Here are the tools & materials I have used in this video - please use my link if you would like to buy: ✅ ✅ 👉 Tire valve stem remover: amzn.to/4a6nFFS ✅ ✅ 👉 Loctite spray foam: amzn.to/3UurXRF ✅ ✅ 👉 Foam nozzles: amzn.to/3Uv85hD Thanks!
If you follow the method shown here you are going to fail. I used to foam fill tires for industrial equipment and this IS NOT how it's done. When he presses on the tire at the end and it gives way, that is trapped air which can create real problems in operation. To properly fill a small tire like this, the first thing you do is to deflate it and then remove the valve stem entirely. Directly opposite of the valve stem, you drill a hole sized so that a bolt, in the case 5/16 or 3/8 would be about right, will tread into it and stay in place. Ideally with a tire this small the hole should be drilled thought the side wall where it meet with the tread. Once your hole is drilled, set the tire up tilted vertically so the hole is at the top. The reason for the drilled hole is to vent all air out as the foam expands so there are no voids like he has here. Start spraying your foam in through the valve stem and keep filling until pure foam is coming out of the hole which indicates that the void is now completely filled. Screw the bolt in to the hole and let the hole thing sit for 48 hours to allow the foam to cure. Under no circumstance should you invert the can while spraying because all you are doing is wasting the propellant in the can and the can will not empty completely. Make sure you have enough canned foam to do the job to completion since you only get one chance with it and you can't run to the store to get more. When larger tires are done, you use a special mixer nozzle through an additional hole in the tire carcass with the A + B components so it foams inside the tire and expands from there to fill it. The bolt holes are equidistant from one another on the tire circumference and through the middle of the tire tread. Other wise the filling and venting are pretty much the same in practice.
think you need to buy a new tire now. But might as well use it until it fails as there is no longer a fix, rim is bent anyway. You may get lucky and it will outlast mower. Usually when you invert a can of foam, it only expels the propellant. It is designed to be upright when pushing the foam out of can.
You need to add a little moisture inside the tire. Spray foam is moisture cure. A hole on the other side of the tire would help to insure that you are getting it full.
A solid tire makes a wheelbarrow noticeably harder to push. You can’t remove a foamed tire off of the rim. Making it necessary to buy a tire & wheel assembly. Which also comes with a cheap Chinese tire like the wheelbarrow. Just buy a 4ply wheelbarrow tire & tube to begin with. From my experience.

Thanks!
Why not just drill into the side wall of the tire and insert spray foam from the drilled holes?
Great idea! I think i will try this soon

That clarifies things perfectly, thank you!
LOL clever, I have never thought about filling foam into small tires.
👍
Would the foam deflate over time?
