Ya'll are better than google!! Small tires, like wheelbarrow tires, going flat. Anyway to foam fill them myself? Not worried about weight or them being hard and rough. I want them solid and won't go flat anymore.

Try a tire plug kit from the gas station or autozone, that should work. If it a small leak some foam might work. When my wheel barrow sits for a while the tire goes low.

Maybe I should have been more clear. This is something my wife uses so it is put through hell!! I don't want air in the tires. I want something she can drive a nail in and it won't go flat.

I put slime in my wheelbarow tires, and haven't added air since.

just go to harbor freight and buy a flat free tire. should be less than $20

This^^^ or you could use expanding foam like Great Stuff.

At $20 I'd probably be better buying new ones. I have read Great Stuff gets brittle and breaks up when put in tires.

Just take the tire off and use the handles to pull with. You did say it was your wife's?

I have friend that races Figure 8 here in Missouri. He drives Caviler's and Grandam's in the races. Runs expanded foam insulation filled donuts tires. He takes the valve stem out for air to escape, drills a hole in the sidewall of the donut tire opposite of the valve stem. Stands the tire with the valve stem facing at 12:00, sticks the foam insulation tube in the drilled hole and fills the tires up until foam is coming out the valve stem and puts the valve core back in.

We use Gempers Bulletproof foam in everything. It is the only thing we have found that will stand up to Osage Orange thorns.
