Intheswamp, I have like 6 of these carts and the tubeless tires are always leaking. Got a whole pallet of these plastic rims with tires from the junkyard. Continental tires, good stuff. Is filling them with foam going to work ? Put 1/4 inch holes every 90 degrees and filled them. It's OK if they are not buoyant, just not sure if they are going to be lumpy. Ideas ?? Just filled them 5 minutes ago. Once witnessed an old car having the interior filled w/concrete to window level. Had to be removed with a crane. It was a prank orchestrated by a college fraternity. I also left one of those cheap 12 volt compressors with the snap on filler on one of the three wheelers with giant tires. Heard an explosion from the house. Walked out and found the three wheeler upside down(sitting on the seat and handle bars). (Rear)Tire in pieces. Dang those cheap compressors can generate some pressure.

IntheswampHey Ed. Where are you ? Just letting you know this was a great success. Used 'Great Stuff", the type for 'Gaps and Cracks'. One can per tire. I had researched having my tractor tires foamed. It is done. And the cost was $500-$600 !! Betcha the Snapper riding mower tires would do well with this treatment. Maybe too much weight that would deform the foam upon sharp impacts within though.

Dang...somehow I missed this!!! Looks like there was no solemn "Houston, we have a problem" communication. Well, all I can say is that's some "Great Stuff"!!!!<grin> Foam-filling is a good option on leaky tires that can be disposable. Never done it myself, but looks like you handled it quiet nicely. Great Stuff needs to be protected from the elements so inside the tire is good...maybe smear some RTV or something over the drill holes but the holes are probably so small it really won't make a difference. A guy down around Navarre Beach was doing some major beach clean-up after a hurricane came through...lots of glass and metal. He got tired of his big front-end loader having flats so he foam-filled the tires. Almost destroyed the machine and he had to ditch the tires/rims...no "give"/shock-absorption and it was beating the machine apart. Seems that was the perfect application for foam but something wasn't right about the application...either the sand dunes didn't give enough or the tires were filled to tightly or maybe to dense of a foam was used...I don't know. How is your tractor riding...can you tell any difference? Initially a problem that people ran into with foam-filling was once the tires wear out the were the dickens to get off the rim...sawzall time. I'm sure that technique has been refined by now. Wheelbarrow tires...perfect candidates for foam-filled tires...thin-walled and start losing air as soon as the sun hits them...infrequent use by homeowners find them always flat...popped loose from the rim...hard to re-air. Foam fixes that. Your tires...wheelbarrow/yard-trailer tires? Neat experiment...I might even try that on something.

Foam fixes that. Your tires...wheelbarrow/yard-trailer tires? Neat experiment...I might even try that on something. They are exact size of large wheel barrow tires and wheels. 3/4 inch bore. Torched the old axle and welded 3/4 rod. Tack welded washer to hold. For a push cart it is fine. The industrial junkyard had about 30 stacked on a pallet. Got a pile of 3/4 solid rod at the boneyard. so the marriage. Hard ball sized blobs of foam cam out of the holes the first hour. Don't think one can Great Stuff would do two tires, but easily one. What pressure are in them LOL ? I hear you about removal. Sawzall job. You may get away with using the 'big hole' foam. It is less dense. thanks for the tip on sealing the holes, never thought about that.

Well, I was make a mold out of a two part expanding foam, I bought at McMaster Carr. It's used for floating boat docks. I mixed it in a cup and by the time it dried in about 20mins. It was so hard that I could not mash it. Don't know how hard that stuff is but if you need to try something else.

Some of those foams can blow out walls and doors when filled. Tire looks like it has 80 psi judging from the bulge lol. Good thing there was 4 relief holes. Thanks for the tip spice.
