire they make heavy duty! no mess ,toxic stains on hands or waste of gloves, no waiting around , carry the full load and offers air suspension🤣 I have used old tubes to line the tires with holes worn right through, then inserted a tube in no problems. don’t be lazy and fix it right when are you gonna have time to do it again?

First of all your filling foam in a tube. It’s not a tub less tire. I would like to see it done on a tub less tire 🛞

Are you kidding me?
Nope. If this was the strangest thing I'd done on my channel, I would have a lot fewer videos. Peace.
Please don’t do this this is the stupidest thing I’ve ever seen...
Yet you watched and I thank you for that. Works for me. Still solid a year later. But hey, to each their own. Peace.
I did this on my barrow..6 months later she's still pumping. what's your issue?
