Have seen video of folks spraying the expanding foam into tires to make them usable.  This is off the Gurilla cart.  Wheels are about 4 years old.  Did not know such little tires ever had tubes in them anymore.  Saw a couple of videos on youtube where folks just drilled a few holes in the tires to release the air, and to have a few points to put in the foam.

Letting it set up till tomorrow hoping 20 hours will be a long enough cure.  I realized it was going to way over expand, just not quite this much.  Used the whole can, cuz the manufacture even states, you will find it very difficult to ever use again.  What I was not smart enough to do was plug the 3 drill holes and the valve stem hole.  I think if I had done that, the tire would have been much firmer.  I think it is going to work, just believe if the stuff had not been able to escape, it would have made the tire much stiffer.

Pretty sure a new tube would have been at least $10, and new tire maybe $20...This can was of Great Stuff was under $3 with tax!  I guess we see tomorrow if it works!

Or a patch for $1

 I would say you have enough foam..My  only concern would be if the foam will be firm enough to support the load w/o breaking down.. Time will dictate the outcome.

That's an interesting fix, have never seen that before. Interested to see how it does.

Take tube out (pain), have to deal with the 8 oz of Slime sealant that is in the tube (will get mad enough to break something in garage), find hole(s), repair with X amount of patches, have to put back on tire and hope it holds...OR...rip tube out of tire with it still on rim, drill 3 holes, inject $3 worth of foam, put back on cart and it works great.

My time ain't worth much, but my sanity is!

My concern also, but will never go over 5mph, so hoping that mitigates any deformation issues!

That is about 150lbs. of wood and it does not seem to be deformed, so time will tell, but happy so far!

You would think that the little stuff on the wheels is just stuff that got stuck as I was filling.  Those were actually cracks in the rubber I could not even see and as the foam expanded and I am assuming the drilled holes & valve stem started to get plugged , the foam started to extrude from them.

I've got the same wagon and the tires are always low.  Let us know how it turns out.  It's not like it'll be hitting high speeds.

When that first picture came up, I wanted to grab a spoon and dig into that ice cream! 

[LowSlowJoe]

Ha...  I was just thinking 'Bentley, you sure made a mess'.

I had the same problem with the tires on my hose cart, Harbor Freight has replacements for cheap (less than $5 on sale).

[BC Buck]

I was going to suggest Harbor Freight also but they would soon be leaking . Keep us updated on the fix.

[Bentley]

Only been 5 days, but working great and has about 200lbs. of wood in it now.

I have one of those carts up at the cabin.  Works great.

Solid rubber tires are great.  They do produce a bumpier ride but never go flat.  I worked in several auto plants while putting myself through college and that's all they used on equipment and bicycles due to flat hazards.  Pneumatic tires always give me problems on the few pieces of equipment that I have them on.  My miter saw table uses them and I can always bet on them being flat and the bead broken when it's needed.  It seems I spend more time getting the bead to seat and getting the tires inflated than using the saw.
